Lopinavir is a potent HIV-1 protease inhibitor used in combination therapy with Ritonavir to treat HIV infection. It inhibits the HIV-1 protease enzyme, preventing cleavage of viral polyproteins and formation of mature infectious virions. Lopinavir provides high antiviral activity, favorable pharmacokinetics when boosted with Ritonavir, and is widely used in both treatment-naive and experienced patients.
1. Inhibits HIV-1 protease, preventing cleavage of Gag-Pol polyproteins.
2. Results in production of immature, non-infectious viral particles.
3. Boosted with Ritonavir to increase plasma concentrations via CYP3A4 inhibition.
4. Reduces viral load and improves CD4+ T-cell counts in infected patients.
