Plasma Nevirapine Levels and 24‐Week Efficacy in HIV‐Infected Patients Receiving Nevirapine‐Based Highly Active Antiretroviral Therapy with or without Rifampicin

Abstract
Seventy human immunodeficiency virus (HIV)—infected patients receiving rifampicin and 70 HIV-infected patients not receiving rifampicin were enrolled to receive 400 mg of nevirapine-based highly active antiretroviral therapy per day. Mean plasma nevirapine levels at 8 and 12 weeks were lower in patients receiving rifampicin (P = .048). However, virological and immunological outcomes at 24 weeks were not different between the 2 groups (P > .05).
