Methscopolamine bromide is an anticholinergic agent used along with other medications to treat peptic ulcers by reducing stomach acid secretion. Methscopolamine is also commonly used as a drying agent, to dry up post-nasal drip, in cold, irritable bowel syndrome and allergy medications. Methscopolamine binds to M1-M5 isoforms of muscarinic receptors.

Sample Use Guides
The average dosage of Methscopolamine Bromide Tablets USP is 2.5 mg one-half hour before meals and 2.5 to 5 mg at bedtime. A starting dose of 12.5 mg daily will be clinically effective in most patients without the production of appreciable side effects.
Route of Administration:
Oral
In the standard assay, mAChR subtypes (20-30 fmol/tube) in particulate fractions of Sf9 cells were incubated with 4 to 4.2 nM [3H]NMS (methscopolamine) and different concentrations of muscarinic ligands in 20 mM K-phosphate buffer (pH 7). Bound [3H]NMS trapped on the filter was counted with a liquid scintillation counter.
