Adult Aspirin Regimen

Drug overview for ADULT ASPIRIN REGIMEN (aspirin):

Generic name: aspirin (AS-pir-in)
Drug class: Low dose Aspirin (81 mg or less)
Therapeutic class: Hematological Agents

Aspirin (the prototype of the salicylates) is a nonsteroidal anti-inflammatory agent (NSAIA) and also exhibits antithrombotic, analgesic, and antipyretic activity.

Aspirin is used extensively in the treatment of mild to moderate pain, fever, and inflammatory diseases. Aspirin is also used in the prevention of arterial and venous thrombosis. Aspirin, however, should be used with extreme caution, if at all, in patients in whom urticaria, angioedema, bronchospasm, severe rhinitis, or shock is precipitated by other salicylates or other NSAIAs.

(See Cautions: Sensitivity Reactions in the Salicylates General Statement 28:08.04.24.)

Dosing
Administration
ADULT ASPIRIN REGIMEN
ASPIRIN EC

Dosage of aspirin must be carefully adjusted according to individual requirements and response, using the lowest possible effective dosage. When used at high (e.g., anti-inflammatory) dosages, the development of tinnitus can be used as a sign of elevated serum salicylate concentrations, except in patients with high-frequency hearing impairment.

When preparations containing aspirin in fixed combination with other drugs are used, the cautions, precautions, and contraindications applicable to each ingredient must be considered.

Following oral administration of single doses of rapidly absorbed aspirin dosage forms, salicylate is detected in serum within 5-30 minutes, and peak serum salicylate concentrations are attained within 0.25-2 hours, depending on dosage form and specific formulation. Clinically important differences in the onset or intensity of analgesia produced by rapidly absorbed dosage forms or specific preparations have not been established.

Following oral administration of a single 650-mg dose of aspirin as an effervescent or noneffervescent aqueous solution in healthy adults, average peak plasma aspirin concentrations of about 13 mcg/mL are attained within 15-40 minutes and average peak plasma salicylate concentrations of about 40-55 mcg/mL are attained within 30-60 minutes. After a single 650-mg oral dose of aspirin (as two 325-mg uncoated plain tablets) in fasting healthy adults, average peak plasma aspirin concentrations of about 7-9 mcg/mL occur within 25-40 minutes and average peak plasma salicylate concentrations of about 35-50 mcg/mL occur within 1.5-2 hours.

Following oral administration of a single 650-mg dose of buffered aspirin (as 2 tablets, each containing 325 mg of aspirin), average peak plasma salicylate concentrations of about 40-60 mcg/mL are attained within 45-60 minutes.

In one study in healthy fasting adults given a single 975-mg oral dose of aspirin (as three 325-mg uncoated plain tablets), peak serum salicylate concentrations averaged 60-75 mcg/mL and occurred within 2 hours. In another study in fasting rheumatoid arthritis patients given a single 1.95-g oral dose of aspirin (as six325-mg uncoated plain tablets), peak plasma aspirin concentrations of about 12-16 mcg/mL occurred within 1 hour and peak plasma salicylate concentrations of about 110-160 mcg/mL occurred within 4 hours. When these patients were given the same dose of buffered aspirin (as 6 tablets, each containing 325 mg of aspirin), peak plasma aspirin concentrations of about 14-18 mcg/mL occurred within 1-2 hours and peak plasma salicylate concentrations of about 140-160 mcg/mL occurred within 1-2 hours.

Aspirin is usually administered orally, preferably with food or a large quantity (240 mL) of water (unless the patient is fluid restricted) or milk to minimize gastric irritation. In patients unable to take or retain oral medication, aspirin suppositories may be administered rectally; however, rectal absorption may be slow and incomplete. (See Pharmacokinetics: Absorption.)Aspirin tablets should not be administered rectally, since they are likely to cause irritation and erosion of the rectal mucosa.

Aspirin preparations should not be used if a strong vinegar-like odor is present. (See Chemistry and Stability: Stability.) If an unpleasant taste or aftertaste, burning in the throat, or difficulty in swallowing occurs with uncoated aspirin-containing tablets, these effects may be reduced with film-coated tablets. Although specific data are not available, these effects are also likely to be reduced with enteric-coated tablets.

If gastric irritation and/or symptomatic GI disturbances occur with uncoated aspirin-containing tablets, these effects may be reduced with enteric-coated tablets or extended-release tablets. If a liquid dosage form of aspirin is desired for short-term treatment of pain, an oral solution may be prepared from commercially available effervescent tablets (e.g., Alka-Seltzer(R)) by dissolving tablets in 120 mL of water; ingest the entire solution to ensure adequate dosing. In addition to potentially reducing adverse GI effects, some clinicians suggest that enteric-coated tablets may be swallowed more easily by children receiving chronic therapy with the drug and may therefore result in increased compliance.

Aspirin or buffered aspirin preparations should not be chewed before swallowing for at least 7 days following tonsillectomy or oral surgery because of possible injury to oral tissues from prolonged contact with aspirin particles. In addition, aspirin or buffered aspirin tablets should not be placed directly on a tooth or gum surface because of possible injury to tissues. Capsules containing the fixed combination of aspirin and extended-release dipyridamole should be swallowed whole and should not be chewed.

Chewable aspirin tablets may be chewed, crushed, and/or dissolved in a liquid, or swallowed whole, followed by approximately 120 mL of water, milk, or fruit juice immediately after administration of the drug. For information on the concomitant administration of aspirin with nonsteroidal anti-inflammatory agents (NSAIAs), see Drug Interactions: Nonsteroidal Anti-inflammatory Agents, in the Salicylates General Statement 28:08.04.24.

There are 1 contraindications. These drug combinations generally should not be dispensed or administered to the same patient. A manufacturer label warning that indicates the contraindication warrants inclusion of a drug combination in this category, regardless of clinical evidence or lack of clinical evidence to support the contraindication.

Drug Interaction	Drug Names
Mifepristone/Anticoagulants; Antiplatelets SEVERITY LEVEL: 1-Contraindicated Drug Combination: This drug combination is contraindicated and generally should not be dispensed or administered to the same patient. MECHANISM OF ACTION: Anticoagulants may result in excessive bleeding following the abortion. CLINICAL EFFECTS: The concurrent use of mifepristone with anticoagulants may result in excessive bleeding following the abortion. PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs). PATIENT MANAGEMENT: The manufacturer of mifepristone states that mifepristone is contraindicated in patients receiving concurrent anticoagulant therapy.(1) If concurrent therapy is deemed medically necessary, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated or discontinued. Contact the prescriber before initiating, altering the dose or discontinuing either drug. DISCUSSION: The manufacturer of mifepristone states that mifepristone is contraindicated in patients receiving concurrent anticoagulant therapy.(1)	MIFEPREX, MIFEPRISTONE

