Identification of nonpolar methotrimeprazine metabolites in plasma and urine by GLC-mass spectrometry.
Two metabolites of methotrimeprazine, the sulfoxide and the demethylated analog, were identified in extracts from patient plasma by combined GLC-mass spectrometry. Methotrimeprazine and its sulfoxide had similar mass spectra but different GLC retention times. In addition to the metabolites found in plasma, two other metabolites, the didesmethyl analog and the monodesmethyl sulfoxide, were identified in a urine extract.
