How it works
ImodiumQuestranPepto BismolPepto Bismol
Imodium (Loperamide) is an antidiarrheal medicine. It's actually an opioid related to morphine, though it doesn't affect the brain like opioid pain medicines do. Instead, it works directly on muscles in your large intestine to stop contractions and increase the time it takes for stool to move through. The result is less diarrhea and more formed stool.Coming soon.Pepto Bismol (Bismuth Subsalicylate) is a stomach and intestine medicine with multiple effects. It relieves diarrhea by helping your intestines absorb water and electrolytes, and by lowering intestine inflammation and movement. It also has antibacterial and antacid effects.Pepto Bismol (Bismuth Subsalicylate) is a stomach and intestine medicine with multiple effects.
