Bromadiolone toxicokinetics: Diagnosis and treatment implications

Introduction. Ingestion of bromadiolone can lead to prolonged and life-threatening coagulopathy. Traditional treatment of bromadiolone intoxication relies on the coagulation profile. Currently, there is scanty information on bromadiolone elimination kinetics and half-life. Case Report. We report a case of bromadiolone poisoning in a 40-year old female who, by history, ingested four 42.5-gram bags of rat poison (0.005% bromadiolone), equivalent to 8.5 mg bromadiolone (0.17 mg/kg body weight), four days prior to admission. On admission, her prothrombin time was 92.0 seconds, international normalized ratio was 5.7, and activated partial thromboplastin time was 50.2 seconds with no bleeding on clinical examination. The first plasma bromadiolone level (5 days post-ingestion) was 92 ng/mL. Serial measurement of plasma bromadiolone levels confirmed the diagnosis and demonstrated that bromadiolone obeys the elimination kinetic of a two-compartment model with a rapid, fairly steep decline phase (half-life 3.5 days) followed by a slower termination phase (half-life 24 days). Plasma bromadiolone level of less than 10 ng/mL in our patient was associated with a consistently normal coagulation profile without vitamin K1 therapy. Conclusions. There is a lack of information on the toxicodynamics and toxicokinetics of bromadiolone in humans; further studies are needed before the plasma bromadiolone level can serve as one of the logical and safe therapeutic endpoints for vitamin K1 therapy.
