Products Description
What is N-acetyl-L-cysteine?
N-acetyl-L-cysteine is a biochemical reagent and medicine. It is used as an expectorant and is said to be easy to clear phlegm and easy to cough. It has a decomposing effect on thick sputum. The mechanism of action is that the sulfhydryl group contained in the molecular structure of this product can break the disulfide bonds in the mucin polypeptide chain in the sputum, decompose the mucin, reduce the viscosity of the sputum, and make it liquefied and easy to cough up. It is suitable for patients with acute and chronic respiratory diseases whose sputum is thick and difficult to cough up, as well as critical symptoms of difficulty in breathing caused by a large amount of sticky sputum blocking the air.
