Objective: Simple methods for the determination of zidovudine (AZT), stavudine (d4T), lamivudine (3TC) and indinavir (INV) in human plasma by reversed-phase liquid chromatography (HPLC) with UV detection were described and validated.

Method: Solid-liquid extraction procedures were applied to the samples prior to analysis. Chromatography was performed on a C-18 analytical columns and the retention time ranged from 6.

Objective: The present study describes the determination of the bioequivalence of two different nevirapine tablet formulations (nevirapine tablets 200 mg, Novatec, as the test formulation vs. viramune tablets 200 mg, Boehringer Ingelheim, as the reference formulation).

Method: A single 200 mg oral dose of each preparation was administered to 11 human immunodeficiency virus (HIV)-infected patients volunteers and their bioequivalence was assessed by comparing the both plasma nevirapine concentrations-time curves and others pharmacokinetic parameters.

Over the last few years, a relative decline of the morbidity and mortality of human immunodeficiency virus (HIV) infection in industrialised countries has been observed due to the use of a potent combined therapy known as high active antiretroviral therapies (HAARTs). It has led to a decrease of viral load and a quantitative and qualitative improvement of immune function in patients, especially CD4+ T-lymphocyte count, having as a consequence a decrease of infectious complications and a global clinical improvement. Besides the positive effects of HAARTs on immune and metabolic alterations during HIV infection, it has been reported that the commonly used drugs AZT, ddI, and ddC are toxic to hepatocytes.
