Question

Quizplus · Accepted Answer

Loperamide (Imodium) is an example of an opiate-related antidiarrheal agent. It works by slowing down the movement of the intestines and decreasing the amount of fluid released into the bowel, resulting in less frequent and more formed stools. Bismuth subsalicylate (Pepto-Bismol) and kaolin and pectin (Kaopectate) are examples of adsorbent antidiarrheal agents, which work by binding to and absorbing toxins and bacteria in the gut. Bisacodyl (Dulcolax) is a laxative, not an antidiarrheal agent.
