A method for screening for various sedative-hypnotics in serum by liquid chromatography/single quadrupole mass spectrometry.
A screening method for the detection of sedative-hypnotics in serum is described. The target drugs, which include practically all the sedative-hypnotics distributed in Japan, consisted of 5 barbiturates, 30 benzodiazepine-related drugs and 11 other sedative-hypnotics (i.e., apronalide, bromisovalum, chloral hydrate, triclofos, chlorpromazine, promethazine, diphenhydramine, hydroxyzine, zopiclone, zolpidem and tandospirone). Thirty-nine analytes, selected in terms of the pharmacokinetics of the target drugs, in human serum were screened using a combination of mixed-mode solid-phase extraction and liquid chromatography/electrospray-ionization single-quadrupole mass spectrometry. The detection limits (non-basic analytes, 1-50 ng/ml; basic analytes, 0.1-5 ng/ml) were sufficient to permit the screening of a single therapeutic administration of a target drug.
