Action
Description: Glycopyrronium bromide is a quarternary ammonium antimuscarinic. It blocks acetylcholine at parasympathomimetic sites and induces smooth muscle relaxation. It also reduces gastric acid secretions and controls pharyngeal, tracheal and bronchial secretions. It antagonises muscarinic symptoms such as bronchorrhoea, bronchospasm, bradycardia and intestinal hypermotility induced by anticholinesterases.
Onset: 15-30 minutes (IM), 1 minutes (IV).
Duration: 2-3 hr (vagal blocking effect), 7 hr (sialogogue effects).
Pharmacokinetics:
Absorption: Poorly absorbed from the GI tract (oral); about 10-25% is absorbed after an oral dose.
Distribution: Blood-brain barrier (poor penetration).
Excretion: Via bile and urine.
Storage
Store at 20-25°C.
