The following dosing information is available for LATUDA (lurasidone hcl):
Dosage of lurasidone hydrochloride is expressed in terms of the hydrochloride salt.
In patients receiving lurasidone and in whom a moderate inhibitor of cytochrome P-450 (CYP) isoenzyme 3A4 (e.g., atazanavir, diltiazem, erythromycin, fluconazole, verapamil) will be added to therapy, the lurasidone dosage should be reduced to 50% of the original dosage. Similarly, in patients receiving a moderate CYP3A4 inhibitor in whom lurasidone hydrochloride is initiated, the recommended initial dosage of lurasidone hydrochloride is 20 mg daily and the maximum recommended dosage is 80 mg daily. If lurasidone is used concurrently with a moderate CYP3A4 inducer (e.g., bosentan, efavirenz, etravirine, modafinil, nafcillin), it may be necessary to increase the lurasidone dosage after chronic therapy (i.e., >=7 days) with the CYP3A4 inducer.
Lurasidone should not be given concurrently with strong CYP3A4 inhibitors (e.g., clarithromycin, ketoconazole, ritonavir, voriconazole) or strong CYP3A4 inducers (e.g., carbamazepine, phenytoin, rifampin, St. John's wort (Hypericum perforatum)).
In patients receiving lurasidone and in whom a moderate inhibitor of cytochrome P-450 (CYP) isoenzyme 3A4 (e.g., atazanavir, diltiazem, erythromycin, fluconazole, verapamil) will be added to therapy, the lurasidone dosage should be reduced to 50% of the original dosage. Similarly, in patients receiving a moderate CYP3A4 inhibitor in whom lurasidone hydrochloride is initiated, the recommended initial dosage of lurasidone hydrochloride is 20 mg daily and the maximum recommended dosage is 80 mg daily. If lurasidone is used concurrently with a moderate CYP3A4 inducer (e.g., bosentan, efavirenz, etravirine, modafinil, nafcillin), it may be necessary to increase the lurasidone dosage after chronic therapy (i.e., >=7 days) with the CYP3A4 inducer.
Lurasidone should not be given concurrently with strong CYP3A4 inhibitors (e.g., clarithromycin, ketoconazole, ritonavir, voriconazole) or strong CYP3A4 inducers (e.g., carbamazepine, phenytoin, rifampin, St. John's wort (Hypericum perforatum)).
Lurasidone hydrochloride is commercially available as tablets, which are administered orally once daily, usually in the morning or evening, and should be taken with food (containing at least 350 calories) to increase absorption. Food increases peak concentrations and AUC of lurasidone threefold and twofold, respectively; however, lurasidone exposure was not affected as meal size was increased from 350 to 1000 calories and was independent of meal fat content. Lurasidone was administered with food in the controlled clinical studies. Store lurasidone tablets at 25degreesC; excursions permitted to 15-30degreesC.

There are 6 severe interactions.
These drug interactions can produce serious consequences in most patients. Actions required for severe interactions include, but are not limited to, discontinuing one or both agents, adjusting dosage, altering administration scheduling, and providing additional patient monitoring. Review the full interaction monograph for more information.
| Drug Interaction | Drug Names |
|---|---|
| Cabergoline/Selected Dopamine Blockers SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Dopamine (D2) blockers such as the phenothiazines, butyrophenones, thioxanthenes and atypical antipsychotics may decrease the effects of cabergoline, a dopamine agonist.(1) CLINICAL EFFECTS: Concurrent administration of cabergoline with dopamine blockers (e.g. phenothiazines, butyrophenones, or thio xanthines) may decrease the effectiveness of cabergoline.(1) Cabergoline may decrease the effectiveness of antipsychotic treatment. PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: The manufacturer of cabergoline states cabergoline(1) should not be administered concurrently with dopamine antagonists. Avoid concurrent use when possible. If cabergoline is started in a patient receiving long term antipsychotic treatment, monitor closely for loss of antipsychotic efficacy. If an antipsychotic is required for a patient on long term cabergoline therapy, consider use of a shorter half-life, less potent dopamine (D2) blocking atypical antipsychotic (e.g. clozapine, quetiapine) and monitor closely. DISCUSSION: The manufacturer of cabergoline state that it should not be administered concurrently with dopamine antagonists. |
CABERGOLINE |
| Metoclopramide/Antipsychotics; Phenothiazines; Rivastigmine SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: These agents block dopamine (D2) receptors. D2 blockade can cause extrapyramidal reactions, such acute dystonic reactions, pseudoparkinsonian tremors, akathisia, or tardive dyskinesia. Neuroleptic malignant syndrome may also occur in patients receiving D2 blockers. The risk of these adverse effects may be increased by concurrent use.(1-3) CLINICAL EFFECTS: Concurrent use may increase the risk of extrapyramidal reactions (e.g. acute dystonic reactions, pseudoparkinsonian tremors, akathisia, or tardive dyskinesia) and neuroleptic malignant syndrome. Tardive dyskinesia, which may be permanent, typically affects the facial muscles and may result in uncontrollable lip smacking, chewing, puckering of the mouth, frowning or scowling, sticking out the tongue, blinking and moving the eyes, and shaking of the arms and/or legs.(1-3) Symptoms of neuroleptic malignant syndrome include hyperpyrexia, muscle rigidity, altered mental status, an autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac arrhythmias), elevated creatine phosphokinase, myoglobinuria (rhabdomyolysis), and acute renal failure.(1) PREDISPOSING FACTORS: Patients with Parkinson's or Lewy Body Disease may be more likely to have extrapyramidal reactions or unmasking of their primary disease symptoms. The risk of extrapyramidal symptoms is also increased in patients on metoclopramide for longer than 12 weeks. Elderly patients, especially elderly women, and diabetics are at higher risk of developing tardive dyskinesia. Other extrapyramidal symptoms, like acute dystonia, have occurred more frequently in patients younger than 30 years old.(1) PATIENT MANAGEMENT: The concurrent use of metoclopramide and agents likely to cause extrapyramidal reactions should be avoided.(1) If concurrent use is warranted, monitor patients closely for extrapyramidal reactions and neuroleptic malignant syndrome. The manufacturer of metoclopramide says to avoid treatment with metoclopramide for longer than 12 weeks, and to use the lowest possible dose.(1) Discontinue therapy if symptoms occur. Instruct patients to seek immediate medical attention if symptoms develop. Symptoms of extrapyramidal reactions, including tardive dyskinesia, include involuntary movements of limbs and facial grimacing, torticollis, oculogyric crisis, rhythmic protrusion of the tongue, bulbar type of speech, trismus, and/or dystonic reactions resembling tetanus/stridor/dyspnea.(3) DISCUSSION: Both metoclopramide and phenothiazines can cause extrapyramidal reactions, such as tardive dyskinesia, and neuroleptic malignant syndrome. The risk may be increased by concurrent use.(1,2) Extrapyramidal symptoms have been reported with concurrent metoclopramide and neuroleptics, prochlorperazine, and chlorpromazine.(4-6) |

