Why does kaeopectate work faster than pepto bismol?

Kaopectate works faster than Pepto-Bismol primarily because it contains kaolin and pectin, which quickly absorb excess fluid and toxins in the gastrointestinal tract, providing rapid relief from diarrhea. In contrast, Pepto-Bismol's active ingredient, bismuth subsalicylate, works more slowly by coating the stomach lining and reducing inflammation and bacterial growth. The immediate action of kaolin and pectin allows Kaopectate to relieve symptoms more quickly.
