摘要：

In this study the equine metabolism of fluoxymesterone (9 alpha-fluoro-11 beta-17 beta-dihydroxy-17 alpha-methylandrost-4-ene-3-one) given orally has been investigated. The parent material was not detected, but two major 16-hydroxy metabolites which corresponded to a mono- and a di-hydroxylation product were evident. One of the hydroxylation positions was identified as C-16. Phase II metabolism in the form of glucuronide formation was also common. These steroids will provide target compounds for confirming abuse of this drug in the horse. (C) 1997 Elsevier Science B.V.
