Antidiarrheal Drugs
Loperamide
Loperamide works by acting on mu-opioid receptors in the gut to slow down the movement of the gut, which in turn, slows down contractions in the intestines. This allows more time for fluids and nutrients to be absorbed back into the body, which makes the stool less watery and decreases the number of times you go to the toilet.
Pepto-Bismol
Pepto-Bismol is used to treat diarrhea, nausea, heartburn, indigestion, gas, or upset stomach. Pepto-Bismol works as an antacid to reduce excess stomach acid and so eases discomfort. It also works to protect the stomach and lower part of your food pipe (esophagus) from stomach acid.
