Dicyclomine hydrochloride is a medication classified as an anticholinergic and antispasmodic. It is primarily used to treat gastrointestinal conditions characterized by smooth muscle spasms, such as irritable bowel syndrome (IBS) and functional bowel disorders.Dicyclomine hydrochloride works by relaxing the smooth muscles of the gastrointestinal tract, including the stomach and intestines. It accomplishes this by blocking the action of acetylcholine, a neurotransmitter involved in muscle contraction. By inhibiting acetylcholine, dicyclomine helps relieve muscle spasms, cramps, and associated abdominal pain.
