An inhibitor of HIV reverse transcriptase
Stavudine is an inhibitor of HIV reverse transcriptase and a derivative of the nucleoside thymidine .1 It inhibits HIV-1 replication in human peripheral blood mononuclear cells (PBMCs; EC50 = 8.8 nM). Stavudine reduces the synthesis of HIV-specific antigen in MT-4 cells when used at concentrations ranging from 0.1 to 10 ?g/ml and reduces HIV-induced plaque formation in MT-4 cells at 0.05 ?g/ml.2 It reduces plasma- and cell-associated viral load in macaques infected with a highly pathogenic isolate of HIV-2.3 Stavudine induces sustained hind paw mechanical allodynia in a rat model of antiretroviral toxic neuropathy (ATN) when administered at a dose of 75 mg/kg twice weekly for five consecutive doses for a cumulative dose of 375 mg/kg.4 Formulations containing stavudine, in combination with other antiretrovirals, have been used in the treatment of HIV-1 infection.
