Interactions between your drugs

Minor

nilotinib darolutamide

Applies to: nilotinib and Nubeqa (darolutamide)

Coadministration with inhibitors of CYP450 3A4 and/or P-glycoprotein (P-gp) may increase the plasma concentrations of darolutamide, which is a substrate of both the isoenzyme and the efflux transporter. When darolutamide was coadministered with itraconazole, a dual P-gp and potent CYP450 3A4 inhibitor, mean darolutamide peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 40% and 70%, respectively, compared to administration of darolutamide alone. The interaction has not been studied with less potent inhibitors or lone inhibitors of CYP450 3A4 or P-gp. Caution is advised when darolutamide is used with CYP450 3A4 or P-gp inhibitors. Patients should be monitored more frequently for adverse effects such as fatigue, hypertension, neutropenia and abnormal liver function tests, and the darolutamide dosage adjusted as necessary in accordance with the product labeling.

Drug and food interactions

Major

nilotinib food

Applies to: nilotinib

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of nilotinib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits. Because nilotinib 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 increases the oral bioavailability of nilotinib. The mechanism of interaction is unknown. Compared to the fast state, nilotinib systemic exposure (AUC) increased by 82% when the dose was given 30 minutes after a high-fat meal. Because nilotinib 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.

MANAGEMENT: Patients treated with nilotinib should avoid consumption of grapefruit, grapefruit juice, and any supplement containing grapefruit extract. In addition, no food should be consumed for at least 2 hours before and 1 hour after a nilotinib dose.

Moderate

darolutamide food

Applies to: Nubeqa (darolutamide)

ADJUST DOSING INTERVAL: Food enhances the oral absorption of darolutamide. According to the prescribing information, bioavailability of darolutamide increased by 2.0 to 2.5-fold when administered with food. A similar increase in exposure was observed for the active metabolite keto-darolutamide.

MANAGEMENT: Darolutamide should be administered with food.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
