Description
Curator's Comment: description was created based on several sources, including ISBN-13: 978-0323055932

Diphenoxylate is an opioid drug used for the treatment of acute diarrhea. The drug is used in combination with atropine and marketed under names Lomotil and Diphenoxylate hydrochloride and atropine sulfate. Diphenoxylate is biotransformed in man by ester hydrolysis to diphenoxylic acid (difenoxine), which is biologically active and the major metabolite in the blood. The drug exerts its action by activating mu opioid receptors of intestinal mucosa.

CNS Activity

Curator's Comment: At high doses it exhibits codeine-like subjective effects.
