The influence of replacement of the <i>N</i>-ethyl group by the cyanoethyl group on the absorption, distribution and metabolism of (±)-ethylamphetamine in man

Abstract

Abstract N-2-Cyanoethylamphetamine in man was metabolized rapidly and extensively, as indicated by the analysis of the drug and its metabolite in urine, under acidic and normal conditions. A comparison with the excretion and metabolism of ethylamphetamine under comparable conditions was made. The results were assessed using an analogue computer; a simple one compartmental model sufficed to describe the excretion and metabolism of ethylamphetamine and amphetamine but the additional programming of free amphetamine was necessary for cyanoethylamphetamine because of its very rapid metabolism to amphetamine.
