How does Broncorex Syrup Work?/Mechanism of action

Broncorex Syrup is a medicine that is used in treating the symptoms of Productive/wet cough. The Bromhexine in this syrup is a mucolytic. It works by depolymerizing mucopolysaccharides directly and by liberating lysosomal enzymes. This leads to the breaking of Mucus and makes it easier to cough out.

The Guaifenesin in this syrup is an Expectorant/Bronchial secretion enhancer. It works by stimulating the secretory glands and increase respiratory fluid production. This in result reduces the stickiness and decreases the viscosity of the mucus, which facilitates its removal by coughing.

While Terbutaline in this Syrup is a Bronchodilator. It works by stimulating the β2 receptors and increase cAMP formation in Bronchial muscle cells. This leads to the relaxation of muscles in the airways and makes breathing easier.

Together, These three medicines help in treating the wet/productive cough and make it easier to breathe.
