A patient taking bisacodyl asks the nurse how the medication works. The nurse knows that bisacodyl:


•Bisacodyl is a stimulant laxative that acts on the myenteric plexus to stimulate colonic mass movements.

•Bisacodyl is also a contact laxative, increasing fluid and electrolyte secretion.

•Bisacodyl is not osmotic. It does not reduce stool surface tension, nor is it bulk-forming.