Drug Interaction	Drug Names
Influenza Virus Vaccine Live/Salicylates SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Use of salicylates during influenza infection has been associated with Reye's Syndrome.(1,2) CLINICAL EFFECTS: Use of the live influenza virus vaccine in children and adolescents (patients age 2-17 years) receiving salicylate therapy may increase the risk of Reye's Syndrome.(1,2) Symptoms of Reye's syndrome include drowsiness, confusion, seizures, coma. In severe cases, Reye's syndrome can result in death. PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: The use of live influenza virus vaccine in children and adolescents (patients age 2-17 years) receiving salicylate therapy is contraindicated.(1,2) Use of salicylates should be avoided for 4 weeks after administration of live influenza vaccine.(1) DISCUSSION: Because the use of salicylates during influenza infection has been associated with Reye's Syndrome, the use of live influenza virus vaccine in children and adolescents (patients age 2-17 years) receiving salicylate therapy is contraindicated.(1,2)	FLUMIST TRIVALENT 2024-2025
Varicella Virus Vaccine Live/Salicylates SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Use of salicylates during natural varicella infection has been associated with Reye's Syndrome.(1-4) CLINICAL EFFECTS: Use of the live varicella virus vaccine in patients receiving salicylate therapy or use of salicylates within 6 weeks after vaccination with the live varicella virus vaccine may increase the risk of Reye's Syndrome.(1-4) Symptoms of Reye's syndrome include drowsiness, confusion, seizures, coma. In severe cases, Reye's syndrome can result in death. PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: The Canadian, UK, and US manufacturers of live varicella virus vaccine indicated for the prevention of chicken pox state that vaccine recipients should avoid the use of salicylates for 6 weeks after vaccination.(1-4) There is no such restriction in the labeling for live varicella virus vaccine indicated for the prevention of shingles, which is only indicated for patients age 60 and older.(5) DISCUSSION: Because the use of salicylates during natural varicella infection has been associated with Reye's Syndrome, the use of salicylates for 6 weeks following vaccination with live varicella virus vaccine should be avoided.(1-4)	PROQUAD, VARIVAX VACCINE
Sodium Phosphate Bowel Cleanser/NSAIDs; Salicylates SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Bowel cleansing with sodium phosphate causes dehydration, decreased intravascular volume and hyperphosphatemia, which increases phosphate levels in the renal tubules. Abnormally high levels of calcium and phosphate in the renal tubules may precipitate out, resulting in renal injury.(1) CLINICAL EFFECTS: Use of sodium phosphate for bowel cleansing in patients maintained on nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the risk of acute phosphate nephropathy, which is an acute kidney injury associated with deposits of calcium phosphate crystal in the renal tubules that may result in permanent renal function impairment. Acute phosphate nephropathy presents as acute kidney injury with minimal proteinuria and a bland urine sediment.(2) Use of oral sodium phosphate products at laxative doses has not been associated with acute kidney injury.(3) PREDISPOSING FACTORS: Patients who may be at an increased risk of acute phosphate nephropathy include those who are over age 55; are hypovolemic or have decreased intravascular volume; have baseline kidney disease, bowel obstruction, or active colitis; and who are using medications that affect renal perfusion or function (such as diuretics, ACE inhibitors, angiotension receptor blockers [ARBs]), and NSAIDs.(2) PATIENT MANAGEMENT: If possible, use an alternative agent for bowel cleansing.(1) Use sodium phosphate products with caution in patients taking medications that affect kidney function or perfusion, such as ACE inhibitors or ARBs. Obtain baseline and post-procedure labs (electrolytes, calcium, phosphate, BUN, creatinine, and [in smaller, frail individuals] glomerular filtration rate). Instruct patients to drink sufficient quantities of clear fluids before, during, and after bowel cleansing and to avoid other laxatives that contain sodium phosphate. Consider hospitalization and intravenous hydration during bowel cleansing to support frail patients who may be unable to drink an appropriate volume of fluid or who may be without assistance at home.(2) Use of an electrolyte solution for rehydration may decrease the risk of acute phosphate nephropathy.(4,5) DISCUSSION: Since May 2006, the FDA has received 20 reports of acute phosphate nephropathy associated with the use of Osmo Prep. Concomitant medications included ACE inhibitors or ARBs (11), diuretics (6), and NSAIDs (4).(2) In a retrospective review of colonoscopy patients, simultaneous use of ACE inhibitors or ARBs significantly increased the risk of acute kidney injury from oral sodium phosphate. Diuretic use was also a risk factor.(6) In a case series study of 21 cases of acute phosphate nephropathy in patients who had used oral sodium phosphate, 14 patients received an ACE inhibitor or ARB, 4 used a diuretic, and 3 used an NSAID.(7) Cases have also been reported with rectal products.(8)	MB CAPS, SODIUM PHOSPHATE DIBASIC, URIMAR-T, URNEVA
Anagrelide/Aspirin SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Anagrelide may affect platelet function in a way that synergizes with low-dose aspirin.(1) CLINICAL EFFECTS: Concurrent use of anagrelide and aspirin may increase the risk of hemorrhage.(1,2) PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs). PATIENT MANAGEMENT: The concurrent use of anagrelide and aspirin should be approached with caution, especially in patients with a high risk profile for hemorrhage.(2) If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. DISCUSSION: In healthy subjects, the administration of of single dose anagrelide (1 mg) and aspirin (900 mg) or multiple dose anagrelide (1 mg daily) and aspirin (75 mg daily) resulted in greater anti-platelet aggregation effects than aspirin alone. Concurrent single doses of both anagrelide and aspirin had no effects on bleeding time, prothrombin time, or activated partial thromboplastin time.(2) A study in 809 patients with essential thrombocythemia compared the combination of low-dose aspirin with hydroxyurea to the combination of low-dose aspirin with anagrelide. While patients receiving low-dose aspirin with anagrelide had lower rates of venous thromboembolism, the combination was associated with increased rates of arterial myelofibrosis, serious hemorrhage, and transformation to myelofibrosis.(1)	AGRYLIN, ANAGRELIDE HCL
Ketorolac (Non-Injectable)/Aspirin (Less Than or Equal To 300 mg) SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: There are two potential mechanisms: 1) Possible additive or synergistic pharmacodynamic side effects from concurrent NSAID use.(1,2) 2) Ketorolac is a reversible platelet inhibitor, while aspirin is an irreversible platelet inhibitor. CLINICAL EFFECTS: Concurrent use of multiple doses of ketorolac with aspirin may result in increased risk for NSAID-related side effects such as bleeding.(1,2) Nonselective NSAIDs such as ketorolac may interfere with the antiplatelet effects of aspirin.(3) PREDISPOSING FACTORS: Bleeding risk may increase due to disease (e.g. recent GI ulcer or bleed) or other concurrent drugs (e.g.anticoagulants, heparinoids). Elderly patients are at increased risk for severe GI events from ketorolac.(1,2) The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (NSAIDs). PATIENT MANAGEMENT: The manufacturer of prescription extended-release aspirin used for cardiovascular protection notes that concurrent treatment with NSAIDs may interfere with the antiplatelet effect of aspirin and increase the risk for NSAID associated bleeding or renal impairment, but does not contraindicate concurrent use.(3) However, manufacturers of ketorolac state that concurrent use of ketorolac with aspirin is contraindicated.(1,2) If concurrent therapy or ketorolac with low dose aspirin is needed, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin and/or hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. Conduct periodic monitoring of renal function, especially in patients with preexisting renal impairment. Instruct patients to report any signs and symptoms of bleeding, such as unusual bruising; red or black, tarry stools; acute abdominal or joint pain and/or swelling. DISCUSSION: Based upon similar pharmacodynamic effects and potentially cumulative risks for serious NSAID-related adverse events, manufacturers of ketorolac state the concurrent administration of ketorolac with other NSAIDs or aspirin is contraindicated.(1,2) Prescribing information for an FDA approved lower strength prescription aspirin product used for cardiovascular risk reduction describes potential interactions, but does not contraindicate concomitant NSAID use.(3)	KETOROLAC TROMETHAMINE, SPRIX
Ketorolac (Injectable)/Aspirin (Less Than or Equal To 300 mg) SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.

Conduct periodic monitoring of renal function, especially in patients with preexisting renal impairment. Instruct patients to report any signs and symptoms of bleeding, such as unusual bruising; red or black, tarry stools; acute abdominal or joint pain and/or swelling. DISCUSSION: Based upon similar pharmacodynamic effects and potentially cumulative risks for serious NSAID-related adverse events, manufacturers of ketorolac state the concurrent administration of ketorolac with other NSAIDs or aspirin is contraindicated.(1,2) Prescribing information for an FDA approved lower strength prescription aspirin product used for cardiovascular risk reduction describes potential interactions, but does not contraindicate concomitant NSAID use.(3)	BUPIVACAINE-KETOROLAC-KETAMINE, KETOROLAC TROMETHAMINE, R.E.C.K.(ROPIV-EPI-CLON-KETOR), ROPIVACAINE-CLONIDINE-KETOROLC, ROPIVACAINE-KETOROLAC-KETAMINE, TORONOVA II SUIK, TORONOVA SUIK
Caplacizumab/Anticoagulants; Antiplatelets SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Bleeding has been reported with the use of caplacizumab.(1) CLINICAL EFFECTS: Concurrent use of caplacizumab with either anticoagulants or antiplatelets may increase the risk of hemorrhage.(1) PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. hemophilia, coagulation factor deficiencies). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs). PATIENT MANAGEMENT: Avoid the use of caplacizumab with anticoagulants and antiplatelets. Interrupt caplacizumab therapy if clinically significant bleeding occurs. Patients may require von Willebrand factor concentrate to rapidly correct hemostasis. If caplacizumab is restarted, closely monitor for signs of bleeding.(1) If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory tests (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated or discontinued. Contact the prescriber before initiating, altering the dose or discontinuing either drug. DISCUSSION: Bleeding has been reported with caplacizumab. In clinical studies, severe bleeding adverse reactions of epistaxis, gingival bleeding, upper gastrointestinal hemorrhage, and metrorrhagia were each reported in 1% of patients. Overall, bleeding events occurred in approximately 58% of patients on caplacizumab versus 43% of patients on placebo.(1) In post-marketing reports, cases of life-threatening and fatal bleeding were reported with caplacizumab.(1)	CABLIVI

There are 23 moderate interactions. The clinician should assess the patient’s characteristics and take action as needed. Actions required for moderate interactions include, but are not limited to, discontinuing one or both agents, adjusting dosage, altering administration.

