Interactions between your drugs

Moderate

boceprevir abametapir topical

Applies to: boceprevir and abametapir topical

GENERALLY AVOID: Based on in vitro inhibition data, a single topical application of abametapir lotion may increase plasma concentrations of drugs that are substrates of CYP450 3A4, CYP450 2B6, and CYP450 1A2 isoenzymes and increase their systemic concentrations. The proposed mechanism is high and prolonged systemic exposure to the metabolite abametapir carboxyl, which has been shown to be an in vitro inhibitor of CYP450 3A4, CYP450 2B6, and CYP450 1A2. The mean half-life of abametapir carboxyl in adults is estimated to be 71 hours or longer.

MANAGEMENT: Use of CYP450 3A4, CYP450 2B6, and CYP450 1A2 substrates should generally be avoided within 2 weeks after topical application of abametapir lotion. If this is not feasible, the manufacturer recommends avoiding use of abametapir lotion. If abametapir is used, monitor for increased toxicity of the CYP450 3A4, CYP450 2B6, and/or CYP450 1A2 substrate.

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.
