title: Norephedrines as metabolites of ( 14 C)amphetamine in urine in man.
abstract: (+/-)-[(14)C]Amphetamine sulphate (20mg) was administered orally to each of two human male subjects, and 80-85% of the (14)C was excreted in the urine in 2 days. The metabolites in the first day's urine were examined quantitatively. Apart from the metabolites previously described (Dring et al., 1970), norephedrine (2.2 and 2.6% of dose in the two subjects respectively) and 4-hydroxynorephedrine (0.3 and 0.4% of dose in the two subjects respectively) were also found.