| Lomitapide (Less Than or Equal To 30 mg)/Weak CYP3A4 Inhibitors SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Weak inhibitors of CYP3A4 may inhibit the metabolism of lomitapide.(1) Lomitapide is very susceptible to CYP3A4 inhibition. For example, in an interaction study with a strong CYP3A4 inhibitor (ketoconazole) lomitapide exposure was increased 27-fold.(2) Thus even weak CYP3A4 inhibitors may affect lomitapide exposure (AUC, area-under-curve). CLINICAL EFFECTS: Concurrent use of a weak inhibitor of CYP3A4 may result in 2-fold increases in lomitapide levels and toxicity from lomitapide.(1) PREDISPOSING FACTORS: This interaction may be more severe in patients with hepatic impairment or with end-stage renal disease.(1) PATIENT MANAGEMENT: The maximum lomitapide dose should be 30 mg daily for patients taking concomitant weak CYP3A4 inhibitors. Due to lomitapide's long half-life, it may take 1 to 2 weeks to see the full effect of this interaction. When initiating a weak CYP3A4 inhibitor in patients taking lomitapide 10 mg daily or more, decrease the dose of lomitapide by 50%. In patients taking lomitapide 5 mg daily, continue current dose. DISCUSSION: Lomitapide is very susceptible to CYP3A4 inhibition. For example, in an interaction study with a strong CYP3A4 inhibitor (ketoconazole) lomitapide exposure was increased 27-fold.(2) Based upon interactions with stronger inhibitors, weak inhibitors of CYP3A4 are predicted to increase lomitapide area-under-curve(AUC) 2-fold.(1) Weak CYP3A4 inhibitors linked to this interaction include alprazolam, amiodarone, amlodipine, asciminib, atorvastatin, azithromycin, Baikal skullcap, belumosudil, bicalutamide, blueberry juice, brodalumab, cannabidiol, capivasertib, cilostazol, cimetidine, ciprofloxacin, chlorzoxazone, clotrimazole, cranberry juice, cyclosporine, daridorexant, delavirdine, diosmin, everolimus, flibanserin, fosaprepitant, fostamatinib, gepotidacin, ginkgo, givinostat, glecaprevir/pibrentasvir, goldenseal, grazoprevir, isoniazid, istradefylline, ivacaftor, larotrectinib, lacidipine, lapatinib, lazertinib, leflunomide, levamlodipine, linagliptin, lurasidone, maribavir, mavorixafor, olaparib, osilodrostat, palbociclib, pazopanib, peppermint oil, piperine, propiverine, propofol, ranitidine, ranolazine, remdesivir, resveratrol, roxithromycin, rucaparib, selpercatinib, sitaxsentan, skullcap, teriflunomide, ticagrelor, tolvaptan, trofinetide, viloxazine, vonoprazan, and zileuton.(1-3) |

| Opioids (Cough and Cold)/Antipsychotics; Phenothiazines SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Concurrent use of opioids and antipsychotics, including phenothiazine derivatives, may result in additive CNS depression.(1) CLINICAL EFFECTS: Concurrent use of opioids and other CNS depressants, such as antipsychotics, including phenothiazine derivatives, may result in profound sedation, respiratory depression, coma, and/or death.(1) PREDISPOSING FACTORS: Concurrent use of alcohol or other CNS depressants may increase the risk of adverse effects. PATIENT MANAGEMENT: Avoid prescribing opioid-including cough medications for patients taking CNS depressants such as antipsychotics, including phenothiazine derivatives.(1) Respiratory depression can occur at any time during opioid therapy, especially during therapy initiation and following dosage increases. Consider this risk when using concurrently with other agents that may cause CNS depression.(2) If concurrent use is necessary, monitor patients for unusual dizziness or lightheadedness, extreme sleepiness, slowed or difficult breathing, or unresponsiveness.(1) Discuss naloxone with all patients when prescribing or renewing an opioid analgesic or medicine to treat opioid use disorder (OUD). Consider prescribing naloxone to patients prescribed medicines to treat OUD or opioid analgesics (such as those taking CNS depressants) who are at increased risk of opioid overdose and when a patient has household members/close contacts at risk for accidental overdose.(3) DISCUSSION: A nested case-control study looked at the relationship between antipsychotic use and risk of acute respiratory failure. Current use of antipsychotics was associated with a 2.33-fold increase in risk of respiratory failure compared to no use of antipsychotics. The risk was also significantly increased in patients with recent use of antipsychotics (within the past 15-30 days, OR = 1.79) and recent past use (within 31-90 days OR = 1.41). The risk increased with higher doses and longer duration of use.(4) Between 2002 and 2014, the number of patients receiving an opioid analgesic increased 8%, from 75 million to 81 million patients, and the number of patients receiving a benzodiazepine increased 31%, from 23 million to 30 million patients. During this time, the proportion of patients receiving concurrent therapy increased 31%, from 23 million to 30 million patients.(5) From 2004 to 2011, the rate of nonmedical use-related emergency room visits involving both opioids and benzodiazepines increased from 11 to 34.2 per 100,000 and drug overdose deaths involving both opioids and benzodiazepines increased from 0.6 to 1.7 per 100,000. The proportion of prescription opioid analgesic deaths which also involved benzodiazepines increased from 18% to 31% during this time.(6) A prospective observational cohort study in North Carolina found that the rates of overdose death among patients co-dispensed opioid analgesics and benzodiazepines were 10 times higher than patients receiving opioid analgesics alone.(7) A case-cohort study of VA data from 2004-2009 found that the risk of death from overdose increased with concomitant opioid analgesics and benzodiazepines. Compared to patients with no history of benzodiazepines, patients with a history of benzodiazepine use (hazard ratio [HR] = 2.33) and patients with a current benzodiazepine prescription (HR=3.86) had an increased risk of fatal overdose.(8) A study found that opioid analgesics contributed to 77% of deaths in which benzodiazepines were determined to be a cause of death and that benzodiazepines contributed to 30% of deaths in which opioid analgesics were determined to be a cause of death. This study also found that other CNS depressants (including barbiturates, antipsychotic and neuroleptic drugs, antiepileptic and antiparkinsonian drugs, anesthetics, autonomic nervous system drugs, and muscle relaxants) were contributory to death in many cases where opioid analgesics were also implicated.(9) A study found that alcohol was involved in 18.5% of opioid analgesic abuse-related ED visits and 22.1 percent of opioid analgesic-related deaths.(10) |

