title: Determination of some butyrophenones in body fluids by gas chromatography with surface ionization detection.
abstract: Haloperidol, moperone, pipamperone and bromperidol were found measurable with high sensitivity by gas chromatography (GC) with surface ionization detection (SID). The calibration curves using moperone as internal standard were linear in the range of 0.4-4 pmol on column for haloperidol, pipamperone, and bromperidol. The detection limit of the drugs was about 0.1 pmol on column. For their actual determination with forensic samples, a detailed procedure for their extraction from human whole blood and urine was established with Sep-Pak C18 cartridges. The recovery of the 4 drugs, which had been added to whole blood and urine, was more than 90%. Haloperidol in whole blood and urine of a schizophrenic patient, who had been administered with this drug (3 mg/day p.o.), could be quantitated by the present GC-SID, and the levels were 7.18 and 43.2 pmol/ml, respectively.
