Review the full interaction monograph for more information.

Drug Interaction	Drug Names
ACE Inhibitors; ARBs/Lithium SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Angiotensin converting enzyme inhibitors (ACEI) or angiotensin II receptor blocker (ARB)-induced sodium loss or volume depletion may result in decreased renal clearance of lithium.(1) CLINICAL EFFECTS: Concurrent use of ACEI or ARBs may result in elevated lithium levels and lithium toxicity. Lithium has a narrow therapeutic range. Unintended increases in lithium concentrations may lead to lithium toxicity. Early symptoms of lithium toxicity may include: lethargy, muscle weakness or stiffness, new onset or coarsening of hand tremor, vomiting, diarrhea, confusion, ataxia, blurred vision, bradycardia, tinnitus, or nystagmus. Severe toxicity may produce multiple organ dysfunction (e.g. seizures, coma, renal failure, cardiac arrhythmias, cardiovascular collapse) and may be fatal.(1) PREDISPOSING FACTORS: Risk factors for lithium toxicity include: acute renal impairment, chronic renal disease, dehydration, low sodium diet, and concomitant use of multiple medications which may impair renal elimination of lithium (e.g. ACEI, ARBs, NSAIDs, diuretics).(1) Patients who require higher therapeutic lithium levels to maintain symptom control are particularly susceptible to these factors. PATIENT MANAGEMENT: If concurrent therapy cannot be avoided, monitor closely. Evaluate renal function and most recent lithium levels. If renal function is not stable, whenever possible delay initiation of concurrent therapy until renal function is stable. The onset of lithium toxicity due to concomitant therapy with an ACEI or ARB may be delayed for 3-5 weeks.(2) Patients receiving this combination should be observed for signs of lithium toxicity when the ACEI or ARB dose is increased or if additional risk factors for lithium toxicity emerge. If an ACEI or ARB is required in a patient stabilized on lithium therapy, check baseline lithium concentration, consider empirically lowering the lithium dose, then recheck lithium levels 5 to 7 days after ACEI or ARB initiation. Adjust lithium, ACEI or ARB dose as required and continue frequent (e.g. weekly) monitoring of lithium until levels have stabilized. If lithium is to be started in a patient stabilized on an ACEI or ARB, consider starting with a lower lithium dose and titrate slowly as half-life may be prolonged.(1) Monitor lithium concentrations frequently until stabilized on the combination. If an interacting drug is discontinued, the lithium level may fall. Monitor lithium concentration and adjust dose if needed.(1) Counsel patient to assure they know signs and symptoms of lithium toxicity and understand the importance of follow-up laboratory testing. DISCUSSION: Elevated lithium levels and lithium toxicity have been reported during concomitant administration of lithium and an ACEI(3-17) or an ARB(18-20). Other factors, such as dehydration, acute or worsening of chronic renal impairment, or acute changes in sodium intake may increase the occurrence of a clinically important interaction.

