Plasma lipid concentrations after 1.5 years of exposure to nevirapine or efavirenz together with stavudine and lamivudine

OBJECTIVES: To assess long-term changes in lipids and lipoproteins concentrations associated with exposure to non-nucleoside reverse transcriptase inhibitors. METHODS: Long-term analysis of plasma lipid concentrations was performed in patients …

Long-term experience with combination antiretroviral therapy that contains nelfinavir for up to 7 years in a pediatric cohort

OBJECTIVE: We sought to provide long-term data on the clinical, immunologic, and virologic response to highly active antiretroviral therapy in infants and children who are naive to protease inhibitors. METHODS: HIV-1-infected children who were naive …

Pharmacokinetic parameters of nevirapine and efavirenz in relation to antiretroviral efficacy

Optimal adherence is essential for successful antiretroviral therapy. We analyzed the relation between minimum plasma drug concentration (Cmin) and total drug exposure over 24 hr (AUC24) with virologic failure for therapy-adherent patients in the …

Pharmacokinetics of nevirapine: once-daily versus twice-daily dosing in the 2NN study

OBJECTIVE: As part of the large international, randomized 2NN trial, the pharmacokinetics of nevirapine in once-daily 400 mg and twice-daily 200 mg dosing regimens were investigated. METHOD: Treatment-naive HIV-1-infected patients were randomized to …

Plasma HIV-1 RNA decline within the first two weeks of treatment is comparable for nevirapine, efavirenz, or both drugs combined and is not predictive of long-term virologic efficacy: A 2NN substudy

BACKGROUND: The initial rate of plasma HIV-1 RNA (pVL) decline has been proposed as a marker of early efficacy of antiretroviral therapy (ART) and a possible predictor of late efficacy. We compared the rate of pVL decline in patients starting ART …

Nevirapine and efavirenz pharmacokinetics and covariate analysis in the 2NN study

OBJECTIVE: The aim of this 2NN pharmacokinetic substudy was to investigate the population pharmacokinetics of nevirapine and efavirenz. METHODS: Treatment-naive, HIV-1-infected patients received nevirapine (once or twice daily), efavirenz or a …

A randomized trial to study first-line combination therapy with or without a protease inhibitor in HIV-1-infected patients

OBJECTIVE: To compare one protease inhibitor (PI)-based and two PI-sparing antiretroviral therapy regimens. METHODS: International, open label, randomized study of antiretroviral drug-naive patients, with CD4 lymphocyte counts textgreater/= 200 x 106 …
