SAN DIEGO, May 18 /PRNewswire/ -- New study results indicated that treatment with AMITIZA(R) (lubiprostone) 8 mcg lead to significant relief of overall symptoms of Irritable Bowel Syndrome with Constipation (IBS-C). These results were presented at Digestive Disease Week (DDW) 2008, the largest annual international meeting of digestive disease specialists.

Chey, M.D., primary investigator of the study, University of Michigan Health System. "These data are important because they show that in studies, AMITIZA has demonstrated the ability to improve the overall symptoms reported by patients with IBS-C."

AMITIZA 8 mcg was approved by the U.S. Food and Drug Administration (FDA) on April 29, 2008 for the treatment of IBS-C in women 18 years of age and older, and has been approved since 2006 at a 24 mcg dose for the treatment of Chronic Idiopathic Constipation in adults. These data were among others presented at DDW 2008 that evaluated the effect of AMITIZA for IBS-C.
