Atazanavir Drug Information

Medication Information: Atazanavir is an antiretroviral drug. It is prescribed for Acquired Immune Deficiency Virus (HIV). Atazanavir slows the process of HIV infection but is not a definitive treatment. The HIV virus kills cells in the body called CD4 cells. These cells are white blood cells and are important because they protect the body against infections. If HIV is not treated, the body’s immune system gradually weakens and loses its ability to defend itself against bacteria, viruses and other microbes.

Atazanavir belongs to a group of antiviral drugs called protease inhibitors (PIs). Atazanavir is given in combination with a number of other antiretroviral drugs (antiretrovirals). Taking several different antiviral drugs at the same time is much more effective for treating HIV than prescribing just one type of medicine. Combination administration also significantly reduces the risk of viral resistance to drugs.

Atazanavir slows the progression of HIV by reducing the number of viruses in the body. This process strengthens the immune system and reduces the risk of HIV-related infections. This medicine can be prescribed by doctors who specialize in HIV.
