Antidiarrheal Agents

Antidiarrheal agents may have antisecretory and antimicrobial action.

Bismuth subsalicylate (Pepto Bismol, Pink Bismuth, Kaopectate Extra Strength)

This is a highly insoluble salt of trivalent bismuth and salicylic acid. Greater than 80% of salicylic acid is absorbed from oral doses of bismuth subsalicylate chewable tablets. It controls diarrhea by reducing fluid secretion into the intestinal lumen, by binding bacterial toxins, or by acting as an antimicrobial agent.
