Post-mortem Redistribution of Drugs in Rats

Sources: Laboratory of Pharmacology - CHU Bordeaux


Drug concentration in tissues and body fluids change between the death and the postmortem specimen collections because of post-mortem redistribution. The aim of this study was to investigate post-mortem redistribution of the 2 cardiotoxic antipsychotic drugs: haloperidol and thioridazine, in order to interpret the postmortem redistribution. The rat has been chosen as the animal model.

Those chromatograms present liquid-liquid extraction results obtained from heart samples 6 hours after death. At this time the concentration of haloperidol and thioridazine was respectively 472 ng/g and 1435 ng/g (significant variation).
