Coadministration of ketoconazole tablets with potent enzyme inducers of CYP3A4 may decrease the bioavailability of ketoconazole to such an extent that efficacy may be reduced.

Concomitant systemic use of itraconazole or ketoconazole and Etravirine may increase plasma concentrations of etravirine.

Simultaneously, plasma concentrations of itraconazole or ketoconazole may be decreased by Etravirine.
