Zidovudine
Zidovudine, also known as AZT (AZT), is a medication used to prevent and treat HIV/AIDS. It is an antiretroviral drug that belongs to a class of medications called reverse transcriptase inhibitors. Zidovudine works by blocking the reverse transcriptase enzyme, which is essential for the replication of HIV (human immunodeficiency virus). By inhibiting this enzyme, zidovudine prevents the virus from replicating and reduces the amount of virus in the body. This helps to slow down the progression of HIV to AIDS and also prevents the transmission of HIV from mother to child during pregnancy and childbirth.