| Eliglustat/Weak CYP3A4 Inhibitors SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Weak inhibitors of CYP3A4 may inhibit the metabolism of eliglustat. If the patient is also taking an inhibitor of CYP2D6, eliglustat metabolism can be further inhibited.(1) CLINICAL EFFECTS: Concurrent use of an agent that is a weak inhibitor of CYP3A4 may result in elevated levels of and clinical effects of eliglustat, including prolongation of the PR, QTc, and/or QRS intervals, which may result in life-threatening cardiac arrhythmias.(1) PREDISPOSING FACTORS: If the patient is also taking an inhibitor of CYP2D6, is a poor metabolizer of CYP2D6, and/or has hepatic impairment, eliglustat metabolism can be further inhibited.(1) The risk of QT prolongation or torsades de pointes may be increased in patients with cardiovascular disease (e.g. heart failure, myocardial infarction, history of torsades de pointes, congenital long QT syndrome), hypokalemia, hypomagnesemia, hypocalcemia, bradycardia, female gender, or advanced age.(2) Concurrent use of more than one drug known to cause QT prolongation or higher systemic concentrations of either QT prolonging drug are additional risk factors for torsades de pointes. Factors which may increase systemic drug concentrations include rapid infusion of an intravenous dose or impaired metabolism or elimination of the drug (e.g. coadministration with an agent which inhibits its metabolism or elimination, genetic impairment in drug metabolism or elimination, and/or renal/hepatic dysfunction).(2) PATIENT MANAGEMENT: The concurrent use of eliglustat with weak inhibitors of CYP3A4 in poor metabolizers of CYP2D6 should be avoided.(1) The dosage of eliglustat with weak inhibitors of CYP3A4 in extensive metabolizers of CYP2D6 with mild (Child-Pugh Class A) hepatic impairment should be limited to 84 mg daily.(1) If concurrent therapy is warranted, consider obtaining serum calcium, magnesium, and potassium levels and monitoring ECG at baseline and at regular intervals. Correct any electrolyte abnormalities. Instruct patients to report any irregular heartbeat, dizziness, or fainting. DISCUSSION: Ketoconazole (400 mg daily), a strong inhibitor of CYP3A4, increased eliglustat (84 mg BID) maximum concentration (Cmax) and area-under-curve (AUC) by 4-fold and 4.4-fold, respectively, in extensive metabolizers. Physiologically-based pharmacokinetic (PKPB) models suggested ketoconazole would increase eliglustat Cmax and AUC by 4.4-fold and 5.4-fold, respectively, in intermediate metabolizers. PKPB models suggested ketoconazole may increase the Cmax and AUC of eliglustat (84 mg daily) by 4.3-fold and 6.2-fold, respectively, in poor metabolizers.(1) PKPB models suggested fluconazole, a moderate inhibitor of CYP3A4, would increase eliglustat Cmax and AUC by 2.8-fold and 3.2-fold, respectively, in extensive metabolizers and by 2.5-fold and 2.9-fold, respectively in intermediate metabolizers. PKPB models suggest that concurrent eliglustat (84 mg BID), paroxetine (a strong inhibitor of CYP2D6), and ketoconazole would increase eliglustat Cmax and AUC by 16.7-fold and 24.2-fold, respectively, in extensive metabolizers. In intermediate metabolizers, eliglustat Cmax and AUC would be expected to increase 7.5-fold and 9.8-fold, respectively.(1) PKPB models suggest that concurrent eliglustat (84 mg BID), terbinafine (a moderate inhibitor of CYP2D6), and ketoconazole would increase eliglustat Cmax and AUC by 10.2-fold and 13.6-fold, respectively, in extensive metabolizers. In intermediate metabolizers, eliglustat Cmax and AUC would be expected to increase 4.2-fold and 5-fold, respectively.(1) Weak inhibitors of CYP3A4 include: alprazolam, amlodipine, asciminib, azithromycin, Baikal skullcap, belumosudil, berberine, bicalutamide, blueberry, brodalumab, cannabidiol, chlorzoxazone, cilostazol, cimetidine, ciprofloxacin, clotrimazole, cranberry, cyclosporine, daclatasvir, daridorexant, delavirdine, dihydroberberine, diosmin, everolimus, flibanserin, fosaprepitant, fostamatinib, gepotidacin, ginkgo, givinostat, glecaprevir/pibrentasvir, goldenseal, grazoprevir, isoniazid, istradefylline, ivacaftor, lacidipine, lapatinib, larotrectinib, lazertinib, leflunomide, levamlodipine, linagliptin, lomitapide, lurasidone, olaparib, osilodrostat, palbociclib, pazopanib, peppermint oil, piperine, propiverine, propofol, ranolazine, remdesivir, resveratrol, roxithromycin, rucaparib, selpercatinib, simeprevir, sitaxsentan, skullcap, suvorexant, teriflunomide, ticagrelor, tolvaptan, trofinetide, and vonoprazan.(3,4) |

| Selected Sensitive CYP3A4 Substrates/Oral Lefamulin SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Lefamulin is considered a moderate inhibitor of CYP3A4. FDA defines a moderate inhibitor as a drug which increases the area-under-curve (AUC) of a sensitive substrate by 2- to 5-fold.(1,4) CLINICAL EFFECTS: Concurrent use of oral lefamulin may lead to increased serum levels and adverse effects of drugs sensitive to inhibition of the CYP3A4 pathway.(1) PREDISPOSING FACTORS: With darifenacin, the risk of anticholinergic toxicities including cognitive decline, delirium, falls and fractures is increased in geriatric patients using more than one medicine with anticholinergic properties.(5) PATIENT MANAGEMENT: If oral lefamulin must be coadministered with a sensitive CYP3A4 substrate, it is recommended to closely monitor for adverse effects of the CYP3A4 substrate.(1) Drug-specific recommendations: The manufacturer of abemaciclib recommends monitoring for adverse reactions and considering a dose reduction of abemaciclib in 50 mg decrements as detailed in prescribing information (based on starting dose, previous dose reductions, and combination or monotherapy use) with concurrent use of moderate CYP3A4 inhibitors.(2) The US manufacturer of sirolimus protein-bound injection (Fyarro) states a dose reduction to 56 mg/m2 is recommended when used concurrently with moderate or weak CYP3A4 inhibitors. Concurrent use with strong CYP3A4 inhibitors should be avoided.(3) DISCUSSION: In a study, oral lefamulin tablets administered concomitantly with and at 2 or 4 hours before oral midazolam (a CYP3A4 substrate) increased the area-under-curve (AUC) and maximum concentration (Cmax) of midazolam by 200% and 100%, respectively. No clinically significant effect on midazolam pharmacokinetics was observed when co-administered with lefamulin injection.(1) Sensitive CYP3A4 substrates linked to this monograph include: abemaciclib, acalabrutinib, alfentanil, alprazolam, atorvastatin, brotizolam, budesonide, buspirone, cobimetinib, darifenacin, ebastine, eletriptan, elvitegravir, everolimus, lovastatin, lurasidone, maraviroc, midazolam, nisoldipine, paritaprevir, sildenafil, simvastatin, sirolimus, ticagrelor, triazolam, and ulipristal.(1,4,6) |

