Trimebutine Maleate

Indications

Treatment and relief of symptoms associated with irritable bowel syndrome (spastic colon). Postoperative paralytic ileus in order to accelerate the resumption of the intestinal transit following abdominal surgery.

Pharmacology

Trimebutine maleate is a noncompetitive spasmolytic agent. It possesses moderate opiate receptor affinity and has marked anti-serotonin activity especially on 'mu' receptors. It induces regulation of spontaneous activity and increases synchronization between electrophysiological spikes and contractions in isolated guinea pig strips of colon and ileum. However, it does not alter normal motility, but regulates abnormal intestinal activity.

Dosage & Administration

For adults: 100 mg to 200 mg, 3 times per day before meals.

Interaction

Trimebutine maleate increases the duration of d-tubocurarine-induced curarization. No other druginteractions have been observed during clinical trial or otherwise reported.
