Duralax is indicated for:

Pharmacology

Bisacodyl is a diphenolic compound, structurally related to phenolphthalein, and is widely used as a laxative. It works directly on the colon to stimulate peristalsis, and on both the small bowel and colon to increase the amount of water and electrolytes retained within the gut lumen. When it reaches the caecum, Bisacodyl triggers a response that extends throughout the entire colon.