Colistimethate/Selected Nephrotoxic Agents SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Colistimethate can cause nephrotoxicity.(1,2) Concurrent administration of other nephrotoxic agents may result in an increased risk of nephrotoxicity.(1) It is suspected that cephalothin interferes with the excretion of colistimethate resulting in enhanced nephrotoxicity.(2,3) CLINICAL EFFECTS: Concurrent use of colistimethate with other nephrotoxic agents may result in additive nephrotoxic effects. PREDISPOSING FACTORS: Factors predisposing to nephrotoxicity include higher cumulative doses of colistimethate, longer treatment duration, hypovolemia, and critical illness. PATIENT MANAGEMENT: Concurrent use of potentially nephrotoxic agents with colistimethate should be avoided.(1,2) If concurrent use is necessary, it should be undertaken with great caution.(1) DISCUSSION: In a case control study of 42 patients on intravenous colistimethate sodium, NSAIDs were identified as an independent risk factor for nephrotoxicity (OR 40.105, p=0.044).(4) In 4 case reports, patients developed elevated serum creatinine and blood urea nitrogen following concurrent colistimethate and cephalothin (3 patients) or when colistimethate followed cephalothin therapy (1 patient).(3) A literature review found that individual nephrotoxic agents, including aminoglycosides, vancomycin, amphotericin, IV contrast, diuretics, ACE inhibitors, ARBs, NSAIDs, and calcineurin inhibitors, were not consistently associated with additive nephrotoxicity when used with colistimethate. However, when multiple agents (at least 2 additional potential nephrotoxins) were used concurrently, there was a significant correlation to colistimethate nephrotoxicity.(5)	COLISTIMETHATE, COLISTIMETHATE SODIUM, COLY-MYCIN M PARENTERAL
Sodium Phosphate Bowel Cleanser/ACE Inhibitors; ARBs 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 angiotensin converting enzyme (ACE) inhibitors, angiotension receptor blockers (ARBs) 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 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, ARBs, and possibly nonsteroidal anti-inflammatory drugs (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
ACE Inhibitors; ARBs/Trimethoprim SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: ACE Inhibitors, Angiotensin Receptor Blockers (ARBs), and trimethoprim have all been proven to increase serum potassium levels. The increase is achieved by reduction in potassium elimination by trimethoprim(1,2) and a decrease in angiotensin activity by ACE Inhibitors and ARBs. The use of these medications in combination can have an additive effect on serum potassium resulting in potentially dangerous levels.(1-5) CLINICAL EFFECTS: Concurrent use of trimethoprim and ACE Inhibitors or Angiotensin Receptor Blockers may result in increased serum potassium levels,(1-5) which may be fatal.(2) PREDISPOSING FACTORS: The interaction may be more significant in elderly patients and patients with renal insufficiency.(1) PATIENT MANAGEMENT: Use trimethoprim with caution in patients maintained on ACE Inhibitors or ARBs. Patients using these medications concurrently should have their serum potassium monitored. In the elderly or renally impaired, alternative antibiotic therapy should be considered. DISCUSSION: In a retrospective review of patients in Ontario maintained on an ACE inhibitor or ARB who were admitted to a hospital for hyperkalemia within 14 days of receiving a prescription for SMX-TMP, amoxicillin, ciprofloxacin, norfloxacin, or nitrofurantion, 371 patients were identified. More than half of the patients with hyperkalemia had received SMX-TMP. Patients receiving SMX-TMP had a 7-fold increased risk of hyperkalemia compared to patients receiving other antibiotics. No risk was found with the other antibiotics.(1) A retrospective review of patients in Ontario maintained on an ACE inhibitor or ARB examined those who died within 7 days of filling an outpatient prescription for amoxicillin, ciprofloxacin, norfloxacin, nitrofurantoin, or SMX-TMP. Patients receiving SMX-TMP had an increased risk of death (adjusted odds ratio 1.38) compared to amoxicillin. Risk was slightly higher at 14 days (adjusted odds ration 1.54). This corresponded to 3 sudden deaths within 14 days per 1000 SMX-TMP prescriptions.(2) A review of nine case reports of hyperkalemia with SMX-TMP found that 2 patients were receiving concurrent ACE inhibitors (enalapril and benazepril). One of these patients had severe hyperkalemia with a peak potassium level of 7.4 mEq/l.(3) Hyperkalemia has also been reported with concurrent SMX-TMP and enalapril(4) and with quinapril.(5)	BACTRIM, BACTRIM DS, PRIMSOL, SULFAMETHOXAZOLE-TRIMETHOPRIM, SULFATRIM, TRIMETHOPRIM, TRIMETHOPRIM MICRONIZED
Aliskiren/ACE Inhibitors; ARBs SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: The exact mechanism is unknown. CLINICAL EFFECTS: In the ALTITUDE study, concurrent use of aliskiren for 18-24 months in patients maintained on either an ACE inhibitor or an ARB resulted in an increase in non-fatal stroke, renal complications, hyperkalemia, and hypotension.(1,2) PREDISPOSING FACTORS: Patients with Type II diabetes and/or renal impairment may be at a higher risk from this combination.(1) PATIENT MANAGEMENT: Novartis no longer recommends the concurrent use of aliskiren with either an ACE inhibitor or an ARB.(1,3) Hypertension regimens of patients receiving concurrent therapy should be re-evaluated.(1) Concurrent use of aliskiren in diabetic patients receiving either an ACE inhibitor or an ARB is contraindicated.(2,4) Avoid the combination in patients with CrCl less than 60 ml/min.(5) DISCUSSION: ALTITUDE was a multinational study designed to evaluate the use of aliskiren for more than 1 year in patients with Type II diabetes and renal impairment, who are known to have a high risk for cardiovascular and renal events. Aliskiren was given with optimal cardiovascular treatment, including an ACE inhibitor or ARB. After 18-24 months of concurrent therapy with aliskiren and either an ACE inhibitor or an ARB, there was an increase in non-fatal stroke, renal complications, hyperkalemia, and hypotension.(1,2)	ALISKIREN, TEKTURNA

There are 9 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
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 (combination of 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.

