Atazanavir + Ritonavir

Atazanavir + Ritonavir is a combination of two antiviral medicines used to treat Human Immunodeficiency Virus (HIV) infection. Atazanavir is a protease inhibitor that prevents the virus from multiplying, while Ritonavir enhances the effectiveness of Atazanavir by increasing its levels in the blood. This combination helps control HIV, improving immune function and reducing the risk of developing HIV-related complications. Though it is not a cure for HIV or AIDS, it significantly improves the quality of life when taken regularly as prescribed. It is usually taken with other antiretroviral drugs as part of combination therapy.