Drug Interaction	Drug Names
NSAIDs; Salicylates/Loop Diuretics SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: During concurrent administration of a loop diuretic and a nonsteroidal anti-inflammatory drug (NSAID), patients may retain sodium as a result of NSAID-induced prostaglandin inhibition. CLINICAL EFFECTS: The pharmacological effects of loop diuretics may be decreased due to reduced antihypertensive and diuretic actions. Concurrent use of NSAIDs with loop diuretics and renin-angiotensin system (RAS) inhibitors may result in increased risk of acute kidney injury (AKI). PREDISPOSING FACTORS: Low water intake/dehydration, drug sensitivity, greater than 75 years of age, and renal impairment may increase an individuals susceptibility to AKI. PATIENT MANAGEMENT: Monitor patients for a decrease in the effects of the loop diuretic. It may be necessary to administer a higher dose of the diuretic or an alternative anti-inflammatory agent. Concurrent use of NSAIDs with loop diuretics and RAS inhibitors should be used with caution and monitored closely for signs of AKI. DISCUSSION: In a computational study, the risk of AKI using triple therapy with a diuretic, RAS inhibitor, and NSAID was assessed. The study found the following factors may increase an individual's susceptibility to AKI: low water intake, drug sensitivity, greater than 75 years of age, and renal impairment.(19,20) In an observational study, current use of a triple therapy with a diuretic, RAS inhibitor, and NSAID, was associated with an increased rate of acute kidney injury (rate ratio (RR) 1.31, 95% confidence interval (CI) 1.12-1.53). The highest risk of AKI associated with triple therapy were observed in the first 30 days of use (RR 1.82, CI 1.35-2.46). (21) Administration of indomethacin alone has been reported to decrease sodium excretion and increase blood pressure. In patients receiving a loop diuretic (e.g., bumetanide, furosemide), these effects interfere with clinical management. Several NSAIDs have been shown to interact with loop diuretics interfering with the pharmacological effects of the diuretic. In volunteers on sodium restricted diets, ibuprofen and indomethacin inhibited furosemide diuresis.

NSAIDs; Salicylates/Lithium SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Decreased renal excretion of lithium, possibly resulting from NSAID-induced prostaglandin inhibition. CLINICAL EFFECTS: May observe increased lithium toxicity. PREDISPOSING FACTORS: Risk factors for lithium toxicity include: renal impairment or worsening of existing renal disease, dehydration, low sodium diet, and concomitant use of multiple medications which may impair renal elimination of lithium (e.g. ARBs, ACE Inhibitors, NSAIDs, diuretics). Patients who require higher therapeutic lithium levels to maintain symptom control are particularly susceptible to these factors. PATIENT MANAGEMENT: The magnitude of this interaction is highly variable. Patients with predisposing factors, e.g. dehydration, renal impairment, or concurrent use of other agents which may impair lithium elimination, are expected to have a higher risk for lithium toxicity. If both drugs are administered, monitor plasma lithium levels and observe the patient for signs and symptoms of lithium toxicity or changes in renal function. Full effects of the addition or an increase in NSAID dose may not be seen for one to two weeks. Adjust the dose of lithium accordingly. If lithium is to be started in a patient stabilized on chronic NSAID therapy, consider starting with a lower lithium dose and titrate slowly as half-life may be prolonged. Monitor lithium concentrations until stabilized on the combination. Counsel the patient to contact their prescriber before starting an OTC NSAID. Assure that patients are familiar with signs and symptoms of lithium toxicity (e.g. new or worsening tremor, nausea/vomiting, diarrhea, ataxia, or altered mental status) and to report signs and symptoms of toxicity. DISCUSSION: Numerous studies and case reports have been documented that administration of a NSAID to a patient stabilized on lithium therapy may result in increased serum lithium levels and possible toxicity. Full effects may take 1 to 2 weeks to develop and may persist for a week after the NSAID is discontinued.

Angiotensin II Receptor Blocker (ARB)/NSAIDs; Salicylates SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Angiotensin II receptor blockers (ARBs) can cause vasodilation of the efferent renal arteriole which may result in decreased glomerular filtration rate. NSAIDs inhibit prostaglandin synthesis which can lead to afferent arteriolar vasoconstriction and may negate any decrease in blood pressure. CLINICAL EFFECTS: Concurrent use of ARBs with NSAIDs may result in decreased antihypertensive effects. In patients with existing renal impairment, the use of these agents together may also result in further deterioration of renal clearance caused by renal hypoperfusion. Concurrent use of ARBs with NSAIDs and diuretics may result in increased risk of acute kidney injury (AKI). PREDISPOSING FACTORS: Low water intake/dehydration, drug sensitivity, greater than 75 years of age, and use of diuretics can lead to hypovolemia and increased risk of AKI. PATIENT MANAGEMENT: Patients maintained on ARBs should be monitored for a loss of blood pressure control and a change in renal function if an NSAID is added to their regimen. Patients receiving concurrent therapy may require higher doses of ARBs. If blood pressure control cannot be achieved or if the patient's renal function deteriorates, the NSAID may need to be discontinued. Patients should be monitored for hypotension if NSAIDs are withdrawn from concurrent ARB therapy. Concurrent use of ARBs with NSAIDs and diuretics should be used with caution and monitored for signs of AKI. DISCUSSION: In a computational study, the risk of AKI using triple therapy with a diuretic, renin-angiotensin system (RAS) inhibitor, and NSAID was assessed. The study found the following factors may increase an individual's susceptibility to AKI: low water intake, drug sensitivity, greater than 75 years of age, and renal impairment.(22,23) In an observational study, current use of a triple therapy combination was associated with an increased rate of acute kidney injury (rate ratio (RR) 1.31, 95% confidence interval (CI) 1.12-1.53). The highest risk of AKI associated with triple therapy were observed in the first 30 days of use (RR 1.82, CI 1.35-2.46).(24) In a population based cohort study, the concurrent use of NSAIDs with renin-angiotensin system (RAS) inhibitors in 5,710 hypertensive patients stabilized on antihypertensive therapy required hypertension treatment intensification. Adjusted hazard ratios (HR) for hypertension treatment intensification were 1.34 [95% CI 1.05-1.71] for NSAIDs in general, 1.79 (95% CI 1.15-2.78) for diclofenac and 2.02 (95% CI 1.09-3.77) for piroxicam. There were significant interactions between NSAIDs and angiotensin converting enzyme inhibitors (ACE inhibitors; HR 4.09, 95% CI 2.02-8.27) or angiotensin receptor blockers (ARBs; HR 3.62, 95% CI 1.80-7.31), but not with other antihypertensive drugs.

