PHARMACOLOGICAL PROPERTIES
Pharmacotherapeutic group: Anticholinergics
ATC Code : R03BB01
Mode of action
ATROVENT
®
(ipratropium bromide) is a quaternary ammonium compound with
anticholinergic (parasympatholytic)
properties. In non-clinical studies, it appears to inhibit vagally
mediated reflexes by antagonizing the action of
acetylcholine, the transmitter agent released from the vagus nerve.
Anticholinergics prevent the increase in intracellular
concentration of Ca++ which is caused by interaction of acetylcholine
with the muscarinic receptor on bronchial smooth
muscle.
Ca++ release is mediated by the second messenger system consisting of
IP3 (inositol triphosphate) and DAG
(diacylglycerol).
The bronchodilation following inhalation of ATROVENT
®
(ipratropium bromide) is primarily local and site specific to
the lung and not systemic in nature.
Non-clinical and clinical evidence suggest no deleterious effect of
