Salmeterol interacts with β2-adrenergic receptors found on the outer layer of airway smooth muscle cells. This interaction triggers the receptor′s activation, subsequently stimulating adenylyl cyclase, an enzyme that enhances the generation of cAMP. The increased levels of cAMP then initiate the activation of protein kinase A, resulting in the relaxation of airway smooth muscle cells and ultimately leading to bronchodilation.
