Methscopolamine, usually provided as a bromide salt (Pamine), is an oral medication used along with other medications to treat peptic ulcers by reducing stomach acid secretion. With the advent of proton pump inhibitors and antihistamine medications it is rarely used for this anymore. It can also be used for stomach or intestinal spasms, to reduce salivation, and to treat motion sickness. Methscopolamine is also commonly used as a drying agent, to dry up post-nasal drip, in cold,irritable bowel syndrome and allergy medications (Extendryl, AlleRx, Rescon).

Methscopolamine, a methylated derivative of scopolamine, is a muscarinic antagonist structurally similar to the neurotransmitter acetylcholine. Its mechanism of action involves blocking the muscarinic acetylcholine receptors.
