Uses:
Biological reagents, bulk drugs, the sulfhydryl group (-SH) contained in the molecule can break the disulfide chain (-S-S) that connects the mucin peptide chain in mucus sputum. Mucin becomes a peptide chain of small molecules, which reduces the viscosity of sputum; it can also break DNA fibers in purulent sputum, so it can not only dissolve white viscous sputum but also purulent sputum. It is used in biochemical research, as a phlegm solubilizer and an antidote for acetaminophen poisoning in medicine. The mechanism of action is that the sulfhydryl group contained in the product’s molecular structure can break the disulfide bond in the mucin polypeptide chain in mucinous 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 a large number of sticky sputum blockages that cause severe symptoms due to difficulty in sucking.
