Oxyphenonium bromide Usage And Synthesis

Originator

A-Spasm ,Acme Laboratories Ltd.

Uses

anticholinergic, anticonvulsant

Manufacturing Process

1 mol cycloxehylhydroxyphenylacetic acid methyl ester was mixed with 1 mol 2-diethylaminoethanol in presence of 1 mol sodium methylate to give cycloxehylhydroxyphenylacetic acid 2-diethylamino-ethyl ester.
5 parts by weight of it was dissolved in 50 volumes glacial acetic acid and a gaseous methyl bromide was introduced. The mixture was heated to about 50°C and crystallization of cycloxehylhydroxyphenylacetic acid diethylaminoethyl ester methyl bromide has shortly after begun. On cooling the crystals was filtered off and recrystallized from mixture of ethyl acetate ant a little ethanol to give the oxyphenonium bromide. MP: 189°-191°C.

brand name

Antrenyl (Novartis).

Therapeutic Function

Anticholinergic, Spasmolytic

Safety Profile

Poison by ingestion, intramuscular, intraperitoneal, intravenous, and subcutaneous routes. Human systemic effects by ingestion: change in heart rate. When heated to decomposition it emits very toxic fumes of NOx, NH3, and Brí.
