🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two active ingredients with complementary actions. Bromhexine is a mucolytic that reduces the viscosity of mucus by breaking down acidic mucopolysaccharide fibers, making secretions thinner and easier to expectorate. Guaifenesin is an expectorant that increases the volume and reduces the viscosity of respiratory tract secretions by increasing hydration of mucus, thereby facilitating its removal by ciliary action and coughing. Together, they enhance mucociliary clearance and provide symptomatic relief from productive cough.
