Mechanism of action

Albuterol activates beta-2 adrenergic receptors on bronchial smooth muscle, triggering a cascade that increases intracellular cAMP and leads to smooth muscle relaxation. This results in rapid airway dilation and improved airflow, providing symptomatic relief of bronchoconstriction. It is commonly used as a rescue medication for acute bronchospasm and as a maintenance therapy in obstructive airway diseases.
