Consumer:Consumer information for this interaction is not currently available.CONTRAINDICATED: Coadministration with drugs that are strong inducers of CYP450 3A4 may decrease the plasma concentrations of ritonavir and result in a potential loss of virologic response. The proposed mechanism is increased clearance due to induction of CYP450 3A4, which is the isoenzyme primarily responsible for the metabolism of ritonavir. MANAGEMENT: Given the risk of reduced viral susceptibility and resistance development associated with subtherapeutic antiretroviral drug levels, concomitant use of ritonavir with drugs that are strong inducers of CYP450 3A4 is considered contraindicated.
