Developing new antidotes for poisons with existing effective treatments: a case study of fomepizole in paracetamol poisoning

Acetylcysteine is the only effective and licensed therapy for paracetamol poisoning. However, acetylcysteine loses efficacy if treatment is delayed 8-12 hours after paracetamol ingestion, and there is also uncertainty as to whether the dose should be increased in high-risk paracetamol ingestions.

Abstract Acetylcysteine is the only effective and licensed therapy for paracetamol poisoning. However, acetylcysteine loses efficacy if treatment is delayed 8-12 hours after paracetamol ingestion, and there is also uncertainty as to whether the dose should be increased in high-risk paracetamol ingestions. Studies have identified potential therapeutic targets, including enzymes that metabolize paracetamol; the pathways causing mitochondrial toxicity via c-Jun N-terminal kinases or superoxide generation; and other specific targets, such as nuclear factor-erythroid factor 2-dependent gene induction and autophagy. With this range of potential additional therapies, how should the speciality of clinical toxicology approach the development of new antidotes for this common poisoning?INTRODUCTIONAcetylcysteine is the only effective and licensed therapy for paracetamol poisoning.
