Background: Pregabalin (PRG) has been abused due to its availability and its cheap price. This study is aimed to test the postmortem stability of PRG in blood specimens. Materials and Methods: Ninety-six male rats were divided into four groups, which were given oral doses of PRG: 4 g and 2.5 g/kg for 1 day; 50 mg and 20 mg/kg/day for 21 consecutive days. Antemortem PRG stability was assessed at 4 and 6 h after the last ingested dose, while postmortem stability was assessed at 24 and 48 h after death using gas chromatographymass spectrometry. Results: Our study could detect that -80°C was a storage temperature that could reserve PRG stability in antemortem and postmortem blood samples. The increase in oral PRG dosage was accompanied with a significant increase in blood PRG concentration. Postmortem PRG blood concentrations were decreased in comparison to antemortem concentrations. However, this decrease did not highlight a statistically significant difference in PRG stability (P < 0.05) at the tested storage condition. Conclusion: PRG analysis could be performed in a peripheral blood specimen within 2 days of sampling.