| Lurasidone (Less Than or Equal To 80 mg)/Fluconazole SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Moderate CYP3A4 inhibitors such as fluconazole may inhibit the metabolism of lurasidone.(1) CLINICAL EFFECTS: Concomitant use of lurasidone with inhibitors of CYP3A4 may lead to orthostatic hypotension, akathisia, acute dystonia, Parkinsonism or other lurasidone toxicities.(1) PREDISPOSING FACTORS: Elderly patients, particularly those with a history of falls or swallowing disorders, and patients with Parkinson Disease, Lewy Body Disease, or other dementias are more sensitive to antipsychotics and have a greater risk for adverse effects.(1) PATIENT MANAGEMENT: The US manufacturer of lurasidone states that the dose of lurasidone should not exceed 80 mg daily if coadministered with moderate CYP3A4 inhibitors, such as fluconazole.(1) If a patient is currently on lurasidone and a moderate CYP3A4 inhibitor, such as fluconazole, is added to therapy, the dose of lurasidone should be decreased by 50% of the original dose.(1) If a patient is currently on a moderate CYP3A4 inhibitor, such as fluconazole, and lurasidone is added to therapy, the recommended starting dose of lurasidone is 20 mg per day.(1) DISCUSSION: Pretreatment with diltiazem (240 mg daily for 5 days), another moderate inhibitor of CYP3A4, increased the maximum concentration (Cmax) and area-under-curve (AUC) of a single dose of lurasidone (20 mg) by 2.1-fold, and 2.2-fold, respectively.(1) |
DIFLUCAN, FLUCONAZOLE, FLUCONAZOLE-NACL |
| Selected Dopamine Agonists/Select Atypical Antipsychotics SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Selected dopamine agonists are used to treat neurologic conditions such as Parkinson Disease (PD) or restless legs syndrome, and endocrine disorders such as hyperprolactinemia by directly or indirectly increasing dopamine concentrations at D2 receptors in the central nervous system (CNS). Antipsychotic agents counteract this effect by blocking dopamine activity at CNS D2 receptors.(1-5) CLINICAL EFFECTS: The efficacy of either agent may be decreased, leading to exacerbation of the disease being treated, e.g. Parkinson disease or a psychotic disorder. Dopamine agonists linked to this monograph are: bromocriptine, entacapone, levodopa, pergolide, pramipexole, ropinirole and rotigotine. Atypical antipsychotics linked to this monograph are: aripiprazole, asenapine, iloperidone, lumateperone, lurasidone, paliperidone, quetiapine, risperidone, ziprasidone and zotepine. PREDISPOSING FACTORS: Patients with Parkinson or Diffuse Lewy Body (DLB) disease are particularly susceptible to adverse effects of dopamine blockade by antipsychotics. PATIENT MANAGEMENT: Reassess the need for antipsychotic therapy. If psychosis or hallucinations are due to an antiparkinson agent, when possible consider reducing the dose or changing the antiparkinson agent before initiating antipsychotic therapy. In patients with PD and dementia, addition of a cholinesterase inhibitor (e.g. rivastigmine) may improve psychosis. If an antipsychotic is required, then an atypical antipsychotic should be used.(6,7) In patients with major psychotic disorders, consider reducing the dose, changing, or stopping the dopamine agonist. The US manufacturer of ropinirole recommends treatment with dopamine agonists only if potential benefits outweigh risks.(1) The US manufacturer of entacapone states it should not ordinarily be used in patients with major psychotic disorders as entacapone may lead to an exacerbation of psychosis.(4) DISCUSSION: An epidemiologic study evaluated 21,043 elderly patients with Parkinson disease to determine if recent initiation of a typical or atypical antipsychotic was associated with increased mortality. They found an adjusted odds ratio of 2.0 for death associated with atypical antipsychotics versus no antipsychotic. They found an adjusted odds ratio of 2.4 for death associated with typical versus atypical antipsychotics. The authors noted the increased mortality found with typical antipsychotics supports current treatment recommendations to use atypical antipsychotic agents in patients with Parkinson disease.(6,7) Two clozapine trials showed significant improvement in psychosis without worsening of motor symptoms. In contrast, two olanzapine trials were associated with unacceptable worsening of motor symptoms. Risperidone has also been associated with motor worsening in case reports. Quetiapine evaluations have been conflicting with several small studies showing improvement in psychotic symptoms while a more rigorous trial showed no improvement.(6) |

