Description
Summary:Ecstasy is one of the popular illicit drugs in the world and its usage has been recently increased in Iran. This compound can destroy the serotonergic neurons and produces cognitive and psychopathology diseases. 3,4-dihydroxymethamphetamine (HHMA), which is the main metabolite of this compound, seems to be responsible for this effect. In this study, the stability of this crucial metabolite of ecstasy was examined in different mediums. The stability of HHMA was studied in the perfusion medium and water at 100 and 10 ng/mL concentrations. Moreover, the effect of temperature (0-25 degrees C), pH (3-10), calcium chloride (0-150 g/L) and ethylenediaminetetraacetic acid (EDTA) on the stability of HHMA was also examined. The result suggested that the free form of HHMA could be degraded in the perfusion medium. The rate of this degradation has direct proportion to temperature (at 25 degrees C = 0.037 min^sup -1^ and at 0 degree C = 0.002 min^sup -1^). Although, while degradation was prevented at pH=3, EDTA could only reduce this rate about 30%.
