Emtricitabine (commonly called FTC, systematic name 2',3'-dideoxy-5-fluoro-3'-thiacytidine[2]), with trade name Emtriva (formerly Coviracil), is a nucleoside reverse-transcriptase inhibitor (NRTI) for the prevention and treatment of HIV infection in adults and children. In 2019, it was the 494th most commonly prescribed medication in the United States, with more than 3 thousand prescriptions.[3]

HBV infection
Emtricitabine exhibits clinical activity against the hepatitis B virus (HBV), but is not approved by the U.S. Food and Drug Administration (FDA) for the treatment of HBV infection.[5] Among individuals with chronic HBV infection, emtricitabine treatment results in significant histologic, virologic, and biochemical improvement. The safety profile of emtricitabine during treatment is similar to that of a placebo. Emtricitabine, like all other FDA approved drugs, cures neither HIV nor HBV infection. In a study involving individuals with HBV infection, symptoms of infection returned in 23% of emtricitabine-treated individuals who were taken off therapy.[7] In studies involving individuals with chronic HIV infection, viral replication also resumes when study subjects are taken off therapy.[8] As with drugs used to treat HIV infection, drugs used to treat HBV infection may have to be used in combination to prevent the evolution of drug resistant strains. The effectiveness of emtricitabine in combination with other anti-HBV drugs has not been established.

History
Emtricitabine was discovered by Dennis C. Liotta, Raymond F. Schinazi, and Woo-Baeg Choi of Emory University and licensed to Triangle Pharmaceuticals by Emory in 1996.[9] Triangle Pharmaceuticals was acquired in 2003 by Gilead Sciences, which completed development and now markets the product with the brand name Emtriva.
It was approved by the FDA July 2, 2003.[10] It is very similar to lamivudine (3TC) and cross-resistance between the two is near-universal.[medical citation needed]
