Loperamide is the active ingredient of Adco-Loperamide, Betaperamide, Cipla Loperamide, Gastron, Imodium, Lopedium, Loperastat, Norimode and Prodium.

General information

Loperamide reduces gastrointestinal motility - the ability of the digestive tract to propel its contents. It is commonly used for the short-term management of mild to moderate diarrhoea. It should be used in combination with - and not as a substitute to - oral rehydration solutions to ensure adequate fluid and electrolyte intake.

If used to treat acute diarrhoea, loperamide treatment should be continued for 24-36 hours before it can be deemed ineffective. If this is the case and diarrhoea persists or worsens, the medication should be stopped and a doctor should be consulted.

How does loperamide work?

This medication increases the transit time of intestinal contents. This prolonged transit time leads to an increased absorption of fluid throughout the intestinal tract, thereby relieving diarrhoea.
