AZT, azidothymidine, is an antiviral drug used to check the viral population by blocking the process of reproduction. The azidothymidin is particularly effective against human immunodeficiency virus (HIV) as this drug inhibits the activity of reverse transcriptase which is required for the formation of a DNA copy of the RNA genome of the virus.
