Otilonium bromide, sold under the trade name Spasmomen among others, is an antimuscarinic and calcium channel blocker used to relieve spasmodic pain of the gut, especially in irritable bowel syndrome.^[1] This means it works in the gut themselves, by relaxing the small muscles of the intestines, which results in relieving cramps and therefore reduces pain.
