Carbocisteine is a mucolytic that reduces the viscosity of sputum and
so can be used to help relieve the symptoms of chronic obstructive pulmonary disorder (COPD)
and bronchiectasis by allowing the sufferer to bring up sputum more easily.
Carbocisteine should not be used with antitussives (cough suppressants) or medicines that dry up bronchial secretions.
Carbocisteine is produced by alkylation of cysteine with chloroacetic acid.