Valproic Acid/Salicylates SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Multiple mechanisms appear to be involved. Salicylates may displace valproic acid from plasma protein binding sites. Salicylates may also affect the metabolism of valproate by increasing conjugation and decreasing oxidation of valproic acid. CLINICAL EFFECTS: Concurrent use of salicylates may increase the unbound fraction of serum valproic acid concentration, resulting in toxicity. PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: Patients receiving concurrent salicylate therapy should be observed for signs of valproic acid toxicity (e.g., ataxia, drowsiness, nystagmus, tremor). The dosage of valproic acid may need to be adjusted. DISCUSSION: In two studies involving 6 epileptic children taking valproic acid, concurrent aspirin led to an increase in serum valproic acid free fraction and an increased half-life. Renal clearance of free valproic acid was found to decrease.(1,2) In another study involving 5 children, concurrent valproic acid and aspirin resulted in a decrease in free valproic acid clearance although total valproic acid levels did not change significantly.(3) However, one study reported that the concurrent use of valproic acid and aspirin leads to an increased excretion of valproic acid and a decreased total salicylate excretion.(4) In 3 case reports, aspirin given to children taking valproic acid resulted in valproic acid toxicity (tremor, nystagmus, truncal ataxia). There was an increase in free valproic acid levels in two cases, however, a reduction in the free fraction and the total valproic acid levels occurred in the third patient.(5) In another case report, a patient was maintained on divalproex sodium (2500 mg/day) and aspirin (325 mg/day) with a trough valproate level of 24.7 ng/ml and a total valproate level of 64.0 ng/ml. Five days after aspirin was discontinued for a procedure, trough valproate levels fell to 3.9 ng/ml and a total valproate level fell to 36.0 ng/ml with no change in divalproex dosing.(6) In a study in 7 healthy males, concurrent diflunisal (250 mg twice daily) increased the unbound fraction of valproic acid (200 mg twice daily) by 20%. The area-under-curve (AUC) of 3-oxo-valproic acid increased by 35%. There were no effects on diflunisal levels.(7)	DEPAKOTE, DEPAKOTE ER, DEPAKOTE SPRINKLE, DIVALPROEX SODIUM, DIVALPROEX SODIUM ER, SODIUM VALPROATE, VALPROATE SODIUM, VALPROIC ACID
SSRIs; SNRIs/Selected NSAIDs; Aspirin SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Serotonin release by platelets plays a role in hemostasis.(1,2) The increased risk of bleeding may be a result of a decrease in serotonin reuptake by platelets. CLINICAL EFFECTS: Concurrent use of a selective serotonin reuptake inhibitor(1-7,13) or a serotonin-norepinephrine reuptake inhibitor(8-10) and a NSAID may result in bleeding. PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with multiple disease-associated factors (e.g. thrombocytopenia, advanced liver disease). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g., anticoagulants, antiplatelets, or corticosteroids. Risk of GI bleed may be increased in patients who are of older age, in poor health status, or who use alcohol or smoke. Risk may also be increased with longer duration of NSAID use and prior history of peptic ulcer disease and/or GI bleeding. Renal impairment has been associated with an elevated risk of GI bleed in patients on SSRIs.(15) PATIENT MANAGEMENT: Selective serotonin reuptake inhibitors(1-7,13) or serotonin-norepinephrine reuptake inhibitors(8-10) and NSAIDs should be used concurrently with caution. Patients should be warned about the increased risk of bleeding and be educated about signs and symptoms of bleeding.(1-11,13) If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. Discontinue anti-platelet agents in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. DISCUSSION: In a retrospective review of 5 years of data from the Pharmaco-Epidemiologic Prescription Database, hospitalizations for upper gastro-intestinal bleeding in antidepressant users were compared to those in non-antidepressant users. The risk of a bleed in a patient using an NSAID only based on an observed-expected ratio was 4.5 and in a patient using low-dose aspirin only was 2.5. Concurrent use of a selective serotonin reuptake inhibitor with NSAIDs or low-dose aspirin increased the risk of bleeding to 12.2 and 5.2, respectively.(11) In another study, there were 16 cases of upper gastrointestinal bleeding in patients receiving concurrent therapy with selective serotonin reuptake inhibitors and NSAIDs. Adjusted relative risk of bleeding with NSAIDs, selective serotonin reuptake inhibitors, or both were 3.7, 2.6, or 15.6, respectively.(12)	CELEXA, CITALOPRAM HBR, CYMBALTA, DESVENLAFAXINE ER, DESVENLAFAXINE SUCCINATE ER, DRIZALMA SPRINKLE, DULOXETINE HCL, DULOXICAINE, EFFEXOR XR, ESCITALOPRAM OXALATE, FETZIMA, FLUOXETINE DR, FLUOXETINE HCL, FLUVOXAMINE MALEATE, FLUVOXAMINE MALEATE ER, LEXAPRO, OLANZAPINE-FLUOXETINE HCL, PAROXETINE CR, PAROXETINE ER, PAROXETINE HCL, PAROXETINE MESYLATE, PAXIL, PAXIL CR, PRISTIQ, PROZAC, SAVELLA, SERTRALINE HCL, TRINTELLIX, VENLAFAXINE BESYLATE ER, VENLAFAXINE HCL, VENLAFAXINE HCL ER, VIIBRYD, VILAZODONE HCL, ZOLOFT
Aspirin (for Cardioprotection)/Selected NSAIDs SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Some non-steroidal anti-inflammatory agents (NSAIDs) are reversible inhibitors of cyclooxygenase and aspirin is an irreversible inhibitor. If these NSAIDs are given before aspirin, the aspirin will not be able to bind to the cyclooxygenase site, which will result in a lack of effect. CLINICAL EFFECTS: The antiplatelet and cardioprotective effect of aspirin may be decreased with the concurrent use of some NSAIDs, particularly during the washout period of the NSAID. PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: Consideration should be given to use of an NSAID that does not interfere with the antiplatelet effect of aspirin, or a non-NSAID analgesic if appropriate. If an NSAID must be used, cardioprotective doses of aspirin should be administered before taking any NSAIDs. Single doses of ibuprofen should be given at least 8 hours before or at least 2 hours after immediate release aspirin. The administration of other NSAIDs should be separated from aspirin by at least 2 hours. DISCUSSION: The cardioprotective effect from aspirin is based on the antiplatelet effects. The irreversible inhibition of cyclooxygenase mediates the antiplatelet effects. Administration of a reversible inhibitor or cyclooxygenase blocks the irreversible effect of aspirin on the platelets. This effect has been seen with celecoxib, flufenamic acid, ibuprofen, indomethacin, naproxen, nimesulide, oxaprozin, piroxicam, and tiaprofenic acid but not with diclofenac, etoricoxib, ketorolac, meloxicam, or sulindac. In a study of 80 healthy volunteers, aspirin antiplatelet activity, measured by % thromboxane B2 inhibition (TxB2), was decreased when naproxen 220 mg daily was given simultaneously with or 30 minutes before aspirin 81 mg daily for 10 days (98.7% aspirin alone vs 93.1% and 87.7% naproxen and aspirin). The interaction persisted at least 1 day following discontinuation of naproxen but was normalized by the 3rd day. In a nationwide cohort study, patients were evaluated for thromboembolic cardiovascular and clinically relevant bleeding events with concurrent antithrombotic and ongoing NSAID treatment. A total of 108,232 patients were followed for a mean of 2.3 +/- 1.8 years after diagnosis of myocardial infarction. Concomitant NSAID treatment significantly increased the risk for cardiovascular events (hazard ratio (HR) 6.96; 95% CI 6.24 - 6.77; p<0.001) and bleeding events (HR 4.08; 95% CI 3.51 - 4.73; p<0.001) compared to no NSAID treatment. NSAIDs were further evaluated and revealed the use of celecoxib (HR: 4.65; 95% CI: 3.17 to 6.82; p < 0.001, and 3.44; 95% CI: 2.20 to 5.39; p < 0.001, respectively) and meloxicam (HR: 3.03; 95% CI: 1.68 to 5.47; p < 0.001, and 2.80; 95% CI: 1.40 to 5.60; p < 0.001, respectively) had the lowest risk for cardiovascular and bleeding events, receptively.

