🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two active ingredients with complementary actions. Terbutaline selectively stimulates beta-2 adrenergic receptors on bronchial smooth muscle, which increases intracellular cyclic AMP and leads to relaxation of the airways, thereby relieving bronchospasm. Bromhexine works on the respiratory tract secretions by breaking down acidic mucopolysaccharide fibers in mucus, reducing its viscosity and making it easier to cough out. The combined effect is bronchodilation plus improved mucus clearance, which helps relieve cough and congestion.