Angiotensin II Receptor Blocker (ARB)/K+ Sparing Diuretics SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Angiotensin II receptor blockers (ARBs) may decrease the renal excretion of potassium. CLINICAL EFFECTS: Concurrent use of potassium sparing diuretics with an ARB may result in hyperkalemia. PREDISPOSING FACTORS: Impaired renal function; diabetes mellitus. PATIENT MANAGEMENT: Monitor serum potassium and adjust the dosage accordingly in patients receiving concurrent therapy with a potassium sparing diuretic and an ARB. In all patients taking eplerenone who start taking an an ARB, check serum potassium and creatinine levels after 3-7 days of concurrent therapy. DISCUSSION: In a nested case-control study of heart failure patients receiving continuous ACE inhibitor/ARB therapy (n = 1,491,894), the risk of hyperkalemia was significantly associated with spironolactone use (odds ratio (OR) = 13.59; confidence interval (CI) = 11.63-15.88).(20) In a systemic literature review and meta-analysis of 20 randomized controlled studies, it was found that treatment with spironolactone and ACEI/ARB combination therapy compared to ACEI/ARB therapy alone increased the mean serum potassium concentration by 0.19 mEq/L (95% CI, 0.12-0.26 mEq/L).(21) A retrospective cohort study in patients with hypertension, diabetes, and albuminuria between 2008 and 2018 examined the efficacy and safety of mineralocorticoid receptor antagonists eplerenone and spironolactone in combination with ACEI/ARB compared to ACEI/ARB alone. Hyperkalemia was more frequent in combination therapy patients (n=1,282) versus monotherapy (n=5,484) (22.3 vs 10.9 per 100 person-years for combination and monotherapy, respectively; HR = 1.78, 95% CI: 1.42, 2.24).(22) Several studies have indicated that serum potassium levels increase when ACE inhibitors and ARB therapy is initiated and decrease when the drug is lowered. There are case reports of hyperkalemia during concurrent therapy with ARBs and spironolactone and with aliskiren and spironolactone. Based on this data, serum potassium levels should be monitored in patients receiving concomitant ARBs with potassium sparing diuretics.

Angiotensin II Receptor Blocker (ARB)/Potassium Supplements SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Angiotensin II receptor blockers (ARBs) may decrease the renal excretion of potassium. CLINICAL EFFECTS: Concurrent use of potassium supplements with ARBs may result in hyperkalemia. PREDISPOSING FACTORS: Impaired renal function; diabetes mellitus. PATIENT MANAGEMENT: Monitor serum potassium and adjust the dosage accordingly in patients receiving concurrent therapy with potassium supplements and ARBs. DISCUSSION: Several studies have indicated that serum potassium levels increase when ARB therapy is initiated and decrease when the drug is lowered. Based on this data, serum potassium levels should be monitored in patients receiving potassium supplements with ARBs.

