Abstract

In urine, after oral doses of phendimetrazine to man, were found unchanged drug, the N-demethylated metabolite, phenmetrazine, and the N-oxide of phendimetrazine, but not N-hydroxyphenmetrazine; the metabolites were identified using t.l.c. and g.l.c. The stability of the drug and its metabolites in biological fluids and in ether was studied. A gas chromatographic procedure for the quantitative determination of unchanged drug, its N-oxide and phenmetrazine in urine, plasma and saliva was developed, the N-oxide being reduced before analysis.

Zusammenfassung

Nach oralen Dosen von Phendimetrazin an Menschen wurde im Harn unverändertes Phendimetrazin, der N-demethylierte Metabolit, Phenmetrazin und das N-Oxid von Phendimetrazin, nicht jedoch N-Hydroxyphenmetrazin gefunden; die Metaboliten wurden mittels TLC und GLC identifiziert. Die Stabilität von Phendimetrazin und dessen Metaboliten wurde in biologischen Flüssigkeiten und in Ether untersucht. Es wurde eine gaschromatographische Methode für die quantitative Bestimmung von Phendimetrazin, seinem N-Oxid und Phenmetrazin in Harn, Plasma und Speichel entwickelt, wobei das N-Oxid vor der Analyse reduziert wurde.
