Mechanism of action

When inhaled as an aerosol, the 3% sodium chloride solution creates an osmotic gradient across the airway epithelium, drawing water into the mucus layer and increasing its hydration. This reduces mucus viscosity and improves mucociliary clearance, facilitating expectoration of secretions and improving airway patency. The mechanism is purely physical/osmotic rather than pharmacological.
