Nacetilcistein

N-acetylcysteine, often abbreviated as NAC, is a derivative of the amino acid cysteine. It is a supplement that has been used for a variety of medical purposes. NAC functions as an antioxidant and a precursor to glutathione, a crucial antioxidant in the body. Glutathione plays a role in protecting cells from oxidative damage.

Medically, NAC is recognized for its mucolytic properties, meaning it can break down mucus. This makes it useful in the treatment of respiratory conditions such as chronic bronchitis, cystic fibrosis, and emphysema, where thick mucus can obstruct airways. It is administered in various forms, including inhalations and oral supplements.

Beyond its respiratory applications, NAC has been explored for its potential in treating acetaminophen (paracetamol) overdose. In this scenario, it helps to replenish glutathione levels in the liver, which are depleted by the toxic metabolite of acetaminophen, thereby preventing liver damage. Research has also investigated NAC's role in mental health conditions, although its efficacy in these areas is still under investigation. It is generally considered safe, but potential side effects can include nausea, vomiting, and diarrhea. Individuals considering NAC should consult a healthcare professional for appropriate dosage and guidance.
