title: Blood cocaine and metabolite pharmacokinetics after cardiac arrest in a body-packer case.
abstract: BACKGROUND
  Cocaine body packing, the internal concealment of cocaine for transportation between countries, may expose to life-threatening intoxications. No data is currently available on the pharmacokinetics of cocaine and its metabolites when a packet rupture occurs in a body packer.
  
  
  METHODS
  We report the first pharmacokinetic data associated with a severe cocaine intoxication in a body packer, resulting in cardiac arrest. Massive concentrations of cocaine (observed maximal concentration: 1.66 mg/L, 1 hour after the cardiac arrest) were measured in plasma up to about 15 hours, suggesting a prolonged absorption due to a slow-release in the gastrointestinal tract despite surgical extraction of the packets. Apparent cocaine elimination half-life was 7.6 hours.
  
  
  CONCLUSIONS
  A prolonged apparent cocaine elimination half-life has been observed. Further pharmacokinetic studies are needed to understand better the pathophysiology of acute cocaine intoxication in body packers.
