General description

Clidinium bromide is an anticholinergic, antisecretory and antispasmodic drug, widely used in treating anxiety-related conditions and spastic colon by inhibiting the action of parasympathetic innervations thus decreasing the secretions of stomach acid and slowing the intestines.

Application

Clidinium bromide has been used as an analytical standard for the quantification of the analyte in pharmaceutical formulations using different analytical techniques.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
