Raw research findings for this medication. Mostly single studies, not curated or confirmed robust.
Emtricitabine (FTC) is a nucleoside reverse transcriptase inhibitor closely related to lamivudine: it is built into viral DNA and stops it from growing. It is part of most tenofovir-based HIV combination tablets, such as Truvada, Descovy and Biktarvy, used for treatment and for pre-exposure prophylaxis (PrEP). It is sold on its own as Emtriva.
Emtricitabine is cleared mostly unchanged by the kidneys. The gene study listed looked at ABCC2, a transporter, for its levels. The evidence is weak, and there is no CPIC or DPWG guideline.
