Atazanavir is an antiretroviral drug that is used to control, prevent, and treat HIV or AIDS patients. This drug is only effective against human immunodeficiency virus Type 1. It does not possess any effect on the type 2 virus.
This drug is considered as one of the best antiretroviral medicines as it binds to the active site of HIV-1 protease. When the protease activity of the human immunodeficiency virus is blocked it is unable to multiply and regulate the machinery of the host thus it is no more harmful. The human immunodeficiency virus becomes inactive and can not cause acquired immunodeficiency syndrome (AIDS).
