What is Methscopolamine

Methscopolamine is an oral muscarinic-receptor antagonist structurally similar to scopolamine.

Historically, methscopolamine and other similar anticholinergics were often used, along with antacids, to decrease gastric acid secretion in patients with peptic ulcer disease.

More effective agents are currently available (H2-receptor blockers, proton-pump inhibitors) to manage peptic ulcer disease, including the use of antimicrobials and gastric acid suppression to eradicate Helicobacter pylori.

Although methscopolamine is FDA-approved as adjunctive therapy in the management of peptic ulcer disease, its efficacy in healing peptic ulcers, decreasing recurrence rate, or preventing complications has never been demonstrated.

Currently, methscopolamine has limited use in the treatment of peptic ulcer disease. Due to its anticholinergic effects on bronchial receptors, methscopolamine is also an ingredient in some combination products for the temporary relief of symptoms of allergic rhinitis, sinusitis, and the common cold.

Methscopolamine was approved by the FDA in 1952.

A lactose-free formulation of Pamine® was approved during June, 2001.
