Isopropamide iodide（Cat No.:R044777）is a quaternary ammonium anticholinergic agent that acts as a long-acting muscarinic receptor antagonist. It reduces gastrointestinal motility and gastric acid secretion by blocking parasympathetic activity, making it useful for studying disorders such as peptic ulcer, irritable bowel syndrome, and intestinal spasms. Due to its quaternary structure, it has poor penetration across the blood–brain barrier, which minimizes central nervous system effects compared to tertiary amines. Supplied as the iodide salt, it provides stability and solubility, serving as a reliable reference in gastrointestinal pharmacology research.
