Oxyphenonium is an anticholinergic drug, a medication that reduces the effect of acetylcholine, a chemical released from nerves that stimulates muscles, by blocking the receptors for acetylcholine on smooth muscle (a type of muscle). It also has a direct relaxing effect on smooth muscle. Oxyphenonium is used to treat or prevent spasm in the muscles of the gastrointestinal tract in the irritable bowel syndrome. In addition, Oxyphenonium inhibits gastrointestinal propulsive motility and decreases gastric acid secretion and controls excessive pharyngeal, tracheal and bronchial secretions.
Reduced gastric motility interferes with absorption of other drugs. Effects potentiated by other antimuscarinics including amantadine, some antihistamines, phenothiazines and TCA.
Common side effects are dryness of mouth, headache, palpitations, etc.
Treatment is the same as for atropine overdosage.
