Cough expectorants & mucolytics

Carbocisteine reduces goblet cell hyperplasia and therefore plays a role in the management of disorders characterised by abnormal mucous. Carbocisteine loosens thick sputum effectively by reducing its viscosity and thereby helps to expectorate that mucus more easily from the respiratory tract. The mucolytic action happens in several mechanisms. It breaks the disulphide bonds, which cross-link certain glycoprotein molecules in the mucus, the mucus produced under the influence of Carbocisteine has high sialomucin and low fucomucin content. This combined effect ultimately reduces the viscosity of the sputum and increases its volume.
