title: [The biotransformation of fenetylline].
abstract: After oral administration of 3,7-dihydro-1,3-dimethyl-7-2 [(1-methyl-2-phenylethyl)-amino-ethyl]-1H-purine-2,6-dione (fenetylline, Captagon), 7 new metabolites could be detected in urine besides 4 known substances. The metabolites were identified by gas chromatography (GC) and by comparison of the mass spectra (MS) of metabolites with those of authentic reference compounds using a combined GC/MS method.