Apixaban/Aspirin (Less Than or Equal To 100 mg) SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Additive effects on hemostasis.(1-4) CLINICAL EFFECTS: Concurrent use of apixaban with aspirin may increase the risk of bleeding.(1-4) PREDISPOSING FACTORS: Factors associated with an increase risk for bleeding may include renal impairment, concomitant use of P-glycoprotein inhibitors, patient age greater than 74 years, coexisting conditions (e.g. recent trauma) or use of drugs (e.g. NSAIDs) associated with bleeding risk, and patient weight less than 50 kg.(5-7) The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs). PATIENT MANAGEMENT: Monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. DISCUSSION: Concurrent apixaban and aspirin (325 mg daily) resulted in no pharmacokinetic or pharmacodynamic interactions.(1) In a clinical trial examining the use of apixaban in atrial fibrillation, concurrent use of aspirin increased risk of major bleeding with apixaban from 1.8% per year to 3.4% per year and increased the bleeding risk with warfarin from 2.7% per year to 4.6% per year. Concomitant dual antiplatelet therapy was used in 2.1% of patients.(3,4) In a clinical trial examining the use of apixaban in high-risk post acute coronary syndrome patients with multiple cardiac and non-cardiac comorbidities, who received ASA or the combination of ASA and clopidogrel, the risk of major bleeding (defined by ISTH -International Society on Thrombosis and Haemostasis criteria) was increased for apixaban (5.13% per year) compared to placebo (2.04% per year).(3,4) A meta-analysis of 9 studies identified 13,459 patients taking direct oral anticoagulants (DOACs), 1,692 of whom also took an antiplatelet agent. Of the patients on antiplatelet agents, 1,254 took aspirin while the rest was unspecified. Most of the trials restricted patients to use of low-dose aspirin, with the highest allowable dose being 165 mg/day. The use of DOACs with antiplatelet agents was associated with an increased risk of major bleeding (OR 1.89; 95% CI, 1.04-3.44) and clinically relevant non-major bleeding (OR 1.82; 95% CI, 1.50-2.22). There was no difference between groups in the efficacy outcome of symptomatic recurrent venous thromboembolism (VTE) or VTE-related death.(8)	ELIQUIS
Dabigatran/Aspirin (Less Than or Equal To 100 mg) SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Additive effects on hemostasis.(1-3) CLINICAL EFFECTS: Concurrent use of dabigatran with aspirin may increase the risk of bleeding.(1-3) PREDISPOSING FACTORS: Factors associated with an increase risk for bleeding may include renal impairment, concomitant use of P-glycoprotein inhibitors, patient age greater than 74 years, coexisting conditions (e.g. recent trauma) or use of drugs (e.g. NSAIDs) associated with bleeding risk, and patient weight less than 50 kg.(1-3) The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulants/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs). PATIENT MANAGEMENT: Monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. DISCUSSION: A Phase II study in patients with atrial fibrillation examined the effects of dabigatran and concurrent aspirin on the risk of major bleeds. Concurrent use of aspirin and dabigatran etexilate (150 mg twice daily) increased the risk for any bleeding from 12 % to 18 % and 24 % with 81 mg and 325 mg ASA, respectively, when compared to dabigatran alone.(3) In the RE-DUAL PCI trial, patients were randomly assigned to one of three treatments: (A) dual therapy with dabigatran 110 mg twice daily plus either clopidogrel or ticagrelor, (B) dual therapy with dabigatran 150 mg twice daily plus either clopidogrel or ticagrelor, or (C) triple therapy with warfarin (goal INR 2-3) plus aspirin (less than or equal to 100 mg daily) plus either clopidogrel or ticagrelor. The incidence of the first major or clinically relevant non-major (CRNM) bleeding event was 15.4% in group A compared with 26.9% in group C (hazard ratio, 0.52; 95% CI 0.42 to 0.63; p<0.001 for noninferiority; p<0.001 for superiority) and 20.2% in group B compared to 25.7% in corresponding group C (hazard ratio, 0.72; 95% CI 0.58 to 0.88; p<0.001 for noninferiority). Major bleeding as defined by Thrombolysis in Myocardial Infarction (TIMI) criteria, the rate was lower in both dual-therapy groups than in the triple-therapy group: 1.4% in group A compared to 3.8% in group C (hazard ratio, 0.37; 95% CI 0.2 to 0.68; p=0.002) and 2.1% in group B compared to 3.9% in corresponding group C (hazard ratio, 0.51; 95% CI 0.28 to 0.93; p=0.03). Incidence of composite efficacy end point of thromboembolic events (myocardial infarction, stroke, or systemic embolism), death, or unplanned revascularization was 13.7% in groups A and B compared to 13.4% in group C (hazard ratio, 1.04; 95% CI 0.84 to 1.29; p=0.005 for noninferiority).(4) A meta-analysis of 9 studies identified 13,459 patients taking direct oral anticoagulants (DOACs), 1,692 of whom also took an antiplatelet agent. Of the patients on antiplatelet agents, 1,254 took aspirin while the rest was unspecified. Most of the trials restricted patients to use of low-dose aspirin, with the highest allowable dose being 165 mg/day. Compared with DOACs alone, the use of DOACs with antiplatelet agents was associated with an increased risk of major bleeding (OR 1.89; 95% CI, 1.04-3.44) and CRNM bleeding (OR 1.82; 95% CI, 1.50-2.22). There was no difference between groups in the efficacy outcome of symptomatic recurrent venous thromboembolism (VTE) or VTE-related death.(5)	DABIGATRAN ETEXILATE, PRADAXA
Methotrexate (Oncology-Injection)/Aspirin (<=330 mg) SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Salicylates may inhibit the renal tubular excretion of methotrexate. CLINICAL EFFECTS: The concurrent use of methotrexate and salicylates may result in an increase in the therapeutic and toxic effects of methotrexate, leading to increased risk of severe neurotoxicity, stomatitis, and myelosuppression, including neutropenia. PREDISPOSING FACTORS: Risk factors for methotrexate toxicity include: - High-dose oncology regimens - Anti-inflammatory doses of aspirin/salicylates - Impaired renal function, ascites, or pleural effusions PATIENT MANAGEMENT: US manufacturer prescribing information for methotrexate states nonsteroidal anti-inflammatory drugs including aspirin should not be administered prior to or concomitantly with high doses of methotrexate. If concurrent therapy is warranted, methotrexate plasma levels should be monitored and patients should be observed for methotrexate toxicity. The dosage of methotrexate may need to be adjusted. Use caution when administering higher doses of salicylates with lower doses of methotrexate. Salicylate doses > or = 2 grams per day have been associated with hepatic impairment or impaired renal elimination of methotrexate. It would be prudent to avoid high-dose aspirin, especially near the time of methotrexate dosage in patients receiving intermittent methotrexate therapy, and in patients with renal impairment. DISCUSSION: Several studies and case reports have reported increased and prolonged methotrexate levels in patients receiving concurrent aspirin. One study noted an effect with average weekly doses of methotrexate of 16.6 mg, but not weekly doses of 7.5 mg. Decreased renal function has also been reported with the combination. Single ingredient aspirin or buffered aspirin products with strengths < or = to 325 mg or formulations which are associated with once daily use for cardiovascular protection are included in this interaction. Other aspirin and salicylate products are linked to higher severity level interactions.	METHOTREXATE, METHOTREXATE SODIUM
Ibrutinib/Selected Anticoagulants; Antiplatelets SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Ibrutinib administration lowers platelet count in the majority of patients.(1,2) In addition, ibrutinib has been shown to inhibit collagen-mediated platelet aggregation.(3-4) Bleeding has been reported with the use of ibrutinib,(1-4) anticoagulants, or antiplatelets alone. CLINICAL EFFECTS: Concurrent use of ibrutinib with either anticoagulants or antiplatelets may increase the risk of hemorrhage. PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs). PATIENT MANAGEMENT: The Canadian product monograph for ibrutinib recommends concurrent use with anticoagulants or antiplatelets should be approached with caution. If therapeutic anticoagulation is required, consider temporarily withholding ibrutinib therapy until stable anticoagulation in achieved.(2) The US prescribing information for ibrutinib states patients receiving concurrent therapy with ibrutinib and anticoagulants and/or antiplatelets should be closely monitored for changes in platelet count or in International Normalized Ratio (INR). Carefully weigh the risks vs. benefits of concurrent therapy in patients with significant thrombocytopenia. If a bleeding event occurs, follow manufacturer instructions for ibrutinib dose adjustment.(1) If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory tests (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated or discontinued. Contact the prescriber before initiating, altering the dose or discontinuing either drug. DISCUSSION: Bleeding has been reported with ibrutinib alone.