?:abstract
  • N-ethylpentylone (NEP, ephylone, bk-EBDP) was the most prevalent synthetic cathinone detected by the Miami-Dade Medical Examiner Toxicology Laboratory from 2016-2018. There is limited information regarding the toxicity of NEP, however the few published reports suggest that NEP can cause serious toxic effects and sudden death. The purpose of this publication is to describe a validated LC-MS/MS method for seven synthetic cathinones (methylone, ethylone, butylone, dibutylone, α-PVP, pentylone, and NEP) and to present a detailed summary regarding the presence of NEP in postmortem casework at the Miami-Dade Medical Examiner Department. Post-mortem iliac blood, serum, liver, and brain specimens were prepared by solid-phase extraction with analysis by ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS-MS). Analyte linearity was established from 0.01 to 0.5 mg/L on a six-point calibration curve. A total of 101 NEP quantitations were performed using this method. Concentrations in postmortem case samples ranged from 0.01 mg/L to 2.7 mg/L. Iliac blood concentrations averaged 0.312 mg/L with a median of 0.137 mg/L (n=72) across all causes and manners of death. Approximately half of the cases were homicides in which the decedent was the victim of gunshot wounds or stabbing. Two of the three highest concentration cases of NEP (2.7 mg/L and 1.7 mg/L) involved 38-year old white males who were tasered by police prior to death. The psychostimulant effect of NEP may result in an excited delirium and/or hallucinogenic state. The concentration of NEP detected in accidental intoxication and polydrug cases overlapped with those attributed to other causes, including homicides and police involved deaths.
