Abstract

Etravirine (ETR) is a non-nucleoside reverse transcriptase inhibitor (NNRTI) with a potent and broad in vitro spectrum of activity against HIV-1 and viruses with NNRTI resistances, allowing sequential use of drugs of this family. The potency, efficacy and safety of etravirine have been demonstrated in multi-treated patients, but few data are available on first-line antiretroviral therapy (ART) and the role of this drug in initial treatment phases has not been defined. The presence of primary NNRTI resistances and those acquired during first-line therapy is increasingly frequent. Due to its genetic barrier and efficacy, ETR can form part of a second-line ART regimen in patients with failure to a first-line regimen. In the initial phases, adverse effects continue to be the main reason for modifying ART. ETR has demonstrated safety and tolerability, with no central nervous system adverse effects and a good liver, lipid and gastrointestinal safety profile. As with the other NNRTIs, the most common adverse effect is rash. Because of ETR good tolerability profile, this drug can be considered when a new treatment is required due to adverse effects. Because of the characteristics of ETR the possibility of once-daily administration and ...Continue Reading
