Interactions between your drugs

Moderate

pitolisant tepotinib

Applies to: pitolisant and tepotinib

MONITOR: Coadministration with CYP450 3A4 inducers and/or P-glycoprotein (P-gp) inducers may decrease the plasma concentrations of tepotinib. The proposed mechanism involves induction of CYP450 3A4, which is one of the primary enzymes responsible for the metabolic clearance of tepotinib, and induction of the efflux transporter P-gp, of which tepotinib is also a substrate. However, the effect of CYP450 3A4 inducers and/or P-gp inducers on tepotinib has not been studied clinically.

MANAGEMENT: The potential for diminished pharmacologic effects of tepotinib should be considered during coadministration with CYP450 3A4 inducers and/or P-gp inducers. Alternative treatments may be required if an interaction is suspected.

Drug and food interactions

Moderate

tepotinib food

Applies to: tepotinib

ADJUST DOSING INTERVAL: Food enhances the oral bioavailability of tepotinib. When tepotinib was administered after a high-fat, high-calorie meal (approximately 800 to 1000 calories; 150 calories from protein, 250 calories from carbohydrate, 500 to 600 calories from fat), tepotinib peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 2-fold and 1.6-fold, respectively, compared to administration under fasted conditions.

MANAGEMENT: Tepotinib should be administered with food at approximately the same time each day.

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.
