Interactions between your drugs

Moderate

tenofovir capmatinib

Applies to: AccessPak for HIV PEP Basic (emtricitabine / tenofovir disoproxil) and capmatinib

GENERALLY AVOID: Coadministration with capmatinib may increase the plasma concentrations and risk of adverse effects of drugs that are substrates of P-glycoprotein (P-gp) and/or breast cancer resistance protein (BCRP) transporters, such as digoxin and rosuvastatin. The proposed mechanism is decreased clearance due to capmatinib-mediated inhibition of intestinal P-gp and/or BCRP efflux transport proteins. Coadministration with capmatinib increased the systemic exposure (AUC0-INF) and peak plasma concentration (Cmax) of digoxin (a P-gp substrate) by 47% and 74%, respectively. Concomitant use of capmatinib increased the AUC0-INF and Cmax of rosuvastatin (a BCRP substrate) by 108% and 204%, respectively.

MANAGEMENT: Coadministration of capmatinib with drugs that are substrates of P-gp and/or BCRP should generally be avoided. However, if concomitant use is unavoidable, caution is advised, particularly with drugs that have a narrow therapeutic range. Clinical and laboratory monitoring should be considered whenever capmatinib is added to or withdrawn from therapy with these drugs, and dosages adjusted as necessary. Patients should be monitored for the development of adverse effects.

Drug and food interactions

Minor

tenofovir food

Applies to: AccessPak for HIV PEP Basic (emtricitabine / tenofovir disoproxil)

Food enhances the oral absorption and bioavailability of tenofovir, the active entity of tenofovir disoproxil fumarate. According to the product labeling, administration of the drug following a high-fat meal increased the mean peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) of tenofovir by approximately 14% and 40%, respectively, compared to administration in the fasting state. However, administration with a light meal did not significantly affect the pharmacokinetics of tenofovir compared to administration in the fasting state. Food delays the time to reach tenofovir Cmax by approximately 1 hour. Tenofovir disoproxil fumarate may be administered without regard to meals.

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.
