The objective of this work was to establish an analytical method for the analysis of 7 Benzodiazepines (diazepam, oxazepam, temazepam, nordiazepam, desalkylflurazepam, alprazolam and α-hydroxyalprazolam) in urine specimens taken from drivers suspected of driving under the influence of drugs. The

The disposition of 14C-quazepam (7-chloro-(2,2,2-trifluoroethyl) [5-14C]-5-o-fluorophenyl-1,3-dihydro-2H-1,4-benzodiazepin-2-thione), a new benzodiazepine hypnotic, was studied in hamsters and mice after iv and po dosing. In both species, quazepam was rapidly absorbed, as indicated by the plasma Cmax being reached within 1 hr of

We successfully developed and validated an LC-MS/MS method for the identification of 27 and quantification of 9 benzodiazepines and metabolites in whole blood and DBSs. The results provided a good qualitative and quantitative correlation between DBSs stored at room temperature

A new benzodiazepine compound, ethyl loflazepate (ethyl-7-chloro-2,3-dihydro-5-(2-fluorophenyl)-2-oxo-1H,1,4- benzodiazepine-3-carboxylate; CM6912) was studied using in vitro experimental systems for its displacement activity on 3H-diazepam binding to the synaptosomal membrane fraction of rat cerebrum and potentiating action on GABA. CM6912 inhibited the specific
S K Gupta et al.

A reverse-phase liquid chromatographic method is described for simultaneous quantification of quazepam, and two of its metabolites, 2-oxoquazepam and N-desaklyl-2-oxoquazepam. The method uses a solid-phase extraction procedure to prepare plasma samples. After extraction, the methanolic extract is evaporated; the residue
