    Bismuth subsalicylate (Pepto-Bismol, Kaopectate) helps to treat diarrhea by influencing how fluid is absorbed by intestines; it may also reduce inflammation and stop the growth of certain bacteria.
    Loperamide (Imodium, Kaopectate) treats diarrhea, but by a different method; it slows the movement of fluid through your intestines so that more fluid is absorbed.

    Simethicone (Gas-X, Mylanta Gas) helps control excess gas by allowing bubbles in the stomach and intestines to come together more easily, so your body can expel them quickly and with less distress.