| Opioids (Extended Release)/Antipsychotics; Phenothiazines SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Concurrent use of opioids and antipsychotics, including phenothiazine derivatives, may result in additive CNS depression.(1) CLINICAL EFFECTS: Concurrent use of opioids and other CNS depressants, such as antipsychotics, including phenothiazine derivatives, may result in profound sedation, respiratory depression, coma, and/or death.(1) PREDISPOSING FACTORS: Concurrent use of alcohol or other CNS depressants may increase the risk of adverse effects. PATIENT MANAGEMENT: Limit prescribing opioid analgesics with CNS depressants such as antipsychotics, including phenothiazine derivatives, to patients for whom alternatives are inadequate.(1) If concurrent use is necessary, limit the dosages and duration of each drug to the minimum possible while achieving the desired clinical effect. If starting a CNS depressant (for an indication other than epilepsy) with an opioid analgesic, prescribe a lower initial dose of the CNS depressant than indicated in the absence of an opioid and titrate based upon clinical response. If an opioid analgesic is indicated in a patient already taking a CNS depressant, prescribe a lower dose of the opioid and titrate based upon clinical response.(1) Respiratory depression can occur at any time during opioid therapy, especially during therapy initiation and following dosage increases. Consider this risk when using concurrently with other agents that may cause CNS depression.(2) Monitor patients receiving concurrent therapy for unusual dizziness or lightheadedness, extreme sleepiness, slowed or difficult breathing, or unresponsiveness.(1) Discuss naloxone with all patients when prescribing or renewing an opioid analgesic or medicine to treat opioid use disorder (OUD). Consider prescribing naloxone to patients prescribed medicines to treat OUD or opioid analgesics (such as those taking CNS depressants) who are at increased risk of opioid overdose and when a patient has household members/close contacts at risk for accidental overdose.(3) DISCUSSION: A nested case-control study looked at the relationship between antipsychotic use and risk of acute respiratory failure. Current use of antipsychotics was associated with a 2.33-fold increase in risk of respiratory failure compared to no use of antipsychotics. The risk was also significantly increased in patients with recent use of antipsychotics (within the past 15-30 days, OR = 1.79) and recent past use (within 31-90 days OR = 1.41). The risk increased with higher doses and longer duration of use.(4) Between 2002 and 2014, the number of patients receiving an opioid analgesic increased 8%, from 75 million to 81 million patients, and the number of patients receiving a benzodiazepine increased 31%, from 23 million to 30 million patients. During this time, the proportion of patients receiving concurrent therapy increased 31%, from 23 million to 30 million patients.(5) From 2004 to 2011, the rate of nonmedical use-related emergency room visits involving both opioids and benzodiazepines increased from 11 to 34.2 per 100,000 and drug overdose deaths involving both opioids and benzodiazepines increased from 0.6 to 1.7 per 100,000. The proportion of prescription opioid analgesic deaths which also involved benzodiazepines increased from 18% to 31% during this time.(6) A prospective observational cohort study in North Carolina found that the rates of overdose death among patients co-dispensed opioid analgesics and benzodiazepines were 10 times higher than patients receiving opioid analgesics alone.(7) A case-cohort study of VA data from 2004-2009 found that the risk of death from overdose increased with concomitant opioid analgesics and benzodiazepines. Compared to patients with no history of benzodiazepines, patients with a history of benzodiazepine use (hazard ratio [HR] = 2.33) and patients with a current benzodiazepine prescription (HR=3.86) had an increased risk of fatal overdose.(8) A study found that opioid analgesics contributed to 77% of deaths in which benzodiazepines were determined to be a cause of death and that benzodiazepines contributed to 30% of deaths in which opioid analgesics were determined to be a cause of death. This study also found that other CNS depressants (including barbiturates, antipsychotic and neuroleptic drugs, antiepileptic and antiparkinsonian drugs, anesthetics, autonomic nervous system drugs, and muscle relaxants) were contributory to death in many cases where opioid analgesics were also implicated.(9) A study found that alcohol was involved in 18.5% of opioid analgesic abuse-related ED visits and 22.1 percent of opioid analgesic-related deaths.(10) |

| Slt Opioids (Immediate Release)/Antipsychotics;Phenothiazine SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Concurrent use of opioids and antipsychotics, including phenothiazine derivatives, may result in additive CNS depression.(1) CLINICAL EFFECTS: Concurrent use of opioids and other CNS depressants, such as antipsychotics, including phenothiazine derivatives, may result in profound sedation, respiratory depression, coma, and/or death.(1) PREDISPOSING FACTORS: Concurrent use of alcohol or other CNS depressants may increase the risk of adverse effects. PATIENT MANAGEMENT: Limit prescribing opioid analgesics with CNS depressants such as antipsychotics, including phenothiazine derivatives, to patients for whom alternatives are inadequate.(1) If concurrent use is necessary, limit the dosages and duration of each drug to the minimum possible while achieving the desired clinical effect. If starting a CNS depressant (for an indication other than epilepsy) with an opioid analgesic, prescribe a lower initial dose of the CNS depressant than indicated in the absence of an opioid and titrate based upon clinical response. If an opioid analgesic is indicated in a patient already taking a CNS depressant, prescribe a lower dose of the opioid and titrate based upon clinical response.(1) Respiratory depression can occur at any time during opioid therapy, especially during therapy initiation and following dosage increases. Consider this risk when using concurrently with other agents that may cause CNS depression.(2) Monitor patients receiving concurrent therapy for unusual dizziness or lightheadedness, extreme sleepiness, slowed or difficult breathing, or unresponsiveness.(1) Discuss naloxone with all patients when prescribing or renewing an opioid analgesic or medicine to treat opioid use disorder (OUD). Consider prescribing naloxone to patients prescribed medicines to treat OUD or opioid analgesics (such as those taking CNS depressants) who are at increased risk of opioid overdose and when a patient has household members/close contacts at risk for accidental overdose.(3) DISCUSSION: A nested case-control study looked at the relationship between antipsychotic use and risk of acute respiratory failure. Current use of antipsychotics was associated with a 2.33-fold increase in risk of respiratory failure compared to no use of antipsychotics. The risk was also significantly increased in patients with recent use of antipsychotics (within the past 15-30 days, OR = 1.79) and recent past use (within 31-90 days OR = 1.41).

