Pharmacology
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.
Odefsey is a fixed-dose combination of emtricitabine (an NRTI that inhibits HIV-1 reverse transcriptase by chain termination), rilpivirine (an NNRTI that non-competitively inhibits HIV-1 reverse transcriptase), and tenofovir alafenamide (a prodrug that is converted to tenofovir, an NRTI inhibiting HIV-1 reverse transcriptase by chain termination).
