Atazanavir Sulfate is indicated for the treatment of HIV-1 infection in adults and pediatric patients. It is used as part of combination antiretroviral therapy (ART) and is not a cure for HIV but helps control viral replication.
As a protease inhibitor, Atazanavir works by inhibiting the HIV protease enzyme, which is essential for the assembly and maturation of infectious HIV particles. By blocking this enzyme, the medication prevents the virus from replicating effectively.
Atazanavir should be taken with food for optimal absorption. Common side effects include jaundice (yellowing of skin/eyes) due to increased bilirubin levels, nausea, and headache. Patients should be monitored for kidney stones and liver function. Drug interactions are common with many medications including certain statins, acid reducers, and antipsychotics. Resistance may develop if used inconsistently.