| Tacrolimus/Moderate and Weak CYP3A4 Inhibitors SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Moderate and weak inhibitors of CYP3A4 may inhibit the metabolism of tacrolimus.(1) CLINICAL EFFECTS: Concurrent use of a CYP3A4 inhibitor may result in elevated levels of and toxicity from tacrolimus, including nephrotoxicity, neurotoxicity, and prolongation of the QTc interval and life-threatening cardiac arrhythmias, including torsades de pointes.(1) PREDISPOSING FACTORS: The risk of QT prolongation or torsade de pointes may be increased in patients with cardiovascular disease (e.g. heart failure, myocardial infarction, history of torsade de pointes, congenital long QT syndrome), hypokalemia, hypomagnesemia, hypocalcemia, bradycardia, female gender, or advanced age.(2) Concurrent use of more than one drug known to cause QT prolongation or higher systemic concentrations of either QT prolonging drug are additional risk factors for torsade de pointes. Factors which may increase systemic drug concentrations include rapid infusion of an intravenous dose or impaired metabolism or elimination of the drug (e.g. coadministration with an agent which inhibits its metabolism or elimination, and/or renal/hepatic dysfunction).(2) PATIENT MANAGEMENT: The US manufacturer of tacrolimus recommends monitoring tacrolimus whole blood trough concentrations and reducing tacrolimus dose if needed.(1) Consider obtaining serum calcium, magnesium, and potassium levels and monitoring ECG at baseline and at regular intervals. Correct any electrolyte abnormalities. Instruct patients to report any irregular heartbeat, dizziness, or fainting. DISCUSSION: In a study of 26 renal transplant recipients, conjugated estrogens 3.75 mg daily increased the tacrolimus dose-corrected concentration of tacrolimus by 85.6%. Discontinuation of the conjugated estrogens led to a decrease in tacrolimus concentration of 46.6%.(3) A case report describes a 65-year-old kidney transplant recipient who was stable on tacrolimus 9 mg per day with trough levels of 5 to 7.5 ng/mL. Ten days after starting on estradiol gel 0.5 mg per day, her tacrolimus level rose to 18.3 ng/mL and serum creatinine (Scr) rose from 1.1 mg/dL at baseline to 2 mg/dL. Tacrolimus dose was reduced by 60%, and trough levels and Scr normalized after two weeks.(4) A study of 16 healthy volunteers found that elbasvir 50 mg/grazoprevir 200 mg daily increased the area-under-curve (AUC) of tacrolimus by 43%, while the maximum concentration (Cmax) of tacrolimus was decreased by 40%.(5) An analysis of FAERS data from 2004-2017, found a significant assoc ation between transplant rejection and concurrent use of tacrolimus and clotrimazole (reporting odds ration 1.92, 95% CI). A retrospective study of 7 heart transplant patients on concurrent tacrolimus and clotrimazole troche showed a significant correlation between tacrolimus trough concentration and AUC after clotrimazole discontinuation. Tacrolimus clearance and bioavailability after clotrimazole discontinuation was 2.2-fold greater (0.27 vs. 0.59 L/h/kg) and the trough concentration decreased from 6.5 ng/mL at 1 day to 5.3 ng/mL at 2 days after clotrimazole discontinuation.(7) A retrospective study of 26 heart transplant patients found that discontinuation of concurrent clotrimazole with tacrolimus in the CYP3A5 expresser group had a 3.3-fold increase in apparent oral clearance and AUC of tacrolimus (0.27 vs. 0.89 L/h/kg) compared to the CYP3A5 non expresser group with a 2.2-fold mean increase (0.18 vs. 0.39 L/h/kg).(8) A study of 6 adult kidney transplant recipients found that clotrimazole (5-day course) increased the tacrolimus AUC 250% and the blood trough concentrations doubled (27.7 ng/ml versus 27.4 ng/ml). Tacrolimus clearance decreased 60% with coadministration of clotrimazole.(9) A case report describes a 23-year-old kidney transplant recipient who was stable on tacrolimus 5 mg twice daily, mycophenolate mofetil 30 mg daily, prednisone (30 mg daily tapered over time to 5 mg), and clotrimazole troche 10 mg four times daily. Discontinuation of clotrimazole resulted in a decrease in tacrolimus trough levels from 13.7 ng/ml to 5.4 ng/ml over a period of 6 days. Clotrimazole was restarted with tacrolimus 6 mg resulting in an increased tacrolimus level of 19.2 ng/ml.(10) A retrospective study in 95 heart transplant recipients on concurrent clotrimazole and tacrolimus found a median tacrolimus dose increase of 66.7% was required after clotrimazole discontinuation. Tacrolimus trough concentration was found to have decreased 42.5% after clotrimazole discontinuation.(11) A retrospective study in 65 pancreas transplant patients on concurrent tacrolimus, clotrimazole, cyclosporine, and prednisone found that clotrimazole discontinuation at 3 months after transplantation may cause significant tacrolimus trough level reductions.(12) Moderate CYP3A4 inhibitors linked to this monograph include: aprepitant, berotralstat, clofazimine, conivaptan, fluvoxamine, lenacapavir, letermovir, netupitant, nirogacestat, and tofisopam.(6) Weak CYP3A4 inhibitors linked to this monograph include: alprazolam, avacopan, baikal skullcap, berberine, bicalutamide, blueberry, brodalumab, chlorzoxazone, cimetidine, cranberry juice, daclatasvir, daridorexant, delavirdine, diosmin, estrogens, flibanserin, fosaprepitant, fostamatinib, ginkgo biloba, givinostat, glecaprevir/pibrentasvir, goldenseal, grazoprevir, isoniazid, istradefylline, ivacaftor, lacidipine, lazertinib, linagliptin, lomitapide, lumateperone, lurasidone, peppermint oil, piperine, propiverine, ranitidine, remdesivir, resveratrol, rimegepant, simeprevir, sitaxsentan, skullcap, suvorexant, ticagrelor, tolvaptan, trofinetide, viloxazine, and vonoprazan-amoxicillin.(6) |

| Lemborexant (Less Than or Equal To 5 mg)/Weak CYP3A4 Inhibitors SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Inhibitors of CYP3A4 may inhibit the metabolism of lemborexant.(1) CLINICAL EFFECTS: Concurrent use of an inhibitor of CYP3A4 may result in increased levels of and effects from lemborexant, including somnolence, fatigue, CNS depressant effects, daytime impairment, headache, and nightmare or abnormal dreams.(1) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: The maximum recommended dose of lemborexant with concurrent use of a weak CYP3A4 inhibitors should not exceed 5 mg per dose.(1) DISCUSSION: Lemborexant is a CYP3A4 substrate. In a PKPB model, concurrent use of lemborexant with itraconazole increased area-under-curve (AUC) and concentration maximum (Cmax) by 3.75-fold and 1.5-fold, respectively. Concurrent use of lemborexant with fluconazole increased AUC and Cmax by 4.25-fold and 1.75-fold, respectively.(1) Weak inhibitors of CYP3A4 include: alprazolam, amiodarone, amlodipine, asciminib, azithromycin, Baikal skullcap, belumosudil, berberine, bicalutamide, blueberry, brodalumab, cannabidiol, capivasertib, chlorzoxazone, cilostazol, cimetidine, ciprofloxacin, clotrimazole, cranberry, cyclosporine, daclatasvir, daridorexant, delavirdine, dihydroberberine, diosmin, everolimus, flibanserin, fosaprepitant, fostamatinib, gepotidacin, ginkgo, givinostat, glecaprevir/pibrentasvir, goldenseal, grazoprevir, isoniazid, istradefylline, ivacaftor, lacidipine, lapatinib, larotrectinib, lazertinib, leflunomide, levamlodipine, linagliptin, lomitapide, lurasidone, mavorixafor, olaparib, osilodrostat, palbociclib, pazopanib, peppermint oil, piperine, propiverine, propofol, ranitidine, ranolazine, remdesivir, resveratrol, roxithromycin, rucaparib, selpercatinib, simeprevir, sitaxsentan, skullcap, suvorexant, teriflunomide, ticagrelor, tolvaptan, trofinetide, viloxazine, and vonoprazan.(1,2) |

