GSH reduces NAPQI, the metabolite responsible for hepatotoxicity in acetaminophen toxicity. Toxic doses increase oxidation into NAPQI, overwhelming glutathione. How does ethanol interfere with acetaminophen metabolism? Image: https: t.co 6EY9dIwLXY Paracetamol (acetaminophen) toxicity occurs when the liver is overwhelmed by a toxic metabolite called N acetyl p benzoquinone imine (NAPQI), which is normally detoxified by glutathione. In overdose, glutathione is depleted, and NAPQI accumulates, leading The role of oxidative stress, inflammation and acetaminophen exposure from birth to early childhood in the induction of autism William Parker, Chi Dang Hornik, Staci Bilbo, Zoie E.
