Pharmacology
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.
Ritonavir is a peptidomimetic inhibitor of the HIV-1 protease that renders the enzyme incapable of processing the Gag-Pol polyprotein precursor, leading to production of non-infectious immature HIV particles; it also potently inhibits CYP3A and, to a lesser extent, CYP2D6, significantly affecting plasma concentrations of many co-administered drugs.
