History

Stavudine was approved by the Food and Drug Administration (FDA) in Jun 24, 1994 for adults and in Sep 6, 1996 for pediatric use and again as an extended-release version for once-a-day dosing in 2001. The fourth antiretroviral drug on the market, its patent will expire in the United States on 2008-06-25.

Mechanism of ation

Stavudine is an analog of thymidine. It is phosphorylated by cellular kinases into active triphosphate. Stavudine triphosphate inhibits the reverse transcriptase by competing with natural substrate, thymidine triphosphate. It also causes termination of DNA synthesis by incorporating into it.

The oral absorption rate of stavudine is over 80 %. Approximately half of stavudine is actively secreted unchanged into the urine and the other half is eliminated through endogenic pathways. Simultaneous use of AZT is not recommended, for AZT can inhibit the intracellular phosphorylation of stavudine. Other anti-HIV drugs do not possess this property. The main severe side effect is peripheral neuropathy, which can be corrected by reducing dosage. Stavudine has been shown in laboratory test to be genotoxic, but with clinical doses its carcinogenic effects are non-existent.

Lactic Acidosis in Pregnancy - Brief Article
From Family Pratice News, 2/1/01

Three cases of fatal lactic acidosis occurred in pregnant women who used stavudine and didanosine with other anti-HIV drugs, the Food and Drug Administration warned health care professionals.

"The combination of stavudine (Zerit) and didanosine (Videx or Videx EC) should be used with caution during pregnancy and is recommended only if the potential benefit clearly outweighs the potential risk, such as when there are few remaining treatment options," Bristol-Myers Squibb said in a letter to health care providers. Women using the drug combination should be monitored closely for signs of lactic acidosis and liver damage.

Lactic acidosis is a well-described complication of nucleoside analogues, and pancreatitis is a known side effect of stavudine and didanosine. Black box product label warnings have been strengthened.
