Glycopyrrolate Safety Profile

Poison by intravenous and intraperitoneal routes. Moderately toxic by ingestion and subcutaneous routes. Experimental reproductive effects. When heated to decomposition it emits very toxic fumes of NOx and Br. See also BROMIDES.

Glycopyrrolate Specification

  Glycopyrrolate , with CAS number of 596-51-0, can be called 1,1-dimethyl-3-hydroxypyrrolidiniumbromidealpha-cyclopentylmandelate ; 1-methyl-3-pyrrolidylalpha-phenylcyclopentaneglycolatemethobromide ; ahr504;asecryl;gastrodyn ; glycopyrrolatebromide ; nodapton ; pyrrolidinium,1,1-dimethyl-3-hydroxy-, bromide, alpha-cyclopentylmandelate . Glycopyrrolate (CAS NO.596-51-0) has some side effects as a medicine such as fever, heat stroke in hot environments, dry mouth, difficulty urinating, headaches, diarrhea and constipation. Glycopyrrolate (CAS NO.596-51-0) is a medicine used for treating stomach ulcers, asthma, COPD and hyperhidrosis. It is also used to reduce excessive saliva. In anesthesia, glycopyrrolate injection can be used as a preoperative medication to reduce salivary, tracheobronchial, and pharyngeal secretions, as well as decreasing the acidity of gastric secretion. It is also used to prevent neostigmine's muscarinic effects in combination with neostigmine.
