Lower Gastrointestinal Tract Motility Regulator
Action And Clinical Pharmacology: Trimebutine is a noncompetitive spasmolytic agent. It possesses moderate opiate receptor affinity and has a marked antiserotonin activity especially on “mu” receptors. It induces regulation of spontaneous activity and increases synchronization between electrophysiological spikes and contractions in isolated guinea pig taenia coli and ileum. However, it does not alter normal motility, but regulates abnormal intestinal activity. tag_IndicationsIndications
