Metabolisme In vitro- forsøg med humane levermikrosomer indikerer, at etravirin primært gennemgår oxidativ metabolisme via det hepatiske cytokrom CYP450- system (CYP3A) og i mindre grad via CYP2C - gruppen efterfulgt af glucuronidation.
Metabolism In vitro experiments with human liver microsomes (HLMs) indicate that etravirine primarily undergoes oxidative metabolism by the hepatic cytochrome CYP450 (CYP3A) system and, to a lesser extent, by the CYP2C family, followed by glucuronidation.