(1-3) Across 27 clinical trials, grade 3 or higher bleeding events, e.g. subdural hematoma, gastrointestinal bleeding or hematuria, have occurred in up to 4% of patients, with 0.4% fatality. Grade 3 or 4 thrombocytopenia occurred in 5-19% of patients. Bleeding events of any grade occurred in 39% of patients treated with ibrutinib.(1) Concurrent use of anticoagulants or antiplatelets has been reported to increase the risk for major bleeding. In clinical trials, major bleeding occurred in 3.1% of patients taking ibrutinib without concurrent anticoagulants or antiplatelets, 4.4% of patients on concurrent antiplatelets with or without anticoagulants, and 6.1% of patients on concurrent anticoagulants with or without antiplatelets.(1) In an open-label, phase 2 trial of patients with relapsed/refractory mantle cell lymphoma on ibrutinib, 61 patients (55%) on concurrent anticoagulants or antiplatelets had a higher rate of bleeding (69% any grade, 8% grade 3-4) than patients not on anticoagulants or antiplatelets (28% any grade, 4% grade 3-4).(5) A retrospective trial found a hazard ratio of 20 (95% CI, 2.1-200) for patients on ibrutinib with concurrent anticoagulants and antiplatelets. There was a trend towards an increased bleeding risk in patients on either anticoagulants or antiplatelets, but this was not statistically significant on multivariate analysis.(6) A case report of 2 patients with chronic lymphocytic leukemia (CLL) on ibrutinib and dabigatran demonstrated no stroke nor bleeding events during the mean 11.5 month follow-up.(7) A case report of 4 patients with lymphoproliferative disease on concurrent dabigatran and ibrutinib demonstrated no stroke nor major bleeding events. 1 patient experienced grade 2 conjunctival hemorrhage whilst on both ibrutinib and dabigatran. The anticoagulant was withheld and successfully re-initiated at a lower dose with no further bleeding events.(8)	IMBRUVICA
Selected Anticoagulants (Vitamin K antagonists)/Aspirin (Less Than or Equal To 100 mg) SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Multiple processes are involved: 1)Aspirin is an irreversible platelet inhibitor. It impairs platelet function, resulting in prolonged bleeding time. 2) Aspirin may cause gastrointestinal (GI) bleeding due to irritation. CLINICAL EFFECTS: The concurrent use of anticoagulants and aspirin leads to blockade of two distinct coagulation pathways and may increase the risk for bleeding. PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs). PATIENT MANAGEMENT: Weigh the patient specific benefits versus risk for concomitant use. If concurrent therapy of low dose aspirin and an anticoagulant is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin and/or hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; severe headache, acute abdominal or joint pain and/or swelling. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated or discontinued. Contact the prescriber before initiating, altering the dose or discontinuing either drug. DISCUSSION: This interaction has been reported between aspirin and warfarin and between aspirin and dicumarol. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated, altered, or discontinued. A self-controlled case study of 1,622 oral anticoagulant-precipitant drug pairs were reviewed and found 14% of drug pairs were associated with a statistically significant elevated risk of thromboembolism. Concurrent use of warfarin and aspirin resulted in a ratio of rate ratios (95% CI) of 2.13 (1.72-2.64). A large systematic review was performed on 72 warfarin drug-drug interactions studies that reported on bleeding, thromboembolic events, or death. Most studies were retrospective cohorts. A meta-analysis of 38 of those studies found a higher rate of clinically significant bleeding in patients on warfarin and antiplatelets (OR=1.74; 95% CI 1.56-1.94). Increased bleeding risk was also seen in subgroup analyses with aspirin (OR=1.50; 95% CI 1.29-1.74), clopidogrel (OR=3.55; 95% CI 2.78-4.54), and aspirin plus clopidogrel or ticlopidine (OR=2.07, 95% CI 1.33-3.21).(16)	ANISINDIONE, DICUMAROL, JANTOVEN, PHENINDIONE, WARFARIN SODIUM
Rivaroxaban/Aspirin (Less Than or Equal To 100 mg) SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Additive effects on hemostasis.(1) CLINICAL EFFECTS: Concurrent use of rivaroxaban with antiplatelets may increase the risk of bleeding.(1) PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (NSAIDs). PATIENT MANAGEMENT: Monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or blood pressure and promptly evaluate patients with any symptoms. Discontinue rivaroxaban in patients with active pathological bleeding.(2) The US manufacturer states concurrent use of rivaroxaban 2.5 mg and aspirin 81 mg is an approved indication for the reduction of cardiovascular events in patients with coronary artery disease (CAD) or peripheral artery disease (PAD). Discontinue rivaroxaban in patients with active pathological bleeding. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. DISCUSSION: In the ROCKET AF trial, concomitant aspirin use (almost exclusively at less than or equal to to 100 mg daily) was identified as an independent risk factor for bleeding.(1-2) In a single dose study, there were no pharmacokinetic or pharmacodynamic interactions between rivaroxaban and aspirin.(1) A self-controlled case study of 1,622 oral anticoagulant-precipitant drug pairs were reviewed and found 14% of drug pairs were associated with a statistically significant elevated risk of thromboembolism. Concurrent use of rivaroxaban and aspirin resulted in a ratio of rate ratios (95% CI) of 2.19 (1.21-2.95).(3) A meta-analysis of 9 studies identified 13,459 patients taking direct oral anticoagulants (DOACs), 1,692 of whom also took an antiplatelet agent. Of the patients on antiplatelet agents, 1,254 took aspirin while the rest was unspecified. Most of the trials restricted patients to use of low-dose aspirin, with the highest allowable dose being 165 mg/day. The use of DOACs with antiplatelet agents was associated with an increased risk of major bleeding (OR 1.89; 95% CI, 1.04-3.44) and clinically relevant non-major bleeding (OR 1.82; 95% CI, 1.50-2.22). There was no difference between groups in the efficacy outcome of symptomatic recurrent venous thromboembolism (VTE) or VTE-related death.(4) In the VOYAGER PAD trial, 6564 patiens were enrolled with peripheral artery disease (PAD). Rivaroxaban 2.5 mg twice daily in combination with aspirin 81 mg was found to reduce the total number of arterial and venous events by 23% compared to aspirin 81 mg alone. The combination increased the risk of bleeding. If 10,000 patients were treated, 181 cardiovascular events would be prevented at a cost of 29 bleeding events, a 6:1 benefit to risk ratio.(5) The COMPASS trial enrolled 27,395 patients with PAD or coronary artery disease (CAD) to determine whether combined rivaroxaban and aspirin reduced the risk of cardiovascular events more than aspirin alone. The combination of rivaroxaban 2.5 mg twice daily and aspirin 100 mg daily reduced mortality by 18% compared to aspirin alone.(6) A secondary analysis of incidence and predictors of major gastrointestinal (GI) bleeding in patients enrolled in the COMPASS trial demonstrated that compared to the use of aspirin (100 mg daily) alone, use of rivaroxaban (5 mg twice daily) significantly increased the odds of overall GI bleeding (OR 1.44; 95% CI 1.05-1.99), and the use of the combination of rivaroxaban (2.5 mg twice daily) and aspirin (100 mg daily) further increased the odds (OR 2.17; 95% CI 1.61-2.93).(7)	RIVAROXABAN, XARELTO
Edoxaban/Aspirin (Less Than or Equal To 100 mg) SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Edoxaban and aspirin have additive effects on hemostasis.(1) In addition, aspirin doses greater than or equal to 325 mg daily increase edoxaban exposure.(1) CLINICAL EFFECTS: Concurrent use of edoxaban with aspirin may increase the risk of bleeding compared to either agent alone.(1) PREDISPOSING FACTORS: Bleeding risk may be increased in patients with renal impairment and in patients greater than 75 years of age.(1) Use of multiple agents which affect hemostasis increases the risk for bleeding. The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs). PATIENT MANAGEMENT: Patients requiring concurrent therapy with edoxaban and aspirin should be closely monitored for signs of bleeding. Edoxaban and aspirin at dosages of 100 mg or less may be coadministered.(2,3) Monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin and/or hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. Discontinue edoxaban in patients with active bleeding. DISCUSSION: Concomitant use of edoxaban and antiplatelet agents may increase the risk of bleeding. In edoxaban clinical trials concomitant use of low dose aspirin (less than or equal to 100 mg daily), thienopyridines, and NSAIDs was permitted and resulted in increased rates of clinically relevant bleeding. The rates of major bleeding on edoxaban and warfarin were generally consistent among subgroups. Bleeding rates appeared higher in both treatment arms (edoxaban and warfarin) in patients taking aspirin. Co-administration of aspirin (100 mg or 325 mg) and edoxaban increased bleeding time relative to that seen with either drug alone.