Mechanism of action

Albuterol activates beta-2 adrenergic receptors on bronchial smooth muscle cells, triggering a cascade that increases intracellular cAMP levels. This leads to smooth muscle relaxation and rapid airway dilation, relieving bronchoconstriction. The HFA (hydrofluoroalkane) formulation is a propellant system used in metered-dose inhalers (MDI) for pulmonary delivery.
