Official title
A Phase IIB Study to Evaluate the Effects of Welchol (Colesevelam Hydrochloride) on Colonic Transit, Intestinal Permeability and Bowel Function in Diarrhea-predominant Irritable Bowel Syndrome (D-IBS)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Our hypothesis is that the medication approved for treatment of high blood cholesterol levels, Colesevelam HCl (WELCHOL), decreases colonic transit and permeability in patients with diarrhea due to irritable bowel syndrome. This effect is thought to result from the effect of the medication on bile acids, which can cause diarrhea.