| Ubrogepant/Weak CYP3A4 Inhibitors SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Weak inhibitors of CYP3A4 may inhibit the metabolism of ubrogepant.(1) CLINICAL EFFECTS: Concurrent use of ubrogepant with weak CYP3A4 inhibitors may result in an increase in exposure of ubrogepant.(1) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: The manufacturer recommends a dosage adjustment of ubrogepant when used concomitantly with weak CYP3A4 inhibitors. Initial dose of ubrogepant should not exceed 50 mg when used concomitantly with weak inhibitors of CYP3A4. A second dose may be given within 24 hours but should not exceed 50 mg when used concurrently with weak CYP3A4 inhibitors.(1) DISCUSSION: Coadministration of ubrogepant with verapamil, a moderate CYP3A4 inhibitor, resulted in a 3.5-fold and 2.8-fold increase in area-under-curve (AUC) and concentration maximum (Cmax), respectively. No dedicated drug interaction study was conducted to assess concomitant use with weak CYP3A4 inhibitors. The conservative prediction of the maximal potential increase in ubrogepant exposure with weak CYP3A4 inhibitors is not expected to be more than 2-fold.(1) Weak inhibitors of CYP3A4 include: alprazolam, amiodarone, amlodipine, asciminib, azithromycin, Baikal skullcap, berberine, bicalutamide, blueberry, brodalumab, cannabidiol, capivasertib, chlorzoxazone, cilostazol, cimetidine, ciprofloxacin, clotrimazole, cranberry, cyclosporine, daclatasvir, delavirdine, dihydroberberine, diosmin, elagolix, everolimus, flibanserin, fosaprepitant, fostamatinib, gepotidacin, givinostat, glecaprevir/pibrentasvir, goldenseal, grazoprevir, isoniazid, istradefylline, ivacaftor, lacidipine, lapatinib, larotrectinib, lazertinib, leflunomide, levamlodipine, linagliptin, lomitapide, lurasidone, maribavir, mavorixafor, osilodrostat, palbociclib, pazopanib, peppermint oil, piperine, propiverine, propofol, ranitidine, ranolazine, remdesivir, resveratrol, roxithromycin, simeprevir, sitaxsentan, skullcap, suvorexant, teriflunomide, ticagrelor, tolvaptan, trofinetide, viloxazine, and vonoprazan.(2,3) |

| Apomorphine/Select Atypical Antipsychotics SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Apomorphine is a dopamine agonist. Antipsychotic agents counteract this effect by blocking dopamine activity at CNS D2 receptors.(1) CLINICAL EFFECTS: The efficacy of either agent may be decreased, leading to exacerbation of the disease being treated, e.g. Parkinson disease or a psychotic disorder. PREDISPOSING FACTORS: Patients with Parkinson or Diffuse Lewy Body(DLB) disease are particularly susceptible to adverse effects of dopamine blockade by antipsychotics. PATIENT MANAGEMENT: Reassess the need for antipsychotic therapy. If psychosis or hallucinations are due to an antiparkinson agent, when possible consider reducing the dose or changing the antiparkinson agent before initiating antipsychotic therapy. In patients with PD and dementia, addition of a cholinesterase inhibitor (e.g. rivastigmine) may improve psychosis. If an antipsychotic is required, then an atypical antipsychotic should be used.(2,3) The US manufacturer of apomorphine states patients with major psychotic disorders treated with neuroleptics should be treated with dopamine agonists only if the potential benefits outweigh the risks.(1) DISCUSSION: An epidemiologic study evaluated 21,043 elderly patients with Parkinson disease to determine if recent initiation of a typical or atypical antipsychotic was associated with increased mortality. They found an adjusted odds ratio of 2.0 for death associated with atypical antipsychotics versus no antipsychotic. They found an adjusted odds ratio of 2.4 for death associated with typical versus atypical antipsychotics. The authors noted the increased mortality found with typical antipsychotics supports current treatment recommendations to use atypical antipsychotic agents in patients with Parkinson disease.(2,3) Two clozapine trials showed significant improvement in psychosis without worsening of motor symptoms. In contrast, two olanzapine trials were associated with unacceptable worsening of motor symptoms. Risperidone has also been associated with motor worsening in case reports. Quetiapine evaluations have been conflicting with several small studies showing improvement in psychotic symptoms while a more rigorous trial showed no improvement.(2) |

| Sirolimus Protein-Bound/Slt Moderate and Weak CYP3A4 Inhibit SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Moderate and weak CYP3A4 inhibitors may inhibit the metabolism of sirolimus by CYP3A4.(1) CLINICAL EFFECTS: Concurrent use of moderate or weak CYP3A4 inhibitors may result in elevated levels of and side effects from sirolimus.(1) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: The US manufacturer of sirolimus protein-bound injection (Fyarro) states a dose reduction to 56 mg/m2 is recommended when used concurrently with moderate or weak CYP3A4 inhibitors. Concurrent use with strong CYP3A4 inhibitors should be avoided.(1) DISCUSSION: In an open, randomized, cross-over trial in 18 healthy subjects, concurrent single doses of diltiazem (120 mg) and sirolimus (10 mg) increased sirolimus area-under-curve (AUC) and maximum concentration (Cmax) by 60% and by 43%, respectively. Sirolimus apparent oral clearance and volume of distribution decreased by 38% and 45%, respectively. There were no effects on diltiazem pharmacokinetics or pharmacodynamics.(2) In a study in 26 healthy subjects, concurrent sirolimus (2 mg daily) with verapamil (180 mg twice daily) increased sirolimus AUC and Cmax by 2.2-fold and 2.3-fold, respectively. The AUC and Cmax of the active S-enantiomer of verapamil each increased by 1.5-fold. Verapamil time to Cmax (Tmax) was increased by 1.2 hours.(2) Moderate and weak CYP3A4 inhibitors linked to this monograph include: alprazolam, amlodipine, aprepitant, avacopan, azithromycin, berberine, berotralstat, bicalutamide, blueberry, brodalumab, chlorzoxazone, cilostazol, cimetidine, ciprofloxacin, clofazimine, conivaptan, daclatasvir, daridorexant, delavirdine, diosmin, entrectinib, erythromycin, estrogen, flibanserin, fluvoxamine, fosaprepitant, fosnetupitant, fostamatinib, ginkgo, givinostat, glecaprevir/pibrentasvir, goldenseal, grazoprevir, isoniazid, istradefylline, ivacaftor, lacidipine, lazertinib, lenacapavir, levamlodipine, linagliptin, lomitapide, lumateperone, lurasidone, mavorixafor, netupitant, omeprazole, osilodrostat, peppermint oil, piperine, propiverine, propofol, ranitidine, ranolazine, remdesivir, resveratrol, rimegepant, roxithromycin, scutellarin, simeprevir, sitaxsentan, suvorexant, ticagrelor, tofisopam, tolvaptan, trofinetide and vonoprazan.(3,4) |

