Interactions between your drugs

Major

etravirine capivasertib

Applies to: Intelence (etravirine) and capivasertib

Consumer information for this interaction is not currently available.

GENERALLY AVOID: Coadministration with moderate inducers of CYP450 3A4 may significantly decrease the plasma concentrations and pharmacologic effects of capivasertib. The proposed mechanism is accelerated clearance of capivasertib due to induction of the CYP450 3A4 isoenzyme, which is the primary route of elimination of capivasertib. Based on clinical studies and model-informed approaches, concomitant use with the potent CYP450 3A4 inducer rifampin is predicted to decrease capivasertib systemic exposure (AUC) by 70% and peak plasma concentration (Cmax) by 60%. Coadministration with the moderate CYP450 3A4 inducer efavirenz, is predicted to decrease capivasertib AUC by 60% and Cmax by 50%. Reduced therapeutic efficacy of capivasertib may occur.

MANAGEMENT: Coadministration of capivasertib with moderate CYP450 3A4 inducers should generally be avoided. However, some authorities advise caution and monitoring for reduced therapeutic efficacy with their concomitant use. Consultation of individual product labeling is advisable for further guidance.
