🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two active ingredients with complementary actions on mucus. Bromhexine is a mucolytic that reduces the viscosity of mucus by breaking down acidic mucopolysaccharide fibers, making secretions thinner and easier to expel. Guaifenesin is an expectorant that increases the volume and reduces the viscosity of bronchial secretions by drawing water into the mucus, which helps the cilia move mucus more effectively. Together, they improve the productivity of cough and help clear airways.
