DescriptionCarbocisteine is a mucolytic that reduces the viscosity of sputum to relieve the symptoms of chronic obstructive pulmonary disorder (COPD) and bronchiectasis through easier expulsion of mucus. Carbocisteine should not be used with antitussives (cough suppressants) or medicines that dry up bronchial secretions as they are functional antagonists. Carbocisteine is produced by alkylation of cysteine with chloroacetic acid.
