Mechanism of action

N-acetylcysteine works by breaking disulfide bonds in mucoproteins, thereby reducing mucus thickness and improving clearance. Sodium bicarbonate raises pH to create a less acidic environment that may further facilitate mucus mobilization and reduce airway irritation. This combination is used to improve airway clearance in conditions characterized by thick, tenacious secretions.
