Frequently Asked Questions

Atazanavir and ritonavir are used together to treat HIV-1 infection. Atazanavir is a protease inhibitor, and ritonavir is used in a low dose to boost atazanavir levels, helping reduce viral load and improve immune function as part of combination antiretroviral therapy.

This combination is made from two antiretroviral agents: atazanavir sulfate, a protease inhibitor, and ritonavir, another protease inhibitor used as a pharmacokinetic enhancer to increase atazanavir's effectiveness.

The commonly known trade name for the fixed-dose combination is not globally standardized, but the regimen is often used clinically as “Atazanavir boosted with Ritonavir.” Atazanavir alone is branded as Reyataz.

Atazanavir (Reyataz) is manufactured by Bristol-Myers Squibb (BMS). Ritonavir (Norvir) is manufactured by AbbVie. Many generic manufacturers produce the combination for various markets.

The generic name is atazanavir and ritonavir.

While no single fixed-dose brand is universally marketed, the individual brands are Reyataz (atazanavir) and Norvir (ritonavir). In practice, the combination is referred to as atazanavir/ritonavir.

Manufacturing occurs in multiple approved facilities across the USA, Europe, and India, depending on the innovator or generic manufacturer supplying the product.
