Description

 

Acetylcysteine is the acetylated form of L-cysteine.It is a pharmaceutical drug and nutritional supplement used primarily as a mucolytic agent and in the management of paracetamol (acetaminophen) overdose.It is used as a cough medicine because it breaks disulfide bonds in mucus and liquefies it, making it easier to cough up. It is also this action of breaking disulfide bonds that makes it useful in thinning the abnormally thick mucus in Cystic Fibrosis patients.It is very efficiently absorbed and has been shown to protect cells directly and support the immune system. Acetylcysteine is an antioxidant and a free radical-scavenging agent that increases intracellular glutathione at the cellular level.It can act as a precursor for glutathione synthesis as well as a stimulator of the cytosolic enzymes involved in glutathione regeneration.It is used in medical treatment of chronic bronchitis, cancer, and paracetamol intoxication.
