Sample Use Guides

In Vivo Use Guide

Diphenylmethane methylsulfate was prescribed for the treatment of hyperhidrosis in a divided daily dosage of 200—400 mg. Fifteen patients with severe gustatory sweating after total parotidectomy and facial nerve preservation were alternatively treated with topically applied placebo and topically applied 2% diphemanil methylsulfate. 2 mg dose of diphemanil, administered by oral inhalation 20 minutes before histamine challenge, is ineffective in protecting against induced bronchospasm in asymptomatic adult asthmatics.
