🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two active ingredients with complementary actions. Guaifenesin is an expectorant that works by increasing the volume and reducing the viscosity of mucus in the respiratory tract. It does this by drawing water into the mucus, making it thinner and easier to cough up. Bromhexine is a mucolytic that works by breaking down the chemical bonds in mucus, further reducing its thickness and stickiness. Together, they help clear the airways of thick, tenacious mucus, providing symptomatic relief from a productive cough. They do not suppress the cough reflex and are not intended to treat the underlying cause of the cough.
