N-acetylcysteine (NAC) is a sulfur-containing amino acid that is produced naturally by the body. It helps prevent cell deterioration and may improve breathing for individuals with lung issues. NAC plays a role in boosting the synthesis of glutathione, a powerful antioxidant. When ingested, NAC is rapidly converted into the essential amino acid cysteine during first-pass metabolism, after which it is stored in the liver and released into the bloodstream.NAC is commonly prescribed to treat various medical conditions and is also used as a nutritional supplement. It helps break down mucus in people with respiratory conditions such as cystic fibrosis, chronic bronchitis, and asthma. Furthermore, it is beneficial in treating liver disease, increasing insulin sensitivity, and alleviating symptoms of psychiatric disorders like bipolar disorder and obsessive-compulsive disorder.The respiratory care devices market is experiencing significant growth, driven by a concerning rise in chronic respiratory diseases such as COPD and asthma, as well as an increasingly aging global population.
