Mechanism of action

Hypertonic saline works by creating an osmotic gradient that draws fluid into the airway lumen, hydrating secretions and improving mucociliary clearance. Epinephrine acts as an alpha-1 and beta-2 adrenergic agonist, causing vasoconstriction to reduce submucosal edema and stimulating beta-2 receptors to promote bronchodilation. Together, these agents reduce airway obstruction and improve ventilation, particularly in acute bronchiolitis and croup.
