In this study, regional tissue distributions of the amphetamine analogue 3,4-methylenedioxymethamphetamine (MDMA, "ecstasy") and its metabolite 3,4-methylenedioxyamphetamine (MDA) in a fatal overdose are presented. Quantitation of MDMA and MDA levels occurred in blood samples taken centrally (right and left heart and main adjacent great vessels) and peripherally (subclavian and femoral blood)....
A controlled study was undertaken to determine the stability of the designer drugs MDA, MDMA and MDEA in pooled serum, whole blood, water and urine samples over a period of 21 weeks. The concentrations of the individual designer drugs in the various matrices were monitored over time, in the dark at various temperatures (-20, 4 or 20 degrees C), for a low (+/- 6 ng/ml for water, serum and whole...
Abstract Background: The popular designer drugs 3,4-methylenedioxymethamphetamine (MDMA) and 3,4-methylenedioxyethylamphetamine (MDEA) can be determined in serum, whole blood, and urine, but also in vitreous humor. The latter matrix is interesting when dealing with decomposed bodies in a toxicological setting. Methods: After extraction, chromatographic separation was achieved on a narrow-bore...
