title: Once-daily nevirapine XR: a brief overview of the safety and efficacy of a new formulation.
abstract: Nevirapine (NVP) was the first nonnucleoside reverse transcriptase inhibitor (NNRTI) approved by the US Food and Drug Administration (FDA) in 1996, for the treatment of HIV infection. Current treatment guidelines include NVP as a component of a recommended alternative NNRTI regimen, which may be the preferred regimen for patients with established cardiovascular risk factors since NVP has minimal untoward effects on serum lipids. Two randomized and controlled clinical trials established the noninferior virologic efficacy of twice-daily NVP versus ritonavir-boosted atazanavir (ATV/r), a protease inhibitor with limited effects on serum lipids, each drug on a background regimen of once-daily (QD) tenofovir (TDF)/emtricitabine (FTC). An extended-release (XR) formulation of NVP was developed since QD dosing and reduced pill burdens have been shown to improve regimen adherence. This formulation (Viramune XR 400 mg) was recently FDA approved based on the results of 2 randomized, controlled clinical trials. The XR formulation will provide additional treatment options for patients who may benefit from NVP-based regimens.
