Abstract:
At present, there is no specific antidote for colchicine intoxication, and 0.8 mg/kg is its lethal dose. The prognosis of colchicine intoxication patients is closely related to the dosage, but the individual difference is very great. A 38-year-old man with colchicine poisoning was admitted to the Seventh People's Hospital of Shanghai University of Traditional Chinese Medicine, who had ingested 80 mg colchicine tablets (1.19 mg/kg) orally for 4 hours. He was immediately put on gastric lavage, enema, and catharsis. Continuous blood purification was performed for 34 hours and 22 minutes, with a combination of hemoperfusion (HP) and continuous veno-venous hemofiltration dialysis (CVVHDF). He also received a large dose of the glucocorticoid with 80 mg of methylprednisolone injected intravenously every 8 hours and organ function support. The patient was hospitalized for 2 weeks and discharged with improvement. The successful treatment of this case was reported for reference.

Enhanced Elimination of Poison
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.

Antidotes
Specific antidotes operate by inhibiting the enzymes that control biochemical pathways, reducing the production of harmful metabolites.
