Description
Sources: https://www.drugs.com/pro/methscopolamine.html

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.

Conditions

Condition	Modality	Highest Phase	Product
Peptic ulcer 72 Sources: https://www.drugs.com/pro/methscopolamine.html	Primary	Approved 8429	PAMINE Approved Use Methscopolamine bromide is an anticholinergic agent which possesses most of the pharmacological actions of that drug class. These include reduction in volume and total acid content of gastric secretion, inhibition of gastrointestinal motility, inhibition of salivary excretion, dilation of the pupil and inhibition of accommodation with resulting blurring of vision. Large doses may result in tachycardia. Launch Date -5.27990391E11
Allergy 44 Sources: https://www.drugs.com/pro/dallergy-chewable-tablets.html	Palliative	Approved 8429	DALLERGY Approved Use This product provides relief of the symptoms resulting from irritation of sinus, nasal, and upper respiratory tract tissue. Phenylephrine exerts a vasoconstrictive and decongestive action while chlorpheniramine maleate decreases the symptoms of watering eyes, post nasal drip, and sneezing. Methscopolamine nitrate further augments the antisecretory activity of this product.

Sample Use Guides

In Vivo Use Guide

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 Vitro Use Guide

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.
