Mechanism of action

Salmeterol activates beta-2 adrenergic receptors on bronchial smooth muscle cells, triggering a cascade that increases intracellular cAMP levels, leading to smooth muscle relaxation and sustained bronchodilation. The Diskus is a dry powder inhaler formulation that delivers salmeterol directly to the lungs for local action. It is used as a maintenance therapy for chronic airway obstruction, typically in combination with inhaled corticosteroids.
