Abstract

Fluoxymesterone, an anabolic steroid, is metabolized in man primarily by 6β-hydroxylation, 4-ene-reduction, 3-keto-reduction, and 11-hydroxy-oxidation. These pathways of metabolism are suggested by the positive identification of 4 metabolites and the tentative identification of 3 other metabolites. Detection of the drug in urine is possible for at least 5 days after a single 10 mg oral dose to previously untreated adult males, by monitoring the presence of 2 metabolites, since the parent drug is not detectable more than 1 day after the dose.

氟甲睾酮(halotestn®)给药检测:气相色谱-质谱法鉴别尿液代谢物
氟甲睾酮是一种合成代谢类固醇,在人体内主要通过6β-羟基化、4-烯还原、3-酮还原和11-羟基氧化代谢。4种代谢物的阳性鉴定和另外3种代谢物的初步鉴定表明了这些代谢途径。通过监测两种代谢物的存在,在先前未经治疗的成年男性口服单次10mg剂量后至少5天可以在尿液中检测到该药物,因为母体药物在给药后1天以上无法检测到。
