title: Nevirapine levels after discontinuation of rifampicin therapy and 60-week efficacy of nevirapine-based antiretroviral therapy in HIV-infected patients with tuberculosis.
abstract: Seventy patients with human immunodeficiency virus (HIV) and tuberculosis coinfection who initiated nevirapine-based antiretroviral therapy and had trough nevirapine levels determined while receiving rifampicin were enrolled in a study. After discontinuation of rifampicin therapy, mean nevirapine levels (+/- standard deviation) increased from 5.4+/-3.5 mg/L to 6.4+/-3.4 mg/L (P=.047), but no nevirapine-related adverse events occurred. There was no statistically significant difference in 60-week antiviral efficacy between these patients and patients receiving nevirapine-based antiretroviral therapy alone (P>.05).
