Property

CAS No.: 638-23-3 Formula: C5H9NO4S Molecular Weight: 179.19400

Description

Carbocisteine (INN), also called carbocysteine (USAN), 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.
