Interactions between your drugs

Moderate

darunavir capmatinib

Applies to: darunavir and capmatinib

MONITOR: Coadministration of capmatinib with moderate 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. Data are not available for other, less potent inhibitors.

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 Clinical and laboratory monitoring should be considered whenever a moderate CYP450 3A4 inhibitor is added to or withdrawn from therapy with capmatinib, and the dosage adjusted as necessary based on clinical response and toxicity.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

darunavir food

Applies to: darunavir

ADJUST DOSING INTERVAL: Food enhances the absorption and oral bioavailability of darunavir administered in combination with low-dose ritonavir. The mechanism is unknown. When administered with food, the peak plasma concentration (Cmax) and area under the plasma concentration-time curve (AUC) of darunavir were approximately 30% higher than when administered in the fasting state. Darunavir exposure was similar for the range of meals studied. The total caloric content of the various meals evaluated ranged from 240 Kcal (12 grams fat) to 928 Kcal (56 grams fat).

MANAGEMENT: To ensure maximal oral absorption, darunavir coadministered with ritonavir should be taken with food. The type of food is not important.

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.
