S-Carboxymethyl-L-cysteine/ Carbocisteine is a respiratory mucolytic agent. Its action is similar to that of bromhexine in that it causes the disulfide bond of mucin in sputum to be cleaved, thereby reducing the viscosity of sputum and increasing the mucus fibres in sputum, lubricating the bronchial lining, increasing the secretion of low viscosity salivary mucin and reducing the production of high viscosity rockweed mucin, thereby reducing the viscosity of sputum and making it easier to cough up.

Function

Function and Application of  S-Carboxymethyl-L-cysteine/ Carbocisteine CAS 2387-59-9
1. S-Carboxymethyl-L-cysteine/ Carbocisteine is a respiratory mucolytic agent. Its action is similar to that of bromhexine in that it causes the disulfide bond of mucin in sputum to be cleaved, thereby reducing the viscosity of sputum and increasing the mucus fibres in sputum, lubricating the bronchial lining, increasing the secretion of low viscosity salivary mucin and reducing the production of high viscosity rockweed mucin, thereby reducing the viscosity of sputum and making it easier to cough up.
2. S-Carboxymethyl-L-cysteine/ Carbocisteine Mainly used for the treatment of chronic bronchitis, bronchial asthma and other diseases that cause thick sputum, difficult coughing and sputum obstruction of the airways
