Atazanavir atazanavir is a structural analog of the transition state during which the bond between a phenylalanine and proline is broken. Humans do not have any enzymes that break bonds between phenylalanine and proline, so this drug will not target human enzymes. Atazanavir is available as a 150 mg capsule, 200 mg capsule, 300 mg capsule, and 50 mg oral powder packet.

Atazanavir Atazanavir, sold under the trade name Reyataz among others, is an antiretroviral medication used to treat and prevent HIV/AIDS.
