Isopropamide iodide is an anticholinergic agent used to reduce saliva and gastrointestinal secretions. It is commonly prescribed for patients requiring control of excessive salivation or in combination with other treatments for digestive system disorders, such as intestinal spasms or hyperacidity in peptic ulcers. It acts by inhibiting the neurotransmitter acetylcholine, thereby decreasing smooth muscle motility in the gastrointestinal tract and reducing secretions from various glands.
