Etravirine (ETV, trade name: Intelence ® ; manufacturer: Tibotec ) is a drug used to treat HIV- infected patients as part of an HIV combination therapy .

Etravirine belongs to the class of non-nucleoside reverse transcriptase inhibitors (NNRTIs).

history

Intelence, in combination with other anti retroviral drugs, was approved for the treatment of HIV-1 infections in unsuccessful patients in the United States in January 2008 and in the European Union in August 2008.

pharmacology

Etravirine belongs to the class of non-nucleoside reverse transcriptase inhibitors (NNRTIs). The active ingredient binds non-competitively to the reverse transcriptase of HIV-I , near the substrate binding site for nucleosides . This blocks the catalytically active binding site. Only a few nucleosides can bind and the polymerization is slowed down significantly.

Side effects

In general, etravirine is well tolerated, although some studies reported the side effects typical of NNRTIs, dizziness and rash. However, the side effects rarely led to therapy discontinuation.

In mid-2009, the manufacturer announced that there had been a death from Lyell's syndrome and hypersensitivity reactions combined with liver failure .

Resistances

Compared to other NNRTIs, etravirine has the advantage that, in addition to being very effective against the wild type, it is also very effective against most NNRTI-resistant strains. In phase I / II studies, etravirine showed its high potency in lowering viral loads.