| Mavacamten/Weak CYP3A4 Inhibitors SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Weak CYP3A4 inhibitors may decrease the metabolism of mavacamten.(1) CLINICAL EFFECTS: Concurrent use of weak CYP3A4 inhibitors may increase the plasma levels and the incidence and severity of adverse reactions of mavacamten.(1) PREDISPOSING FACTORS: CYP2C19 poor metabolizers may experience an increased incidence or severity of adverse effects.(1) PATIENT MANAGEMENT: The UK manufacturer of mavacamten states no dose adjustment is necessary when starting mavacamten in patients on weak CYP3A4 inhibitors or in intermediate, normal, rapid, or ultra-rapid CYP2C19 metabolizers already on mavacamten and starting a weak CYP3A4 inhibitor. In poor CYP2C19 metabolizers already on mavacamten and starting a weak CYP3A4 inhibitor, reduce mavacamten 5 mg to 2.5 mg or if on 2.5 mg pause treatment for 4 weeks. If CYP2C19 phenotype is unknown, consider a mavacamten starting dose of 2.5 mg daily.(1) DISCUSSION: In a PBPK model, concomitant use of mavacamten (15 mg daily) with cimetidine 400 mg twice daily, a weak CYP3A4 inhibitor, was predicted to increase mavacamten area-under-curve (AUC) by 6% and maximum concentration (Cmax) by 4% in poor CYP2C19 metabolizers and by 3% and 2%, respectively, in both intermediate and normal CYP2C19 metabolizers.(2) Weak CYP3A4 inhibitors include: alprazolam, amiodarone, amlodipine, asciminib, azithromycin, Baikal skullcap, belumosudil, berberine, bicalutamide, blueberry, brodalumab, chlorzoxazone, cilostazol, ciprofloxacin, clotrimazole, cranberry, cyclosporine, delavirdine, dihydroberberine, diosmin, everolimus, flibanserin, fosaprepitant, fostamatinib, gepotidacin, ginkgo, givinostat, glecaprevir/pibrentasvir, goldenseal, istradefylline, ivacaftor, lacidipine, lapatinib, leflunomide, levamlodipine, linagliptin, lomitapide, lurasidone, mavorixafor, pazopanib, peppermint oil, propiverine, propofol, ranitidine, remdesivir, resveratrol, roxithromycin, sitaxsentan, skullcap, suvorexant, teriflunomide, ticagrelor, tolvaptan, trofinetide, and viloxazine.(4,5) |

The following precautions are available for LATUDA (lurasidone hcl):
Safety and effectiveness of lurasidone 40-80 mg daily for the treatment of schizophrenia have been established in adolescent patients 13-17 years of age. Safety and efficacy for this indication was established in a 6-week, placebo-controlled study in 326 adolescent patients. Safety and efficacy of lurasidone for schizophrenia have not been established in pediatric patients <13 years of age.
Safety and efficacy of lurasidone 20-80 mg daily for the treatment of bipolar depression have been established in pediatric patients 10-17 years of age. Safety and efficacy for this indication was established in a 6-week, placebo-controlled study in 347 pediatric patients. Safety and efficacy of lurasidone for bipolar depression have not been established in pediatric patients <10 years of age.
Efficacy of lurasidone for the treatment of irritability associated with autistic disorder have not been established in pediatric patients. Treatment with lurasidone 20 mg daily and 60 mg daily failed to demonstrate efficacy in a 6-week study in pediatric patients 6-17 years of age with irritability associated with autistic disorder diagnosed by Diagnostic and Statistical Manual of Mental Disorders, 4th Ed. (DSM-IV) criteria.
The primary endpoint of an improvement from baseline in the irritability subscale of the Aberrant Behavior Checklist (ABC) was not met at 6 weeks. In long term (104-week), open-label study of pediatric patients 6-17 years of age with schizophrenia, bipolar depression, or autistic disorder, z-scores were derived for height based on standardized growth curves adjusted for age and sex. There was minimal deviation from the growth curve in the study.

A pregnancy registry is available that monitors pregnancy outcomes in women exposed to lurasidone during pregnancy. For more information, contact the National Pregnancy Registry for Atypical Antipsychotics at 1-866-961-2388 or visit https://womensmentalhealth.org/clinical-and-research-programs/pregnancyregi stry/.
Neonates exposed to antipsychotic agents during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery. Symptoms reported to date have included agitation, hypertonia, hypotonia, tardive dyskinetic-like symptoms, tremor, somnolence, respiratory distress, and feeding disorder. Monitor neonates for extrapyramidal and/or withdrawal symptoms and manage appropriately. The symptoms have varied in severity; some neonates recovered within hours to days without specific treatment while others have required prolonged hospitalization.

The symptoms have varied in severity; some neonates recovered within hours to days without specific treatment while others have required prolonged hospitalization.
Lactation studies have not been conducted to assess the presence of lurasidone in human milk. The effects of lurasidone on the breast-fed infant or on milk production are not known. Lurasidone is distributed into milk in rats. The developmental and health benefits of breast-feeding should be weighed along with the mother's clinical need for the drug and any potential adverse effects on the breast-fed infant from lurasidone or from the underlying maternal condition.
Clinical trial experience with lurasidone in patients with schizophrenia who are >=65 years of age is insufficient to determine whether they respond differently than younger adults. In geriatric patients (65-85 years of age) with psychosis, serum lurasidone concentrations were similar to those observed in younger adults. The manufacturer states that it is unknown whether dosage adjustment is necessary in geriatric patients on the basis of age alone.
Geriatric patients with dementia-related psychosis treated with lurasidone are at an increased risk of death compared with those treated with placebo. In addition, an increased incidence of adverse cerebrovascular events (cerebrovascular accidents and transient ischemic attacks), including fatalities, has been observed in geriatric patients with dementia-related psychosis treated with certain atypical antipsychotic agents (aripiprazole, olanzapine, risperidone) in placebo-controlled studies. The manufacturer states that lurasidone is not approved for the treatment of patients with dementia-related psychosis. In pooled data analyses, a reduced risk of suicidality was observed in adults >=65 years of age with antidepressant therapy compared with placebo.

The following prioritized warning is available for LATUDA (lurasidone hcl):
WARNING: There may be a slightly increased risk of serious, possibly fatal side effects (such as stroke, heart failure, fast/irregular heartbeat, pneumonia) when this medication is used by older adults with dementia. This medication is not approved for the treatment of dementia-related behavior problems. Discuss the risks and benefits of this medication, as well as other effective and possibly safer treatments for dementia-related behavior problems, with the doctor.
Lurasidone is used to treat certain mental/mood disorders (such as schizophrenia, depression associated with bipolar disorder). Drugs used to treat depression can help prevent suicidal thoughts/attempts and provide other important benefits. However, studies have shown that a small number of people (especially people younger than 25) who take drugs to treat depression may experience worsening depression, other mental/mood symptoms, or suicidal thoughts/attempts.
It is very important to talk with the doctor about the risks and benefits of drugs used to treat depression (especially for people younger than 25), even if treatment is not for a mental/mood condition. Tell the doctor right away if you notice worsening depression/other psychiatric conditions, unusual behavior changes (including possible suicidal thoughts/attempts), or other mental/mood changes (including new/worsening anxiety, panic attacks, trouble sleeping, irritability, hostile/angry feelings, impulsive actions, severe restlessness, very rapid speech). Be especially watchful for these symptoms when a new drug to treat depression is started or when the dose is changed.
