Atazanavir is an antiviral medication that prevents human immunodeficiency virus (HIV) cells from multiplying in your body. Atazanavir is used with other medications to treat HIV, which causes the acquired immunodeficiency syndrome (AIDS). Atazanavir is not a cure for HIV or AIDS. Atazanavir may also be used for purposes not listed in this medication guide.
Atazanavir, also known as Reyataz, has been used as an antiretroviral in treating HIV along with other medicines. Besides being a protease inhibitor, Atazanavir has relatively insignificant effects on a patient's lipid composition. Atazanavir can also be reinforced with other drugs like ritonavir for improved performance. However, those with acute liver complications and those taking sildenafil for pulmonary arterial hypertension are strongly advised against using Atazanavir.
