Pharmacology (Mechanism of Action)

Albuterol: Stimulates adenyl cyclase, increasing cAMP which relaxes bronchial, uterine, and vascular smooth muscle through β-2-adrenergic receptor stimulation.
Ipratropium: An anticholinergic that inhibits vagally mediated reflexes and prevents acetylcholine from increasing cyclic-GMP in bronchial smooth muscle. Also exhibits anti-secretory properties.
