Terms & Properties

Preferred Name: Loperamide Hydrochloride

Definition: The hydrochloride salt form of loperamide, a synthetic, piperidine derivative and opioid agonist with antidiarrheal activity. Loperamide acts on the mu-receptors in the intestinal mucosa. This leads to a decrease in gastrointestinal motility by decreasing the circular and longitudinal smooth muscle activity of the intestinal wall. This slows intestinal transit and allows for more water and electrolyte absorption from the intestines. Loperamide is not significantly absorbed from the gut and does not cross the blood-brain barrier. Therefore it has no central nervous system effects.

NCI-GLOSS Definition: A drug used to treat diarrhea. Imodium slows the movement of the muscles in the small intestine to allow more water to be taken out of the feces (waste matter) and more nutrients to be absorbed.
