Pharmacology
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.
Raltegravir inhibits the catalytic activity of HIV-1 integrase, an HIV-1-encoded enzyme required for viral replication, preventing integration of unintegrated linear HIV-1 DNA into the host cell genome; it is eliminated primarily via UGT1A1-mediated glucuronidation and does not inhibit or induce cytochrome P450 enzymes.
