Where is S-Carboxymethyl-L-cysteine powder usually used?
S-Carboxymethyl-L-cysteine powder is mainly used for patients with thick sputum and difficulty in coughing up phlegm caused by chronic bronchitis, bronchial asthma and other diseases. In addition, it is also used to treat phlegm viscosity and difficulty in expectoration caused by diseases such as emphysema and chronic obstructive pulmonary disease (COPD). This drug affects the secretion of bronchial glands, reduces sputum viscosity, increases mucosal ciliary clearance rate, and reduces airway hyperresponsiveness. In clinical application, its combination with Xiaochaihu granules has a good therapeutic effect on chronic bronchitis. However, it should be noted that this medication has a stimulating effect on the digestive tract and can cause adverse reactions such as stomach discomfort, nausea, vomiting, gastrointestinal bleeding, etc. Patients with active digestive ulcers should not use it.
What are the effects of S-Carboxymethyl-L-cysteine powder?
The effect of S-Carboxymethyl-L-cysteine powder is as follows:
Expelling phlegm and improving respiration: It can affect the secretion of bronchial glands, increase the secretion of low viscosity salivary mucin, reduce the production of high viscosity fucoidan, and directly act on the disulfide bonds of mucin, causing the breakdown of mucin molecules and reducing the viscosity of sputum, making it easier to cough up phlegm.
Antioxidant: After entering the body, it is easy to remove carboxymethyl groups to form cysteine. The thiol groups contained in cysteine can interact with electrophilic groups such as reactive oxygen species, exerting direct antioxidant effects. Moreover, cysteine is also a precursor of glutathione (GSH), which can synthesize biologically active GSH and increase the concentration of GSH in the body, playing an indirect antioxidant role.
Reduce airway hyperresponsiveness: This substance can also increase mucosal ciliary clearance rate, reduce airway hyperresponsiveness, and to some extent improve the state of the airway for patients with respiratory diseases, reducing discomfort caused by external stimuli.
Preventing deafness: It can also be used for non suppurative otitis media in children and has a certain preventive effect on deafness
Reducing myocardial injury: Studies have revealed that it can significantly alleviate cyclophosphamide induced myocardial injury by inhibiting oxidative stress and the NF - κ B/NLRP3 inflammasome axis, while activating the Nrf2/HO-1 pathway
