Pharmacology: Dicycloverine hydrochloride is an antimuscarinic agent with effects similar to but much weaker than those of atropine. It also has a direct antispasmodic action on smooth muscles and reduces secretions, especially salivary and bronchial secretions. It also reduces perspiration, but has a little effect on biliary or pancreatic secretion. Dicycloverine hydrochloride is used in the gastrointestinal spasm, particularly that associated with the irritable bowel syndrome and is also given in association with antacids as adjunct in the treatment of peptic ulcer.
