Is Napqi a free radical?
Paracetamol (Acetaminophen, PC) is metabolized in liver to N-acetyl-p-benzoquinon-imine (NAPQI), that is in turn conjugated by glutathione S-transferase with glutathione. … The oxidation of paracetamol to quinine form can also generate free radicals. Both above mentioned processes, can injure the mitochondria and cells.
Why is Napqi toxic?

What does Napqi do to cells?
NAPQI primarily targets mitochondrial proteins and ion channels leading to the loss of energy production, ion misbalance and cell death [5,9,11]. Following animal studies, N-acetylcysteine (NAC) was shown to be an effective antidote for acetaminophen overdose in humans .
