Case Reports
Markedly altered colchicine kinetics in a fatal intoxication: examination of contributing factors.
1. Colchicine poisoning, which is relatively rare, is associated with significant morbidity and mortality. Whilst a new treatment modality, in the form of colchicine-specific Fab fragments is on the horizon, currently available therapy is largely supportive. 2. ⋯ Josamycin, one of the co-ingestants and an inhibitor of P-glycoprotein, the membrane pump responsible for multidrug resistance, may have played a significant role in impeding the cellular and biliary elimination of colchicine. Co-ingested opioid and anticholinergic compounds may have altered colchicine absorption and gastrointestinal transit. 6. This case serves as a reminder of the need for attention to co-ingested drugs, to early aggressive therapy, and if available, to consideration of immunotherapy.