(1) About 30% of the population in ENGAGE-AF received concomitant therapy with aspirin because of co-morbid conditions. While aspirin is known to increase risk for bleeds and the annualized event rate for major bleeds was higher than that in patients not receiving aspirin (3.87% vs. 2.13%), the risk for bleeds in patients receiving edoxaban 60 mg on a background of aspirin was lower than that for warfarin on a background of aspirin (HR 0.78 (95%CI 0.65,0.94). Based on these data no dose adjustments/contraindications are required.(4) Edoxaban and aspirin at dosages of 100 mg or less may be coadministered.(2,3) A meta-analysis of 9 studies identified 13,459 patients taking direct oral anticoagulants (DOACs), 1,692 of whom also took an antiplatelet agent. Of the patients on antiplatelet agents, 1,254 took aspirin while the rest was unspecified. Most of the trials restricted patients to use of low-dose aspirin, with the highest allowable dose being 165 mg/day. The use of DOACs with antiplatelet agents was associated with an increased risk of major bleeding (OR 1.89; 95% CI, 1.04-3.44) and clinically relevant non-major bleeding (OR 1.82; 95% CI, 1.50-2.22). There was no difference between groups in the efficacy outcome of symptomatic recurrent venous thromboembolism (VTE) or VTE-related death.(5)	SAVAYSA
Mifepristone (Cushing)/Anticoagulants; Antiplatelets SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Mifepristone is an antagonist at the progesterone receptor which can result in endometrium thickening, cystic dilatation of endometrial glands, or excessive vaginal bleeding. Concurrent use with anticoagulants or antiplatelets may further increase risk. CLINICAL EFFECTS: The concurrent use of mifepristone with anticoagulants or antiplatelets may result in endometrium thickening, cystic dilatation of endometrial glands, or excessive vaginal bleeding. PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs). PATIENT MANAGEMENT: The manufacturer of mifepristone states that mifepristone should be used with caution in patients receiving concurrent anticoagulant or antiplatelet therapy.(1) If concurrent therapy is deemed medically necessary, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. Women experiencing vaginal bleeding during concurrent use should be referred to a gynecologist for further evaluation. DISCUSSION: The manufacturer of mifepristone states that mifepristone should be used with caution in patients receiving concurrent anticoagulant or antiplatelet therapy.(1)	KORLYM, MIFEPRISTONE
Aliskiren/NSAIDs; Salicylates SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: The exact mechanism is unknown. It is believed to be related to inhibition of prostaglandin synthesis by the NSAIDs. Use of an NSAID in combination with aliskiren, whose hypotensive effects may be related to the increase in hypotensive prostaglandins, may negate any decrease in blood pressure. CLINICAL EFFECTS: Concurrent use of aliskiren with NSAIDs may result in decreased antihypertensive effects. In patients with existing renal impairment, the use of these agents together may also result in further deterioration of renal clearance caused by renal hypoperfusion. PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: Patients maintained on aliskiren should be monitored for a loss of blood pressure control and a change in renal function if an NSAID is added to their regimen. Patients receiving concurrent therapy may require higher doses of aliskiren. If blood pressure control cannot be achieved or if the patient's renal function deteriorates, the NSAID may need to be discontinued. Patients should be monitored for hypotension if NSAIDs are withdrawn from concurrent aliskiren therapy. DISCUSSION: Indomethacin has been shown to inhibit the antihypertensive effect of captopril, cilazapril, enalapril, losartan, perindopril, and valsartan. Ibuprofen has been shown to decrease the antihypertensive effects of captopril. Two separate case reports describe individuals suspected of ACEI-associated angioedema precipitated by NSAIDs. Both cases reported symptom resolution after cessation of the NSAID. Studies have shown that sulindac does not affect the antihypertensive effects of captopril and enalapril.	ALISKIREN, TEKTURNA
Dichlorphenamide/Aspirin (Less Than or Equal To 325 mg) SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Carbonic anhydrase inhibitors (eg, acetazolamide) may reduce blood pH, causing a shift of salicylates from plasma into tissues (eg, central nervous system).(1) Alternatively, toxicity may be due to salicylate-induced displacement of the carbonic anhydrase inhibitor from its protein binding sites and inhibition of renal tubular secretion. CLINICAL EFFECTS: An increase in the pharmacologic effects of salicylates with possible toxicity may occur. Anorexia, tachypnea, lethargy, and coma have been reported.(1) PREDISPOSING FACTORS: High doses of salicylates, low body weight. PATIENT MANAGEMENT: The concurrent use of high-dose aspirin or other salicylates with dichlorphenamide is contraindicated. If it is necessary to administer a low-dose salicylate concurrently, use the lowest dose possible or replace it with a non-salicylate anti-inflammatory agent. Monitor salicylate levels and serum bicarbonate concentrations, and monitor the patient for symptoms of toxicity. Adjust the dose as needed.(1) DISCUSSION: An 8-year-old boy with unimpaired renal and hepatic function was found to have developed metabolic acidosis after treatment for glaucoma and joint pain with a combination of aloxiprin 3.6 gram daily and dichlorphenamide 25 mg three times daily. His symptoms resolved after discontinuation of both aloxiprin and dichlorphenamide and did not recur on subsequent therapy with naproxen and dichlorphenamide.(2) A 75-year old woman taking dichlorphenamide 100 mg to 150 mg daily for therapy of glaucoma and high doses of aspirin (975 mg 4 to 5 times daily) for arthritis developed severe acid-base imbalance and salicylate intoxication. The patient did not exhibit ill effects when taking high aspirin doses without dichlorphenamide.(3)	DICHLORPHENAMIDE, KEVEYIS, ORMALVI
Icosapent Ethyl/Anticoagulant;Antiplatelet;Thrombolytic SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: In vitro data suggests that fish oils can competitively inhibit cyclooxygenase which decreases synthesis of thromboxane A1 leading to a decrease in platelet aggregation.(1) CLINICAL EFFECTS: Concurrent use of anticoagulant, antiplatelet, or thrombolytic agents increase bleeding risks. PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs). PATIENT MANAGEMENT: If concurrent therapy is deemed medically necessary, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory tests (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated or discontinued. Contact the prescriber before initiating, altering the dose or discontinuing either drug. DISCUSSION: Specific studies with icosapent ethyl and affects on bleeding risk have not been conducted. Concurrent use of anticoagulant, antiplatelet, or thrombolytic agents may increase bleeding risks by impairing platelet function and prolonging bleeding time.(1) Several case reports have shown increased bleeding time and an increased risk of adverse effects from concurrent therapy.(2,3,4) A randomized placebo controlled study of 40 people taking omega-3 fatty acids and oral anticoagulants showed a significant prolongation in bleeding time.(5)	ICOSAPENT ETHYL, VASCEPA
Fruquintinib; Surufatinib/Anticoagulants; Antiplatelets SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Bleeding has been reported with the use of fruquintinib and surufatinib.(1,2) CLINICAL EFFECTS: Concurrent use of fruquintinib or surufatinib with either anticoagulants or antiplatelets may increase the risk of hemorrhage.(1,2) PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs). PATIENT MANAGEMENT: Patients receiving concurrent therapy with fruquintinib and anticoagulants and/or antiplatelets should be closely monitored for changes in platelet count or in International Normalized Ratio (INR). If a serious bleeding event occurs, the manufacturer recommends permanent discontinuation of fruquintinib.(1) Patients receiving concurrent therapy with surufatinib and anticoagulants and/or antiplatelets should be closely monitored for changes in platelet count or in INR.If a serious bleeding event occurs, the manufacturer recommends permanent discontinuation of surufatinib.(2) If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory tests (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated or discontinued. Contact the prescriber before initiating, altering the dose or discontinuing either drug. DISCUSSION: Bleeding has been reported with fruquintinib in three randomized, double-blinded, placebo-controlled clinical trials. The incidence of grade 1 and grade 2 bleeding events was 28.2%, including gastrointestinal bleeding (10.9%), hematuria (10.6%), and epistaxis (7.5%). The incidence of grade 3 or higher bleeding events was 2.1% and included gastrointestinal bleeding (1.6%) and hemoptysis (0.5%).(1) Bleeding has been reported with surufatinib in clinical trials. Grade 1 and 2 bleeding events included gastrointestinal bleeding, blood in the urine, and gum bleeding. The incidence of grade 3 or greater bleeding events was 4.5%, including gastrointestinal hemorrhage (1.9%), and cerebral hemorrhage (1.1%). Fatalities due to bleeding were reported in 0.3% of patients. The incidence of permanent discontinuation due to bleeding was 2.6% and the incidence of suspension of surufatinib due to bleeding was 3.8%.(2)	FRUZAQLA
