(Also known as Stavudine and Zerit). d4T is a dideoxynucleoside pyrimidine
analog (2'3'-didehydro-3'-deoxythymidine). Like other nucleoside analogs, d4T inhibits HIV replication by inducing premature viral
DNA chain termination. d4T has been approved for patients with advanced HIV
infection intolerant to or failing other antiretroviral drugs. See also
