✦ Synopsis

The d.s.c. curves of commercial samples of methaqualone-QuZlude (U.S.A.), ..-Quaalude (Mexico), Sopar, Mandrax and Parcst -are presented. Similar d.s.c. curves were found for Quaalude (U.S.A.), QuFalude (Mexico), and Mandrax, while Sopar and Parest exhibited different types of curves. New and old formulations of the QuZlude (U.S.A.) brand could be differentiated by differences in the tablet filler and binder. Unfortunately. d.s.c. could not be used to determine the country of origin of the drug, although it was useful to characterize it. The technique can be used to identify samples of 0.15 mg or less.
