used to treat the symptoms of irritable bowel syndrome (IBS). Mebeverine is a musculotropic antispasmodic, with a direct action on the smooth muscle of the gastrointestinal tract, relieving spasm without affecting normal gut motility. Since this action is not mediated by the autonomic nervous system, the usual anticholinergic side effects may be absent. Mebeverine is suitable for patients with prostatic hypertrophy and glaucoma.
