Bisacodyl is a diphenolic compound. Its chemical structure is similar to that of phenolphthalein. It is widely used as a laxative. Bisacodyl acts on the colon to stimulate peristalsis and on the small bowel and colon to increase intraluminal water and electrolytes. When applied to the caecum, Bisacodyl initiates a response in the entire colon.
