Possible SEO-optimized article on Reyataz: Reyataz (atazanavir sulfate) is an antiretroviral medication used to treat HIV infection in adults and pediatric patients weighing at least 15 kg (33 lbs). Reyataz is a protease inhibitor that works by blocking the activity of an enzyme (protease) that HIV needs to make more copies of itself. Reyataz is usually taken with other HIV drugs as part of a combination therapy, also known as antiretroviral therapy (ART), which aims to suppress the virus and improve the immune function of the person living with HIV.

Reyataz is available in different formulations and strengths, including capsules and powder for oral suspension. The recommended dosage and frequency of Reyataz depend on several factors, such as the patient's age, weight, renal function, and other drugs they are taking.

Dosage of Reyataz The initial dose of Reyataz for adults and pediatric patients weighing at least 40 kg (88 lbs) is one 300 mg capsule once daily, boosted by ritonavir (Norvir) 100 mg once daily or 200 mg twice daily.
