Mechanism of action

Atazanavir is a protease inhibitor that binds to the active site of HIV protease, an enzyme essential for processing viral precursor proteins into functional components. By blocking this enzymatic activity, the drug prevents the formation of mature, infectious viral particles, thereby reducing viral replication and slowing disease progression. It is typically used as part of combination antiretroviral therapy (cART) in HIV-infected patients.
