Loperamide hydrochloride
Loperamide hydrochloride (CAS 34552-83-5, C29H33ClN2O2 · HCl) is a synthetic piperidine derivative and opioid agonist. It acts peripherally on the mu-opioid receptors in the myenteric plexus of the large intestine. This action reduces intestinal motility and fluid secretion, making it primarily used for symptomatic treatment of acute and chronic diarrhoea. Available from Tech Serve Solutions, it is supplied for research and development purposes.

Diarrhoea Management
Loperamide hydrochloride is a well-established active pharmaceutical ingredient for the symptomatic treatment of diarrhoea. It works by decreasing the flow of water and electrolytes into the bowel and by slowing down the movement of the bowel.
Gastrointestinal Motility Inhibition
This compound acts as a peripheral opioid receptor agonist, specifically targeting the myenteric plexus. This mechanism allows for the inhibition of gastrointestinal motility, which is crucial in managing conditions involving excessive bowel movements.
Research and Development
As a bioactive small molecule and approved therapeutic, Loperamide hydrochloride is valuable for pharmacological research. It is used in studies investigating opioid receptor pathways, ion channel modulation, and gastrointestinal physiology.
