Mechanism of action

Ambroxol is a mucolytic agent. It inhibits the NO dependent activation of soluble guanylate cyclase which can suppress excessive mucus secretion. It also suppresses phlegm viscosity and improves the mucocilary transport of bronchial secretions.

Terbutaline causes stimulation of beta-adrenergic receptors of adenyl-cyclase. It catalyses the conversion of ATP to c-AMP and c AMP levels are associated with relaxation of bronchial smooth muscle.

Guaiphenesin reduces the viscosity of secretion and act as an expectorant in trachea and bronchi. It aids the flow of respiratory tract secretion, loosened the mucus secretion.
