Distribution Study of 3,4-Methylenedioxymethamphetamine and 3,4-Methylenedioxyamphetamine in a Fatal Overdose

Journal of Analytical Toxicology March 1, 2002 Els A. de Letter, Karine M. Clauwaert, Willy E. Lambert et al. 47 citations

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)....

Determination of the Designer Drugs 3,4-Methylenedioxymethamphetamine, 3,4-Methylenedioxyethylamphetamine, and 3,4-Methylenedioxyamphetamine with HPLC and Fluorescence Detection in Whole Blood, Serum, Vitreous Humor, and Urine

Clinical Chemistry December 1, 2000 Karine M. Clauwaert, Jan F. van Bocxlaer, Els A. de Letter et al. 68 citations

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...
