Irritable Bowel Drug Lotronex Yanked By FDA

Alosetron (Lotronex) was approved for marketing by the FDA in February, 2000, but was withdrawn from the market in November, 2000, because of serious, life-threatening, gastrointestinal side effects. In June 2002, it was approved again by the FDA for marketing but in a restricted manner as part of a drug company-sponsored program for managing the risks associated with treatment. Use of alosetron is allowed only among women with severe, diarrhea-predominant, irritable bowel syndrome (IBS) who have failed to respond to conventional treatment for IBS.

The original official FDA statement issued when alosetron was originally withdrawn is below.
