Also Known As: Glycopyrrolate, Robinul
Glycopyrrolate is a medication of the muscarinic anticholinergic group. It does not cross the blood brain barrier and consequently has no to few central effects. It is a synthetic quaternary amine. It is available in oral and intravenous (i.v.) forms.
In anesthesia, glycopyrrolate injection can be used as a preoperative medication in order to reduce salivary, tracheobronchial, and pharyngeal secretions, as well as decreasing the acidity of gastric secretion. It is also used in conjunction with neostigmine, a neuromuscular blocking reversal agent, to prevent neostigmine's muscarinic effects such as bradycardia.
With counterion, it is known as glycopyrronium bromide.
