Mechanism of action
Lopinavir is a potent HIV protease inhibitor that binds to the active site of HIV protease, preventing the maturation of viral particles. Ritonavir is a second protease inhibitor included at lower doses as a pharmacokinetic booster, inhibiting cytochrome P450 metabolism and significantly increasing lopinavir plasma concentrations. Together, they suppress HIV replication by preventing the production of infectious viral particles.
