Trimebutine is a drug with antimu-receptor)scarinic and very weak mu opioid agonist effects. It is used for the treatment of irritable bowel syndrome and other gastrointestinal disorders. The major product from drug metabolism of trimebutine in human beings is nortrimebutine, which comes from removal of one of the methyl groups attached to the nitrogen atom. Trimebutine exerts its effects in part due to causing a premature activation of phase III of the migrating motor complex in the digestive tract. Both trimebutine and its metabolite are commercially available.
