Pharmacology
Dual HIV NRTI combination; emtricitabine (FTC) and tenofovir alafenamide (TAF) each inhibit HIV-1 reverse transcriptase via nucleotide analog chain termination after intracellular phosphorylation, with TAF serving as a prodrug converted intracellularly to tenofovir and then to the active metabolite tenofovir diphosphate.
Enfuvirtide is an HIV-1 fusion inhibitor that binds to the first heptad-repeat (HR1) domain of the gp41 subunit of the viral envelope glycoprotein, preventing the conformational changes required for fusion of viral and cellular membranes and thereby blocking HIV-1 entry into CD4+ cells.
