Area of Science:

  • Pharmacology
  • Toxicology
  • Gastroenterology

Background:

  • Colchicine, an alkaloid, is a long-standing treatment for acute gout flares.
  • Its therapeutic effect stems from inhibiting inflammatory cell migration and cytokine action.
  • It also reduces lactic acid production and uric acid deposition in tissues.

Observation:

  • Colchicine toxicity, though rare, can have severe health consequences.
  • Prompt gastric decontamination (gastric lavage, activated charcoal) is crucial.
  • Supportive measures, hydration, and electrolyte replacement are vital.

Findings:

  • This case report details a patient with a colchicine overdose due to suicidal intent.
  • Colchicine inhibits cell division, leading to distinct toxicity stages.
