Mechanism of action

Salmeterol xinafoate binds to beta-2 adrenergic receptors on airway smooth muscle, causing bronchodilation with a duration of action of 12 hours. Fluticasone propionate acts as a glucocorticoid receptor agonist in the lungs, suppressing inflammatory responses including cytokine production and immune cell recruitment. Together, they provide both acute bronchodilation and chronic anti-inflammatory effects for asthma and COPD management.
