Description

A muscarinic antagonist structurally related to atropine but often considered safer and more effective for inhalation use. It is used for various bronchial disorders, in rhinitis, and as an antiarrhythmic.

Indication

For maintenance treatment of bronchospasm associated with chronic obstructive pulmonary disease, including chronic bronchitis and emphysema.

Mechanism of Action

Ipratropium bromide is an anticholinergic agent. It blocks muscarinic cholinergic receptors, without specificity for subtypes, resulting in a decrease in the formation of cyclic guanosine monophosphate (cGMP). Most likely due to actions of cGMP on intracellular calcium, this results in decreased contractility of smooth muscle.

Pharmacokinetics

Absorption
Inhalation (local)-minimal; Nasal-rapid and minimal
Distribution
* 4.6 L/kg
Metabolism
Partially metabolized to at least 8 metabolites formed primarily via hydrolysis and conjugation. The main metabolites are N-isopropylnortropium methobromide, which is formed by enzymatic hydrolysis of the ester; α-phenylacrylic acid-N-isopropylnortropine-ester methobromide, which is formed by enzymatic loss of a water; and phenylacetic acid-N-isopropylnortropine-ester methobromide, which is formed by enzymatic loss of a CH3OH-group. These metabolites appear to be inactive.
Elimination

Clearance

* 2.3 L/min (total clearance of active ingredient)
