Description: Tenofovir alafenamide, also known as TAF and GS-7340, is a nucleotide reverse transcriptase inhibitor (NRTIs) and a novel prodrug of tenofovir. By blocking reverse transcriptase, TAF prevent HIV from multiplying and can reduce the amount of HIV in the body. Tenofovir alafenamide is a prodrug, which means that it is an inactive drug. In the body, tenofovir alafenamide is converted to tenofovir diphosphate (TFV-DP). Tenofovir alafenamide fumarate was approved in November 2015 for treatment of HIV-1.
