Atazanavir 300mg and Ritonavir 100mg Tablets IP – Uses
Atazanavir and Ritonavir combination tablets are primarily used in the management of Human Immunodeficiency Virus (HIV) infection. This fixed-dose combination is a part of antiretroviral therapy (ART) that helps control the viral load and improve immune function (CD4 count) in HIV-positive individuals. It is not a cure for HIV, but it significantly reduces the risk of HIV-related complications and opportunistic infections.
How Atazanavir and Ritonavir works
Atazanavir is a protease inhibitor (PI) that blocks the action of HIV protease enzyme, which is essential for the virus to multiply. Ritonavir, also a protease inhibitor, is used in this combination as a pharmacokinetic booster. It inhibits the liver enzyme (CYP3A4) that metabolizes atazanavir, thereby increasing atazanavir levels in the blood and allowing once-daily dosing. This dual action helps suppress viral replication and reduces the viral load in the body.
Common side effects of Atazanavir and Ritonavir
- Nausea, vomiting, or diarrhea
- Headache or dizziness
- Abdominal pain or indigestion
- Yellowing of skin or eyes (jaundice) due to increased bilirubin
- Changes in body fat distribution (lipodystrophy)
- Increased blood sugar or lipid levels
Most side effects are manageable and often subside with time. However, if any side effect persists or worsens, consult your doctor.
