Mechanism of action

Levalbuterol is the active R-enantiomer of albuterol that binds to beta-2 adrenergic receptors on airway smooth muscle cells, triggering increased intracellular cAMP and causing bronchodilation. This rapidly opens constricted airways and improves airflow in patients with obstructive airway diseases. As the pure active enantiomer, levalbuterol may provide enhanced efficacy with potentially fewer side effects compared to racemic albuterol.
