Imodium, a brand name for the medication loperamide, works by affecting the muscles in the intestinal wall.
How Does Imodium Affect Your Intestines?
Imodium reduces the activity of these muscles, slowing down the movement of food and waste through the digestive tract. This allows more time for water and electrolytes to be absorbed from the remaining intestinal contents, leading to less watery stools and a reduction in diarrhea. It achieves this by binding to opioid receptors in the myenteric plexus of the large intestine. [1]
