General description
Efavirenz, commercially known as Sustiva™ is a polycyclic aromatic hydrocarbon with benzene and oxazinan-2-one chromophores.
Application
Efavirenz has been used:
- to assess its anti-porcine endogenous retrovirus (PERV) activity
- in cytotoxicity assay
- to investigate the solute-solvent effects of efavirenz by means combined time-dependent density functional theory (TD-DFT) and spectroscopic calculations
Biochem/physiol Actions
Efavirenz is a nonnucleoside reverse transcriptase inhibitor (NNRTI). It is an anti-HIV drug, commonly used in combination therapy for AIDs treatment. It is part of highly active antiretroviral therapy (HAART) for the treatment of a human immunodeficiency virus (HIV) type 1.
Efavirenz is a nonnucleoside reverse transcriptase inhibitor (NNRTI); anti-retroviral.

Efavirenz is an inducer of drug metabolism enzymes. We studied the effect of efavirenz and ritonavir-boosted darunavir on serum unconjugated and conjugated bilirubin, as probes for UGT1A1 and bile transporters. Healthy volunteers were enrolled in a clinical trial. There were

U.S. HIV treatment guidelines recommend branded once-daily, 1-pill efavirenz-emtricitabine-tenofovir as first-line antiretroviral therapy (ART). With the anticipated approval of generic efavirenz in the United States, a once-daily, 3-pill alternative (generic efavirenz, generic lamivudine, and tenofovir) will decrease cost but may

Efavirenz (EFV) is one of the most commonly prescribed antiretroviral drugs (ARVs) for the treatment of HIV. Highly protein-bound drugs, like EFV, have limited central nervous system (CNS) penetration when measured using total drug concentration gradients between blood plasma (BP)
