A fatal overdose with colchicine

Area of Science:

• Pharmacology
• Toxicology
• Analytical Chemistry

Background:

• Colchicine is a medication used to treat gout and familial Mediterranean fever.
• Overdose can lead to severe toxicity and death.
• Accurate blood concentration monitoring is crucial for managing colchicine toxicity.

Observation:

• A 39-year-old female ingested an oral overdose of colchicine.
• Blood sample analysis 2 hours post-ingestion revealed a colchicine concentration of 250 microgram/L.
• No detectable colchicine levels were found in blood samples taken at 40 hours post-ingestion.

Findings:

• The study quantifies colchicine blood concentration following an overdose.
• It demonstrates the rapid elimination or distribution of colchicine from the blood.
• The analytical method involved liquid chromatography with UV detection.

Implications:

• This case highlights the importance of timely blood concentration analysis in colchicine overdose.
• Understanding colchicine pharmacokinetics is vital for clinical management and prognosis.
• The findings contribute to the toxicological database for colchicine poisoning.