Plasminogen/Anticoagulants; Antiplatelets SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Bleeding has been reported with the use of plasminogen.(1) CLINICAL EFFECTS: Concurrent use of plasminogen with either anticoagulants or antiplatelets may increase the risk of active bleeding during plasminogen therapy, including bleeding from mucosal disease-related lesions that may manifest as gastrointestinal (GI) bleeding, hemoptysis, epistaxis, vaginal bleeding, or hematuria.(1) PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs). PATIENT MANAGEMENT: Patients receiving concurrent therapy with plasminogen and anticoagulants and/or antiplatelets should be closely monitored during plasminogen therapy for active bleeding from mucosal disease-related lesions, including GI bleeding, hemoptysis, epistaxis, vaginal bleeding, or hematuria.(1) Prior to initiation of treatment with plasminogen, confirm healing of lesions or wounds suspected as a source of a recent bleeding event. Monitor patients during and for 4 hours after infusion when administering plasminogen with concurrent anticoagulants, antiplatelet drugs, or other agents which may interfere with normal coagulation.(1) If patient experiences uncontrolled bleeding (defined as any gastrointestinal bleeding or bleeding from any other site that persists longer than 30 minutes), seek emergency care and discontinue plasminogen immediately.(1) If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory tests (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated or discontinued. Contact the prescriber before initiating, altering the dose or discontinuing either drug. DISCUSSION: Plasminogen has not been studied in patients at an increased risk of bleeding. Bleeding has been reported with plasminogen in a two single-arm, open-label clinical trials as well as in compassionate use programs. The incidence of hemorrhage in patients with Plasminogen Deficiency Type 1 was 16% (3/19 patients).(1) One of the bleeding events occurred two days after receiving the second dose of plasminogen in a patient with a recent history of GI bleeding due to gastric ulcers. The patient received plasminogen through a compassionate use program and the dose was 6.6 mg/kg body weight every 2 days. Endoscopy showed multiple ulcers with one actively bleeding ulcer near the pylorus.(1)	RYPLAZIM
Tisotumab/Anticoagulants; Antiplatelets SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Bleeding, including hemorrhage, has been reported with the use of tisotumab.(1) CLINICAL EFFECTS: Concurrent use of tisotumab with either anticoagulants, antiplatelets, or NSAIDs may increase the risk of hemorrhage.(1) PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs). PATIENT MANAGEMENT: Patients receiving concurrent therapy with tisotumab and anticoagulants, antiplatelets, and/or NSAIDs should be closely monitored for signs and symptoms of bleeding and changes in platelet count or International Normalized Ratio (INR). For patients experiencing pulmonary or central nervous system (CNS) hemorrhage, permanently discontinue tisotumab. For grade 2 or greater hemorrhage in any other location, withhold until bleeding has resolved, blood hemoglobin is stable, there is no bleeding diathesis that could increase the risk of continuing therapy, and there is no anatomical or pathologic condition that can increase the risk of hemorrhage. After resolution, either resume treatment or permanently discontinue tisotumab.(1) If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory tests (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated or discontinued. Contact the prescriber before initiating, altering the dose or discontinuing either drug. DISCUSSION: Hemorrhage occurred in 62% of patients with cervical cancer treated with tisotumab across clinical trials. The most common all grade hemorrhage adverse reactions were epistaxis (44%), hematuria (10%), and vaginal hemorrhage (10%). Grade 3 hemorrhage occurred in 5% of patients.(1)	TIVDAK
Sparsentan/NSAIDs; Salicylates SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Sparsentan is an endothelin and angiotensin II receptor antagonist.(1) Angiotensin II receptor blockers can cause vasodilation of the efferent renal arteriole which may result in decreased glomerular filtration rate. NSAIDs inhibit prostaglandin synthesis which can lead to afferent arteriolar vasoconstriction. CLINICAL EFFECTS: Concurrent use of sparsentan with NSAIDs (including selective COX-2 inhibitors) may result in renal hypoperfusion and deterioration of renal clearance, including possible acute kidney injury (AKI). These effects are usually reversible.(1) PREDISPOSING FACTORS: Patients older than 75 years old, with renal artery stenosis, chronic kidney disease, severe congestive heart failure, or volume depletion (including from diuretic use and dehydration) may be at greater risk for AKI.(1-3) PATIENT MANAGEMENT: Monitor for signs of worsening renal function if an NSAID (including selective COX-2 inhibitors) is used concurrently with sparsentan. If renal function deteriorates, the NSAID may need to be discontinued.(1) DISCUSSION: In a computational study, the risk of AKI using triple therapy with a diuretic, renin-angiotensin system (RAS) inhibitor, and NSAID was assessed. The study found the following factors may increase an individual's susceptibility to AKI: low water intake, drug sensitivity, greater than 75 years of age, and renal impairment.(2,3) In an observational study, current use of a triple therapy combination was associated with an increased rate of acute kidney injury (rate ratio (RR) 1.31, 95% confidence interval (CI) 1.12-1.53). The highest risk of AKI associated with triple therapy were observed in the first 30 days of use (RR 1.82, CI 1.35-2.46).(4)	FILSPARI
NSAIDs; Salicylates/Minoxidil SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Oral minoxidil functions as a direct-acting peripheral vasodilator, lowering elevated systolic and diastolic blood pressure by reducing resistance in peripheral blood vessels. This triggers a compensatory increase in cardiac output and renin secretion and results in sodium and water retention. NSAIDs inhibit prostaglandin synthesis and also result in sodium and water retention.(1,2) CLINICAL EFFECTS: The risk of heart failure may increase with oral minoxidil and NSAIDs due to their combined effects on blood vessel dilation, fluid retention, and altered sodium balance. Minoxidil efficacy may be compromised.(1,2) PREDISPOSING FACTORS: Higher doses of oral minoxidil have been associated with serious adverse events, including hypotensive syncope, pericarditis, pericardial effusion, and myocardial infarction.(1-5) PATIENT MANAGEMENT: Closely monitor body weight, fluid and electrolyte balance, and blood pressure when using oral minoxidil and NSAIDs concurrently. Minoxidil tablets should be co-administered with an appropriate diuretic to prevent fluid retention and potential congestive heart failure. A high-ceiling (loop) diuretic is often necessary alongside vigilant monitoring of body weight. Without concurrent diuretic use, minoxidil may lead to the retention of salt and water within a few days.(1,2) DISCUSSION: While the manufacturer of minoxidil does not provide specific recommendations regarding NSAID co-administration, it emphasizes the necessity of combining minoxidil with a beta-blocker to prevent tachycardia and increased myocardial workload. Additionally, concurrent use with a diuretic is recommended to avert serious fluid accumulation and potential congestive heart failure. NSAID labeling warns about fluid retention, edema, an elevated risk of heart failure, and potential drug interactions with beta-blockers and diuretics which can result in a blunting of the antihypertensive and cardiovascular effects of these agents.(1-5)	MINOXIDIL
T Cell Immunotherapies/NSAIDs; Salicylates SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: NSAIDs augment the immune system. Concurrent use with NSAIDs may interfere with the activity of CAR-T cell immunotherapies.(1) CLINICAL EFFECTS: NSAIDs may decrease the efficacy of CAR-T cell immunotherapies.(1) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: NSAIDs should be used with caution with or after CAR-T cell immunotherapy.(1) DISCUSSION: An in vitro study showed aspirin and celecoxib negatively affected CD19.CAR-T cells through their effects on the induction of apoptosis, reduction of activation, and impairment of proliferation.(1)	ABECMA, AMTAGVI, AUCATZYL, BREYANZI, BREYANZI CD4 COMPONENT, BREYANZI CD8 COMPONENT, CARVYKTI, KYMRIAH, TECARTUS, TECELRA, YESCARTA