ACE Inhibitors; ARBs/Loop Diuretics SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: The exact mechanism is unknown. The initial hypotensive effect of the ACE inhibitors is mainly the result of suppression of the renin-angiotensin-aldosterone system. The ACE inhibitors inhibit the formation of angiotensin II and angiotensin II receptor antagonists block the action of angiotensin II, thereby lowering aldosterone levels with subsequent sodium and water depletion. Agents such as the loop diuretics that cause sodium and water loss may exaggerate the hypotensive state. CLINICAL EFFECTS: The addition of an ACE inhibitor to a patient receiving a loop diuretic may result in severe postural hypotension. This effect is transient and is not expected to occur during long-term dosing. Symptomatic hypotension may result in patients treated with loop diuretics who are started on an angiotensin II receptor antagonist. Concurrent use of a renin-angiotensin system (RAS) inhibitor with diuretics and NSAIDs may result in increased risk of acute kidney injury (AKI). PREDISPOSING FACTORS: Addition of an ACE inhibitor or an angiotensin II receptor antagonist to a patient already receiving a diuretic or who is sodium depleted. Low water intake/dehydration, drug sensitivity, greater than 75 years of age, and renal impairment may increase an individual's susceptibility to AKI. PATIENT MANAGEMENT: In patients without heart failure, it may be advisable to discontinue the diuretic, reduce the dose of the diuretic, or increase salt intake prior to the initiation of the ACE inhibitor. If hypotension occurs, place the patient in a supine position. Hypotension is most likely when the ACE inhibitor is initiated. However, if subsequent hypotension occurs, a dosage adjustment or discontinuation of one agent may be required. Intravascular volume depletion should be corrected in patients prior to the initiation of an angiotensin II receptor antagonist. Concurrent use of a RAS inhibitor with loop diuretics and NSAIDs 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, 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.(4,5) 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). (6) Severe postural hypotension(1,2) and transient postural hypotension(3) has been reported in patients receiving concurrent captopril and furosemide. The effect is transient and may be more prevalent in patients who are sodium depleted.(8) Reversible renal failure(9) and decreased renal function(10) have been reported in patients receiving concurrent administration with enalapril and furosemide. In a study in which electrolytes were replaced with saline or Ringer's solution, no postural hypotension was noted; however, significant decreases in diastolic blood pressure occurred at three, four, and six hours after concurrent administration.(11)	BUMETANIDE, EDECRIN, ENBUMYST, ETHACRYNATE SODIUM, ETHACRYNIC ACID, FUROSCIX, FUROSEMIDE, FUROSEMIDE-0.9% NACL, LASIX, LASIX ONYU, SOAANZ, TORSEMIDE
Drospirenone/ACE Inhibitors; ARBs SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Drospirenone has antimineralocorticoid activity and may cause hyperkalemia. ACE inhibitors and angiotensin II receptor antagonists may also increase potassium levels.(1) CLINICAL EFFECTS: Concurrent use of drospirenone and ACE inhibitors or angiotensin II receptor antagonists may result in hyperkalemia.(1) PREDISPOSING FACTORS: Renal insufficiency, hepatic dysfunction, adrenal insufficiency, and use of potassium supplements, potassium-sparing diuretics, heparin, and NSAIDs may increase potassium levels.(1) PATIENT MANAGEMENT: Patients receiving drospirenone with either an ACE inhibitor or an angiotensin II receptor antagonist should have their serum potassium level checked during the first treatment cycle.(1) DISCUSSION: Drospirenone has antimineralocorticoid activity comparable to 25 mg of spironolactone and may result in hyperkalemia. Concurrent use of ACE inhibitors or angiotensin II receptor antagonists may also increase potassium levels.(1) In a study in 24 mildly hypertensive postmenopausal women who received concurrent drospirenone/estradiol (3 mg/1 mg) with enalapril (10 mg), mean serum potassium levels were 0.22 mEq/L higher than in the placebo group. On day 14 of concurrent therapy, the ratios for serum potassium maximum concentration (Cmax) and area-under-curve (AUC) were 0.955 and 1.010, respectively. No patient developed hyperkalemia.(1)	ANGELIQ, BEYAZ, DROSPIRENONE-ETH ESTRA-LEVOMEF, DROSPIRENONE-ETHINYL ESTRADIOL, JASMIEL, LO-ZUMANDIMINE, LORYNA, NEXTSTELLIS, NIKKI, OCELLA, SAFYRAL, SLYND, SYEDA, TYDEMY, VESTURA, YASMIN 28, YAZ, ZARAH, ZUMANDIMINE
Selected MAOIs/Selected Antihypertensive Agents SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Both MAOIs and antihypertensive agents may increase the risk of postural hypotension.(1,2) CLINICAL EFFECTS: Postural hypotension may occur with concurrent therapy of MAOIs and antihypertensive agents.(1,2) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: The manufacturer of phenelzine states all patients should be followed closely for symptoms of postural hypotension. Hypotensive side effects have occurred in patients who have been hypertensive and normotensive, as well as hypotensive at initiation of phenelzine.(1) The manufacturer of tranylcypromine states hypotension has been observed most commonly but not exclusively in patients with pre-existing hypertension. Tranylcypromine doses greater than 30 mg daily have a major side effect of postural hypotension and can lead to syncope. Gradual dose titration is recommended to decrease risk of postural hypotension. Combined use with other agents known to cause hypotension have shown to have additive side effects and should be monitored closely.(2) Monitor the patient for signs and symptoms of postural hypotension including dizziness, lightheadedness, or weakness, especially upon standing. Monitor blood pressure as well as orthostatic vitals and adjust antihypertensive therapy, including decreasing the dose, dividing doses, or scheduling doses at bedtime, as needed to maintain goal blood pressure. If blood pressure remains hypotensive, consider decreasing the dose of phenelzine or tranylcypromine. In some cases, discontinuation of one or both agents may be necessary.(3) Normotensive patients on stable antihypertensive therapy who are started on either phenelzine or tranylcypromine may be at increased risk for hypotension. Hypertensive patients on stable phenelzine or tranylcypromine who require antihypertensive therapy would be at decreased risk for hypotension. DISCUSSION: A review article describes the pharmacology of phenelzine and tranylcypromine as non-selective MAOIs which inhibit both type A and type B substrates. Orthostatic hypotension is described as the most common MAOI side effect and usually occurs between initiation and the first 3-4 weeks of therapy.(3) In a double-blind study, 71 patients were randomized to receive a 4-week trial of either tranylcypromine, amitriptyline, or the combination. The number of patients reporting dizziness at 4 weeks was not different between the three treatment groups (tranylcypromine 52.4%; amitriptyline 65%; combination 66.7%). Blood pressure (BP) assessment noted a significant drop in standing BP in the tranylcypromine group compared to baseline (systolic BP change = -10 mmHg; p<0.02 and diastolic BP change = -9 mmHg; p<0.02). Combination therapy also had a significant drop in standing BP compared to baseline (systolic BP change = -9 mmHg; p<0.02). Patients receiving amitriptyline had no significant change in BP from baseline at 4 weeks. All three groups had a trend toward increasing orthostatic hypotension in BP changes from lying to standing. The change in orthostatic hypotension was significant in the amitriptyline group with an average systolic BP orthostatic drop of -9 mmHg (p<0.05).(4) A randomized, double-blind study of 16 inpatients with major depressive disorder were treated with either phenelzine or tranylcypromine. Cardiovascular assessments were completed at baseline and after 6 weeks of treatment. After 6 weeks, 5/7 patients (71%) who received phenelzine had a decrease in standing systolic BP greater than 20 mmHg from baseline. Head-up tilt systolic and diastolic BP decreased from baseline in patients on phenelzine (98/61 mmHg v. 127/65 mmHg, respectively; systolic change p=0.02 and diastolic change p=0.02). After 6 weeks, 6/9 patients (67%) who received tranylcypromine had a decrease in standing systolic BP greater than 20 mmHg from baseline. Head-up tilt systolic and diastolic BP decreased from baseline in patients on tranylcypromine (113/71 mmHg v. 133/69 mmHg, respectively; systolic change p=0.09 and diastolic change p=0.07).(5) Selected MAOIs linked to this monograph include: phenelzine and tranylcypromine. Selected antihypertensive agents include: ACE inhibitors, alpha blockers, ARBs, beta blockers, calcium channel blockers, aprocitentan, clonidine, hydralazine, moxonidine, and sparsentan.

