Description and Uses

Stavudine, a dideoxynucleoside analog of thymidine, has been introduced in the U.S.A. for the treatment of late-stage AIDS patients who are refractory to other AIDS treatments. Similar as other currently available agents for AIDS treatment such as zidovudine (AZT), didanosine, and zalcitabine, the anti-HIV activity of these 2'3'- dideoxynucleosides is ascribed to the inhibitory effect of their corresponding 5'- triphosphates against the HlVsncoded RNAdependent DNA polymerase (reverse transcriptase). While some of these drugs have rapid development of drug resistance, stavudine is active against AZT-resistant HIV strains. It has a favorable pharmacokinetic profile with more complete and less variable oral absorption than AZT and didanosine and has a bioavailability of 80-90%.
