Loperamide Hydrochloride(Cat No.:A000269)is an over-the-counter antidiarrheal medication that works by slowing down gut motility. It acts on the opioid receptors in the intestinal wall, reducing the frequency of bowel movements and increasing the absorption of fluids and electrolytes. Loperamide is used to treat acute diarrhea, including traveler’s diarrhea, and chronic diarrhea associated with conditions like irritable bowel syndrome (IBS). It is generally well-tolerated, with minimal central nervous system effects due to its poor ability to cross the blood-brain barrier, making it a safe and effective option for diarrhea management.
