🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two active ingredients with complementary actions. Terbutaline is a selective beta-2 adrenergic receptor agonist that works by stimulating beta-2 receptors in the smooth muscles of the airways, leading to relaxation and bronchodilation. Ambroxol is a mucolytic agent that reduces the viscosity of mucus by breaking down acidic mucopolysaccharide fibers and stimulating the production of surfactant, which helps to thin secretions and improve mucus clearance. Together, they help to open the airways and make it easier to cough out mucus.
