Interactions between your drugs

Major

boceprevir atrasentan

Applies to: boceprevir and atrasentan

GENERALLY AVOID: Coadministration with inhibitors of the hepatic influx transporters organic anion transporting polypeptides (OATP) 1B1 and/or 1B3 may increase the plasma concentrations and adverse effects of atrasentan. In clinical studies, coadministration with the OATP1B1 and 1B3 inhibitor cyclosporine increased the mean systemic exposure (AUC) and peak plasma concentration (Cmax) of atrasentan (single dose, 10 mg) by 380% and 430%, respectively. The risk of adverse effects such as edema, hepatotoxicity and anemia may be increased with this combination.

MANAGEMENT: Concomitant use of atrasentan with OATP1B1 and/or 1B3 inhibitors should generally be avoided.

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.
