Abstract

Ethylamphetamine and two major metabolites in urine, obtained after intraperitoneal administration of the drug to rats, have been isolated by gas chromatography-mass spectrometry. We have also synthesized an authentic sample of p-hydroxy-N-ethylamphetamine by a simple method. In rat, the metabolic pathway of ethylamphetamine is similar to that of amphetamine and methylamphetamine according to quantitative analysis of the major metabolites using a selected ion monitoring (SIM) method.
