  • Applications

    Methscopolamine bromide is primarily used as an antispasmodic and anti-secretory active pharmaceutical ingredient in prescription medicines for gastrointestinal indications. It is formulated in oral dosage forms to reduce gastric and intestinal motility and secretions associated with peptic ulcers and irritable bowel syndrome, and is sometimes included in combination therapies with acid-suppressing agents. In research and development, it may be used as a pharmacology tool to study muscarinic receptor activity and cholinergic signaling. Its use is subject to local regulations and formulation limits.
