Mechanism of Action
Reyataz binds to the HIV-1 protease and stops viral proteins from being cleaved, which is required for the maturation of the HIV-1 virus. Reyataz suppresses HIV-1 replication in vivo and prevents HIV-1 replication in cell culture.
Anti-protease agents, such as ritonavir
Reverse transcriptase inhibitors without nucleosides, such as efavirenz
Inhibitors of nucleoside reverse transcriptase, such as zidovudine
Several antacids, like aluminum hydroxide,
The gastrointestinal tract quickly absorbs reyataz, which reaches peak concentrations in 1-2 hours. Less than 5% of reyataz is minimally bound to plasma proteins. Following oral administration, there is an apparent volume of distribution of about 140 L. Reyataz undergoes conjugative metabolization to produce inactive metabolites. Atazanavir is metabolized primarily by the enzymes CYP3A4 and glucuronidation, according to in vitro studies. P-gp, but not BCRP, is a substrate for atazanavir. Atazanavir is primarily eliminated from the body through biliary elimination in the form of unchanged drug (57%) and conjugated metabolites (20%) in feces.
