🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by breaking the disulfide bonds in mucus glycoproteins, which reduces the viscosity and elasticity of mucus. This makes it easier to clear from the respiratory tract. Additionally, acetylcysteine acts as a precursor to glutathione, a major antioxidant that protects cells from oxidative damage. In paracetamol overdose, it replenishes glutathione stores, allowing the liver to detoxify the harmful metabolite NAPQI.
