Interactions between your drugs

Moderate

etravirine vonoprazan

Applies to: etravirine and Voquezna Dual Pak (amoxicillin / vonoprazan)

GENERALLY AVOID: Coadministration with moderate inducers of CYP450 3A4 may significantly decrease the plasma concentrations of vonoprazan, which is metabolized by the isoenzyme. When coadministered with moderate CYP450 3A4 inducers, vonoprazan systemic exposure (AUC) is predicted to decrease by 50%. Reduced efficacy of vonoprazan may occur.

MANAGEMENT: According to the manufacturer, concomitant use of vonoprazan with moderate CYP450 3A4 inducers should be avoided.

Drug and food interactions

Moderate

etravirine food

Applies to: etravirine

ADJUST DOSING INTERVAL: Coadministration with food increases the oral bioavailability of etravirine. The mechanism is unknown. Compared to administration following a meal, the systemic exposure (AUC) to etravirine was decreased by about 50% when the drug was administered under fasting conditions. The types of meal studied (ranging from 345 kilocalories containing 17 grams fat to 1160 kilocalories containing 70 grams fat) did not appear to make a difference with respect to impact on etravirine bioavailability.

MANAGEMENT: Etravirine should always be administered following a meal.
