Storage method

This product is sealed and stored in a dry place away from light.

Synthesis method

Xanton-9-Carboxylic acid and diisopropylaminoethanol ester in xylene��, on137-140Dehydration reaction10h. After the reaction is completed, add activated carbon for decolorization and cool to 0, pressure filtration, and the filtrate is decompressed to recover xylene and excess Diisopropylaminoethanol, xanthene-9- Carboxylic acid-β-Diisopropylaminoethyl ester. Then react with methyl bromide to form a quaternary ammonium salt to prepare propantheline bromide.

Purpose

anticholinergic and antispasmodic, Has similar effects to atropine. It is suitable for gastric and duodenal ulcers, gastritis, pancreatitis, intestinal spasm, hyperhidrosis and pregnancy vomiting.