Tizanidine/Selected Antihypertensives SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Tizanidine is an alpha-2 agonist. Concurrent use with antihypertensive agents may result in additive effects on blood pressure.(1) CLINICAL EFFECTS: Concurrent use of antihypertensives and tizanidine may result in hypotension.(1) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: Patients receiving concurrent therapy should be monitored for hypotension. The risk of hypotension may be decreased by careful titration of tizanidine dosages and monitoring for hypotension prior to dose advancement. Counsel patients about the risk of orthostatic hypotension.(1) DISCUSSION: Severe hypotension has been reported following the addition of tizanidine to existing lisinopril therapy.(2-4)	ONTRALFY, TIZANIDINE HCL, ZANAFLEX
Apomorphine/Selected Antihypertensives and Vasodilators SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Apomorphine causes dose-dependent decreases in blood pressure. Concurrent use with antihypertensive agents may result in additive effects on blood pressure.(1) CLINICAL EFFECTS: Concurrent use of antihypertensives and apomorphine may result in orthostatic hypotension with or without dizziness, nausea, or syncope.(1) PREDISPOSING FACTORS: The risk of orthostatic hypotension may be increased during dose escalation of apomorphine and in patients with renal or hepatic impairment.(1) PATIENT MANAGEMENT: Patients receiving concurrent therapy should be monitored for hypotension. Counsel patients about the risk of orthostatic hypotension.(1) DISCUSSION: Healthy volunteers who took sublingual nitroglycerin (0.4 mg) concomitantly with apomorphine experienced a mean largest decrease in supine systolic blood pressure (SBP) of 9.7 mm Hg and in supine diastolic blood pressure (DBP) of 9.3 mm Hg, and a mean largest decrease in standing SBP and DBP of 14.3 mm Hg and 13.5 mm Hg, respectively. The maximum decrease in SBP and DBP was 65 mm Hg and 43 mm Hg, respectively. When apomorphine was taken alone, the mean largest decrease in supine SBP and DBP was 6.1 mm Hg and 7.3 mm Hg, respectively, and in standing SBP and DBP was 6.7 mm Hg and 8.4 mm Hg, respectively.(1)	APOKYN, APOMORPHINE HCL, ONAPGO
Angiotensin II Receptor Block (ARB)/High-Dose Aspirin 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 aspirin may result in decreased antihypertensive effects of the ARB. In patients with existing renal impairment, the use of these agents may also result in further deterioration of renal clearance caused by renal hypoperfusion. Concurrent use of ARBs with aspirin 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: Monitor patients receiving doses of aspirin higher than 150 mg daily for decreased antihypertensive effects of their ARB. The use of alternative agents may need to be considered. Concurrent use of ARBs with aspirin and diuretics should be used with caution and monitored for signs of AKI. DISCUSSION: 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. In a computational study, the risk of AKI using triple therapy (combination of 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.(4,5) 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).(6)	ACETYL SALICYLIC ACID, ASA-BUTALB-CAFFEINE-CODEINE, ASCOMP WITH CODEINE, ASPIRIN, BUTALBITAL-ASPIRIN-CAFFEINE, CARISOPRODOL-ASPIRIN-CODEINE, NORGESIC, NORGESIC FORTE, ORPHENADRINE-ASPIRIN-CAFFEINE, ORPHENGESIC FORTE, YOSPRALA

