Mode of Action
How Does It Work?
Glycopyrrolate blocks the muscarinic acetylcholine receptor. It prevents the action of acetylcholine on the structures innervated by postganglionic cholinergic nerves and smooth muscles. Which, in return, reduces the salivary, tracheobronchial, and pharyngeal secretions. It also decreases the acidity of gastric secretions, blocks cardiac vagal inhibitory reflexes during intubation.
