Isopropamide iodide is a medication that belongs to the class of drugs known as anticholinergics. It is primarily used as an antispasmodic agent to treat various gastrointestinal conditions, particularly those involving smooth muscle spasms.Isopropamide iodide works by blocking the action of acetylcholine, a neurotransmitter that plays a role in muscle contraction. By inhibiting acetylcholine, isopropamide iodide helps to relax the smooth muscles in the gastrointestinal tract, relieving spasms and reducing associated symptoms such as abdominal pain, cramping, and bowel disturbances.
