title: Changed compounds of hydroxyzine in a human urine.
abstract: During a forensic toxicological GC/MS screening, changed compounds of hydroxyzine were found in a man's urine taken about 20 h after ingesting sake (Japanese liquor) and tranquilizers. The structures of those compounds were assigned to 4-chlorodiphenylmethane(I), p-chlorbenzophenone(III), norchlorcyclizine(IV), 7-(p-chloro-alpha-phenylbenzyl)-2-hydroxy-2H,3H-oxazolo-[3,2 -alpha] piperazine(V), 1-(p-chloro-alpha-phenylbenzyl)-4-methylpiperazine-3-one(VI), N-(p-chloro-alpha-phenylbenzyl)-N'-formylmethyl-N'- hydroxyethyl-1,2-ethenediamine(VII) and 1-(p-chloro-alpha-phenylbenzyl)-4-[2-ethoxy(2-ethoxy)-ethyl] piperazine(VIII) on the basis of the fragmentation patterns and relative retention times except VIII which was identified using the synthesized compound. I, V, VI, VII and VIII have not been reported previously, but the possibility of metabolites of hydroxyzine is still uncertain.
