[Analysis and renal excretion of pirisudanol (Stivane)]

The chromatographic and spectroscopic properties (TLC; UV; IR; 1H-NMR; GC/MS) of the psychostimulant Stivane (dimaleate;I) are presented in detail, describing some analytic peculiarities of the pure substance as well. Moreover, the results of the renal excretion studies are reported: after hydrolysis in each of the acidic and basic urine extracts a degradation product--but no unchanged drug--could be detected.
