Blood samples for plasma concentrations were obtained at predose and at specific timepoints up to 48 hours after dosing on Days 1, 8, 15, 22, and 29. Cmax was derived from plasma concentration versus time data.
Blood samples for plasma concentrations were obtained at predose and at specific timepoints up to 48 hours after dosing on Days 1, 8, 15, 22, and 29. AUC(0-T) and AUC(INF) were derived from plasma concentration versus time data.
Tasting atazanavir (15 mg, administered as a 5 mL oral suspension) was defined as taking the sample into the mouth, swishing it across the tongue for approximately 30 seconds without swallowing, and then spitting it out. Immediately after tasting each treatment, participants scored the treatments for sweetness using a subjective sweet intensity scoring system: 0=not sweet, 1=mildly sweet, 2=moderately sweet, 3=very sweet. Participants were permitted to select a whole or half score number (for example, 1.5) between the minimum score of 0 and the maximum score of 3.0. The higher the score, the greater the sweetness.

Atazanavir is used for the treatment of HIV infections, including HIV in adults and Human Immunodeficiency Virus Type 1 (HIV-1) infection. It is a small molecule developed by Bristol-Myers Squibb Company for the infectious disease therapeutic area.
Atazanavir is a protease inhibitor used against HIV. It works by inhibiting the HIV protease enzyme, which is essential for the virus to mature and become infectious. This mechanism helps reduce viral replication in people with HIV infections.
Atazanavir is developed by Bristol-Myers Squibb Company, which trades under the ticker BMY. The company is conducting clinical research on this small molecule for the treatment of HIV infections.
Atazanavir is in Phase 3 clinical development. It is an investigational drug for HIV infections and is not yet approved by regulatory authorities. The development program includes completed trials across multiple phases.
Atazanavir has been studied in clinical trials including NCT00135434, NCT00357240, NCT00365339, and NCT00393328. These trials investigated its effects on glucose and insulin metabolism, drug interactions with proton pump inhibitors and famotidine, and bioequivalence of its 300 mg capsule formulation.
Atazanavir is the generic name for the drug also known as Reyataz. It is an HIV protease inhibitor developed by Bristol-Myers Squibb Company for the treatment of HIV infections in adults.
