Dicyclomine is a medicine used to treat irritable bowel syndrome, which belongs to a class of drugs called anticholinergics. The mechanism of action of anticholinergics is to block the action of acetylcholine. Thereby, thanks to a group of anticholinergic drugs that have a direct relaxing effect on the muscles, Dicyclomine is used to reduce the contraction of the muscles in the intestine, improving the discomfort for patients with irritable bowel syndrome.
