N-Acetyl Cysteine (NAC) And The Liver
N-Acetyl Cysteine or NAC is an antidote for poisonous effects of paracetamol overdose. It targets the cells in the liver, raising their capacity to deal with harmful metabolites. There are a number of researches well underway that scrutinizes a variety of medical conditions for which this compound could be of use. It is a known precursor of antioxidants and in itself a scavenger of peroxides and free radicals.
Hepatocytes are the cells that take on most of the functions of the liver and account for more than 70 per cent of the liver’s total mass. These cells are responsible for the presystematic metabolism of drugs, also known as the first-pass effect, rendering most drugs innocuous before they are released into the bloodstream. The total amounts of bioactive substances that are distributed to the rest of the body are also largely regulated by hepatocytes, notably carbohydrates. In addition, they are involved in the biosynthesis of protein, cholesterol, phospholipids, and bile salts as well as the functional reserves for protein.
Hepatocytes and Toxins
Certain drugs produce toxins when broken down by hepatocytes. A classic example is the metabolism of ethanol into acetaldehyde, which is a toxic compound, a probable carcinogen, and an air pollutant emitted by combustion of cars and tobacco smoking. While hepatocytes are known for their detoxifying responses to toxic substances entering the body, the metabolism of toxins actually takes up a great deal of time, resulting in certain toxins getting released into the bloodstream prior to first-pass effect.
That being said, continued exposure to toxins wears down hepatocytes, and high concentrations of what we refer to as poisons is certain to bring damage to the liver. This is what happens during overdose of paracetamol, or acetaminophen. In an effort to metabolized excessive amounts of the drug, the liver cells produce by-products that are essentially poisons, which under normal circumstances can be contained well.
NAC and Glutathione Production
The major antioxidant synthesized by the human body called glutathione comes to the liver’s defense when toxic by-products are produced. Hepatocytes in particular are so dependent on glutathione in the quenching of toxins that it has been observed that any challenge to the manufacture of this endogenous antioxidant will ultimately result in liver failure.
Glutathione is released by hepatocytes in large amounts especially during the metabolism of alcohol and drugs, but during overdose the ravaging activities of ethanol or drug metabolites overwhelm the detoxifying effects of antioxidant reserves in the body. Simply put, the defense mechanisms in the employ of the body have limits. NAC resolves this problem.
The presence of NAC in the body augments the liver’s ability to produce the needed amounts of glutathione to effectively counter the harmful properties of invasive substances. In fact, the liver completely recuperates in a matter of weeks even after life-threatening conditions given that NAC is introduced in the human body in time to avoid subsequent damages to other vital organs. Indeed its application has proven to save lives in fatal cases of paracetamol poisoning.
N-Acetyl Cysteine is available at your local or internet vitamin store in capsule or tablet forms. Always choose name brands like Source Naturals to ensure quality and purity of the product you buy for better liver health.
