title: Simultaneous determination of methamphetamine and its metabolites in monkey urine by gas chromatography/mass spectrometry with selected ion monitoring.
abstract: A sensitive and specific gas chromatography/mass spectrometry (GC/MS) method has been developed for the simultaneous analysis of methampthetamine and its metabolites (amphetamine, p-hydroxymethamphetamine, and p-hydroxyamphetamine) in monkey urine. The method has been applied to the analysis of urine samples from monkeys singly and repeatedly treated with methamphetamine. We have shown that the repeated administration of methamphetamine causes the reduction of urinary excretion of aromatic hydroxylated metabolites. We propose that the method described here can be used for biological monitoring.
