RESUMEN
Objective The method for the analysis of Methylenedioxypyrovalerone (MDPV) in urine by liquid-phase small-extraction- GC/MS have been developed and studied . Methods A 1-mL of urine sample was adjusted to pH9 with sodium bicarbonate, and was extracted with 50μL dichloromethane. The mixture centrifuged at 14000g for 2 min . A 1-μL organic phase was injected into the GC/MS system. Results The calibration curves showed good linearity in range of 0.05μg/mL~0.20μg/mL , and the limit of detection was 0.02μg/mL, and the RSD was 3.86~5.69%, and the recovery rate was 86.5~92.8 %. Conclusion The method is sensitive, accurate and was easy to operate for fast detection of MDPV in human urine.
RESUMEN
BACKGROUND:The use and abuse of designer drugs has been recognized for decades;however there are many derivatives of compounds that make their way into the community. Abuse of compound(s) known on the street as "bath salt" is on the rise. METHODS:We report the case of a 33-year-old man who complained of "flashbacks"and right arm shaking that followed a night of "bath salt" snorting. The active compound methylenedioxypyrovalerone methamphetamine (MDPV) was confirmed; however, analysis of three different "bath salt" products showed difference in their active components. RESULTS:The patient's symptoms remained stable and he was discharged home after observation in the emergency department with instructions to return for any symptom progression. CONCLUSION:Practitioners should be aware of the abuse of the compounds and that not all"bath salt" products contain MDPV.
