Edit list (add/remove drugs)

Interactions between your drugs

Moderate

brentuximab vedotin simeprevir

Applies to: brentuximab and simeprevir

MONITOR: Coadministration with inhibitors of P-glycoprotein (P-gp) may increase the plasma concentrations of monomethyl auristatin E (MMAE), the microtubule-disrupting component of brentuximab vedotin. In vitro, MMAE was found to be a substrate of the P-gp efflux transporter.

MANAGEMENT: Caution is advised when brentuximab is used with P-gp inhibitors. Close monitoring for adverse effects including neutropenia, infection, peripheral neuropathy, and hepatotoxicity is recommended.

Drug and food interactions

Moderate

simeprevir food

Applies to: simeprevir

ADJUST DOSING INTERVAL: Food significantly enhances the oral bioavailability of simeprevir, although the type of food does not seem to matter. In healthy study subjects, administration of simeprevir after a high-fat, high-caloric (928 kcal) breakfast increased systemic exposure (AUC) by 61% and delayed absorption by 1 hour, while administration after a normal caloric (533 kcal) breakfast increased AUC by 69% and delayed absorption by 1.5 hours.

MANAGEMENT: To ensure maximal oral absorption, simeprevir should be administered with food.

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.