Azilsartan can cause fetal harm when administered to a pregnant woman. Use of drugs that act on the RAS during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death. Oligohydramnios caused by drugs that act on the RAS can result in reduced fetal renal function leading to anuria and renal failure, fetal lung hypoplasia, skeletal deformations including skull hypoplasia, hypotension, and death.

Discontinue azilsartan as soon as possible when pregnancy is detected. Perform serial ultrasound examinations to assess the intra-amniotic environment. Fetal testing may be appropriate, based on the week of pregnancy.

Patients and physicians should be aware that oligohydramnios may not appear until after the fetus has sustained irreversible injury. Hypertension in pregnancy increases maternal risk for pre-eclampsia, gestational diabetes, premature delivery, and delivery complications (e.g., need for cesarean section, and post-partum hemorrhage). Hypertension increases the fetal risk for intrauterine growth restriction and death.

Pregnant women with hypertension should be carefully monitored and managed accordingly. Closely observe infants with a history of in utero exposure to azilsartan for hypotension, oliguria, and hyperkalemia. Support blood pressure and renal perfusion if oliguria or hypotension occurs. Exchange transfusions or dialysis may be required to reverse hypotension and/or substitute for disordered renal function.

Azilsartan is distributed into milk in rats; it is not known whether azilsartan is distributed into human milk, its effects on the breast-fed infant, or the effects on milk production. Because of the potential for adverse reactions to azilsartan in nursing infants, breast-feeding is not recommended during treatment with azilsartan.

In clinical studies of azilsartan, 26% of patients were 65 years of age and older, and 5% were 75 years of age and older. Abnormally high serum creatinine values were more likely among patients 75 years of age or older. There were no other differences in safety or effectiveness between elderly and younger patients; however, greater sensitivity of some geriatric patients cannot be ruled out.
