Interactions between your drugs

Major

voriconazole capmatinib

Applies to: voriconazole and capmatinib

MONITOR CLOSELY: Coadministration of capmatinib with strong CYP450 3A4 inhibitors may increase the risk and severity of capmatinib adverse effects, such as interstitial lung disease, pneumonitis, and hepatotoxicity. The proposed mechanism is decreased clearance due to inhibition of CYP450 3A4, which is one of the primary enzymes responsible for the metabolic clearance of capmatinib. Coadministration with itraconazole (a strong CYP450 3A4 inhibitor) increased the systemic exposure (AUC) of capmatinib by 42%, but did not affect the peak plasma concentration (Cmax) of capmatinib.

MANAGEMENT: Close monitoring is recommended whenever capmatinib is used with a strong CYP450 3A4 inhibitor. Clinical and laboratory monitoring should be considered whenever a strong CYP450 3A4 inhibitor is added to or withdrawn from therapy with capmatinib, and the dosage adjusted as necessary based on clinical response and toxicity. Patients should be monitored for the development of adverse effects.

Drug and food interactions

Moderate

voriconazole food

Applies to: voriconazole

ADJUST DOSING INTERVAL: Food reduces the oral absorption and bioavailability of voriconazole. According to the product labeling, administration of multiple doses of voriconazole with high-fat meals decreased the mean peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) by 34% and 24%, respectively, when the drug is administered as a tablet, and by 58% and 37%, respectively, when administered as the oral suspension.

MANAGEMENT: To ensure maximal oral absorption, voriconazole tablets and oral suspension should be taken at least one hour before or after a meal.

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.
