Ritonavir, sold under the brand names Norvir® and Norvir Sec®, and as a mixture with Lopinavir called Kaletra®, is a protease inhibitor used to treat HIV/AIDS by disrupting the reproductive cycle of the virus. Ritonavir binds to and inhibits the HIV-1 viral proteinase enzyme which prevents cleavage of the gag-pol polyprotein, resulting in noninfectious, immature viral particles. Protease inhibitors like ritonavir are almost always used in combination with at least two other anti-HIV drugs.

Chemistry
