Atazanavir-Ritonavir is a combination of 2 medicines: Atazanavir and Ritonavir. These drugs belong to the category of protease inhibitors. They work by inhibiting the protease enzyme production, which is needed by the HIV-infected cells to make new viruses. This effect assists to inhibit viral replication.
