Clidinium is used to treat peptic ulcers, irritable bowel syndrome, functional GI disorders, and other conditions involving excessive stomach acid or intestinal spasms.
As an anticholinergic, clidinium blocks acetylcholine receptors in the GI tract, reducing gastric secretions, decreasing GI motility, and relieving smooth muscle spasms.
May cause dry mouth, constipation, blurred vision, and urinary retention. Should be used cautiously in elderly patients and those with glaucoma, BPH, or urinary obstruction. Avoid in hot environments as it impairs sweating. Often combined with benzodiazepines for ulcer treatment.
