🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two mucoactive agents. Acetylcysteine is a mucolytic that breaks disulfide bonds in mucoproteins, reducing mucus viscosity. Ambroxol is a mucokinetic agent that increases serous bronchial secretion, enhances ciliary motility, and stimulates surfactant production. Together, they improve mucus clearance from the respiratory tract.
