Investigation of glycopyrrolate as a premedicant drug.

The clinical efficacy of glycopyrrolate, a synthetic anticholinergic drug, for premedication was compared in a double-blind study with that of atropine or hyoscine in patients anaesthetized with diethyl ether. The antisialogogue actions of the three drugs were similar. Glycopyrrolate produced less tachycardia, pyrexia and blurred vision than atropine, and its sedative effect was less than that of hyoscine.
