Interactions between your drugs

Minor

boceprevir vibegron

Applies to: boceprevir and vibegron

Coadministration with moderate or potent inhibitors of CYP450 3A4 and/or P-glycoprotein (P-gp) may increase the plasma concentrations (AUC) of vibegron, which has been shown in vitro to be a substrate of the isoenzyme and transporter. Although CYP450 3A4 is the predominant enzyme in vibegron metabolism, metabolic pathways have only a minor role in the elimination of vibegron. In a phase 3 Japanese study, coadministration of vibegron (100 mg) with moderate (diltiazem) and potent (ketoconazole) inhibitors of CYP450 3A4, resulted in a 1.6- and 2.1-fold increase in vibegron AUC, respectively, which was not considered clinically significant. No dosage adjustment is recommended when vibegron is administered in combination with moderate or potent CYP450 3A4 and/or P-gp inhibitors.

Drug and food interactions

Moderate

boceprevir food

Applies to: boceprevir

ADJUST DOSING INTERVAL: Food significantly enhances the oral bioavailability of boceprevir. When given at 800 mg three times daily with food, boceprevir exposure increased by up to 65% relative to administration in the fasting state. The bioavailability of boceprevir was similar regardless of meal type (e.g., high-fat versus low-fat) or whether taken 5 minutes prior to eating, during a meal, or immediately following completion of the meal. Therefore, boceprevir may be taken without regard to either meal type or timing of the meal.

MANAGEMENT: To ensure maximal oral absorption, boceprevir should be administered with a meal or light snack.

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.
