Mechanism of action

Lopinavir is a protease inhibitor that prevents the cleavage of HIV polyproteins, resulting in immature, non-infectious viral particles. Ritonavir is a potent protease inhibitor used as a pharmacokinetic booster to increase lopinavir levels. Raltegravir is an integrase strand transfer inhibitor (INSTI) that blocks the integration of HIV DNA into the host cell chromosome, preventing establishment of persistent infection.
