Interactions between your drugs

Moderate

butabarbital maribavir

Applies to: belladonna / butabarbital and maribavir

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations of maribavir, which is primarily metabolized by the isoenzyme. When maribavir (400 mg twice daily) was administered with the potent CYP450 3A4 inducer, rifampin (600 mg once daily), maribavir peak plasma concentration (Cmax) and systemic exposure (AUC) decreased by 39% and 60%, respectively. The interaction has not been studied with other, less potent inducers.

MANAGEMENT: The potential for diminished pharmacologic effects of maribavir should be considered during coadministration with CYP450 3A4 inducers. Alternative treatments may be required if an interaction is suspected.
