Work Mechanism & Pharmacology
Patient Overview of Work Mechanism
Albuterol relaxes the tight muscular bands surrounding constricted airways in your lungs, opening air passages within minutes to restore easy breathing during asthma or COPD flare-ups.
Clinical Mechanism of Action (MoA)
Selective short-acting beta-2 adrenergic receptor agonist (SABA). Stimulates beta-2 receptors on bronchial smooth muscle, activating intracellular adenylate cyclase and increasing cyclic 3',5'-adenosine monophosphate (cAMP). Elevated cAMP activates protein kinase A (PKA), inhibiting myosin light-chain phosphorylation and inducing rapid bronchodilation.
