Consumer information for this interaction is not currently available.
MONITOR: Coadministration with inhibitors of CYP450 3A4 may increase the plasma concentrations of lurasidone and its active metabolite, both of which are primarily metabolized by the isoenzyme. When a single 10 mg dose of lurasidone was administered with the potent CYP450 3A4 inhibitor ketoconazole (400 mg/day for 5 days), lurasidone peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 6.9- and 9.0-fold, respectively, compared to administration alone. The AUC of lurasidone's active metabolite increased by 6-fold. Another potent CYP450 3A4 inhibitor, posaconazole, has been reported to increase lurasidone AUC by approximately 4.5-fold. A persistent effect of posaconazole on lurasidone exposure was observed up to 2 to 3 weeks following discontinuation of posaconazole. When a single 20 mg dose of lurasidone was administered with the moderate CYP450 3A4 inhibitor diltiazem (extended release formulation 240 mg/day for 5 days), lurasidone Cmax and AUC increased by 2.1- and 2.2-fold, respectively, while the AUC of the active metabolite increased by 2.4-fold. The use of an immediate release formulation of diltiazem could potentially result in a greater magnitude of interaction, although this was not studied. Data are not available for other, less potent CYP450 3A4 inhibitors.
MANAGEMENT: Pharmacologic response to lurasidone should be monitored more closely whenever a CYP450 3A4 inhibitor is added to or withdrawn from therapy, and the lurasidone dosage adjusted as necessary. Patients should be monitored for potentially increased adverse effects such as dizziness, drowsiness, dry mouth, increased appetite, weight gain, extrapyramidal symptoms, tardive dyskinesia, hyperglycemia, dyslipidemia, hyperprolactinemia (galactorrhea, amenorrhea, gynecomastia), orthostatic hypotension, cognitive and motor impairment, seizures, dysphagia, and heat-related illnesses due to disruption of body temperature regulation.
Drug and food interactions
lurasidone food
Applies to: lurasidone
Avoid consuming grapefruit or grapefruit juice during treatment with lurasidone, as it may increase blood levels of the medication. This can increase the risk of side effects such as Parkinson-like symptoms, abnormal muscle movements, seizures, high blood sugar, diabetes, high cholesterol, weight gain, sex hormone irregularities, and heat-related disorders such as heat intolerance or heat stroke. In addition, you may be more likely to experience side effects associated with low blood pressure such as dizziness, lightheadedness, headache, flushing, fainting, and heart palpitations. You should also avoid the use of alcohol while being treated with lurasidone. Alcohol can increase the nervous system and blood-pressure lowering effects of lurasidone. You may experience increased drowsiness, dizziness, difficulty concentrating, and impairment in thinking and judgment. Talk to your doctor or pharmacist if you have any questions or concerns. Lurasidone should be taken with food consisting of at least 350 calories. Avoid driving or operating hazardous machinery until you know how the medication affects you, and use caution when getting up from a sitting or lying position.
mavorixafor food
Applies to: mavorixafor
Consumer information for this interaction is not currently available.
GENERALLY AVOID: Grapefruit products may significantly increase the plasma concentrations and effects of mavorixafor, which is primarily metabolized by the isoenzyme CYP450 3A4. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. A study examining mavorixafor in combination with the strong CYP450 3A4 and P-glycoprotein inhibitor, itraconazole, suggests an increase in mavorixafor's systemic exposure (AUC) of approximately 2-fold. Clinical data with grapefruit products are not available. Pharmacokinetic interactions involving grapefruit are subject to a high degree of interpatient variability and can also be affected by the product and amount consumed; therefore, the extent to which a given patient may be affected is difficult to predict. Additionally, since mavorixafor is associated with concentration-dependent prolongation of the QT interval, increased levels may potentiate the risk of ventricular arrhythmias such as torsade de pointes and sudden death.
ADJUST DOSING INTERVAL: Food may significantly reduce the peak plasma concentration (Cmax) and systemic exposure (AUC) of mavorixafor. When a single-dose of mavorixafor (400 mg) was administered with a high-fat meal (1000 calories, 50% fat) to healthy subjects, the Cmax and AUC decreased by 66% and 55%, respectively. Similarly, when the same dose was given with a low-fat meal (500 calories, 25% fat) to healthy subjects, mavorixafor's Cmax and AUC decreased by 55% and 51%, respectively. Additionally, a single dose of mavorixafor (400 mg) administered with a low-fat meal to healthy subjects following an overnight fast resulted in a 14% higher Cmax and an 18% lower AUC than those obtained from subjects who fasted for an additional 4 hours after the dose.
MANAGEMENT: Mavorixafor should be taken on an empty stomach after an overnight fast, 30 minutes before food. Patients should be advised to avoid eating or drinking products containing grapefruit, as this could increase the risk of experiencing adverse effects from mavorixafor such as QT prolongation.
