 In addition, FTC in combination with tenofovir disoproxil fumarate (Truvada) was approved as a prophylactic drug (part of PrEP) to prevent transmission of HIV, further broadening its utility beyond HIV-infected individuals to that of prophylaxis, underscoring a novel and previously unmet need with ramifications for global health worldwide.Today, this drug is widely used as part of fixed-dose combination drug regimens, including Truvada, Atripla, Complera, Stribild, Descovy, Genvoya, Stribild, Odefsey, and Eviplera.Like 3TC, FTC was found to be active against HBV, but was never approved for this indication by the US FDA.
