Mechanism of action

Albuterol is a short-acting beta-2 agonist that increases cAMP in airway smooth muscle cells, causing bronchodilation. Ipratropium bromide is an anticholinergic agent that blocks M3 muscarinic receptors on airway smooth muscle, preventing acetylcholine-induced bronchoconstriction. Together, they provide complementary bronchodilation through independent pathways, making the combination more effective than either agent alone for acute airway obstruction.
