Atazanavir
Atazanavir is an antiretroviral protease inhibitor that is used in the therapy and prevention of human immunodeficiency virus (HIV-1) infection and the acquired immunodeficiency syndrome (AIDS). Atazanavir can cause transient and usually asymptomatic elevations in serum aminotransferase levels, mild elevations in indirect bilirubin concentration and, rarely, clinically apparent, acute liver injury. In HBV or HCV coinfected patients, highly active antiretroviral therapy with atazanavir may result of an exacerbation of the underlying chronic hepatitis B or C.
