Mechanism of action

Lopinavir is a potent HIV protease inhibitor that prevents the maturation of HIV virions by blocking the protease enzyme required to process viral proteins. Ritonavir is a second protease inhibitor included at low dose as a pharmacokinetic booster, inhibiting the metabolism of lopinavir and maintaining therapeutic plasma concentrations. Together, they reduce viral load and slow disease progression in HIV-infected patients.
