What is Acetylcysteine?
Acetylcysteine is an organic compound having the chemical formula C5H9NO3S. It is sometimes known as N-acetylcysteine, but they are slightly different according to the application. It is a medication used to treat paracetamol overdose and to loosen thick mucus in individuals having chronic bronchopulmonary disorders such as pneumonia and bronchitis. Moreover, this medication has been used in treating lactobezoar in infants. We can take this medication intravenously, orally, or through inhalation as a mist. Sometimes, people use it as a dietary supplement as well.
There are some common side effects associated with this medication, such as nausea, vomiting, skin redness and itchiness, etc. However, it is apparently safe to be used during pregnancy.
If we are using this medication to treat paracetamol overdose, it can work by increasing the level of glutathione, which is an antioxidant that neutralizes the toxic breakdown products of paracetamol. Moreover, if we inhale it, it can act as a mucolytic by decreasing the thickness of mucus.
When taken by mouth, the bioavailability of acetylcysteine is about 10%. The protein binding ability ranges from 50 to 83%. The metabolism occurs in the liver. The elimination half-life is about 5.6 hours. Excretion of this medication occurs through the renal route or faecal route.
What is N-acetylcysteine?
N-acetylcysteine is a form of acetylcysteine, and it is banned from being used in supplements. This is because there is no evidence that this substance was used in supplements before its use as a drug, which leads to the unpopularity of the product, and it is illegal to be used as a supplement now.
Moreover, as a prescription drug, this medication is used by doctors to treat acetaminophen overdose, and it can also help break up mucus in people having some lung diseases.
What are the Similarities Between Acetylcysteine and N-acetylcysteine?
