Description: Clidinium bromide (Ro 2-3773) , a synthetic anticholinergic agent, has been shown in experimental and clinical researchers to have a pronounced antisecretory and antispasmodic effect on the gastrointestinal tract. It can inhibit muscarinic actions of acetylcholine at postganglionic parasympathetic...

Clidinium is a gastrointestinal muscarinic receptor antagonist (Ki = 3 nM against [3H]quinuclidinyl benzilate binding in rat colonic enterocytes). Administration of clidinium, at a dose of 1 mg/kg, slows intestinal transit and induces constipation in mice. This clidinium-induced constipation induces serum...
