Etravirine (ETR,[3]), sold under the brand name Intelence is an antiretroviral medication used for the treatment of HIV.[1] Etravirine is a human immunodeficiency virus type 1 (HIV-1) non-nucleoside reverse transcriptase inhibitor (NNRTI).[1] Unlike agents in the class, resistance to other NNRTIs does not seem to confer resistance to etravirine.[4] Etravirine is marketed by Janssen, a subsidiary of Johnson & Johnson. In January 2008, the US Food and Drug Administration (FDA) approved its use for people with established resistance to other drugs, making it the 30th anti-HIV drug approved in the United States and the first to be approved in 2008.[5] It was also approved for use in Canada in April 2008.
