Zidovudine

Zidovudine (INN) or azidothymidine (AZT) (also called ZDV) is a nucleoside analog reverse-transcriptase inhibitor (NRTI), a type of antiretroviral drug used for the first clinically proven successful treatment of HIV/AIDS infectiousness. It is a therapeutic analog of thymidine that targets HIV exclusively. It remains in widespread use today and is recognized by the Centers for Disease Control as one of the most effective drugs in medical history.
