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

Pharmaceutical research, 5(6), 365-368 (1988-06-01)
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

Drug metabolism and disposition: the biological fate of chemicals, 12(4), 452-459 (1984-07-01)
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
K Schaffler et al.
Arzneimittel-Forschung, 39(2), 276-283 (1989-02-01)
To assess pharmacodynamic and pharmacokinetic properties of acute, subchronic and withdrawn quazepam, a single-blind, longitudinal study was run in eight male, healthy young volunteers. The design covered a 1-week placebo run-in period, a period with daily oral night-time administration of
J M Hilbert et al.
Clinical pharmacology and therapeutics, 36(4), 566-569 (1984-10-01)
The kinetics of quazepam, a benzodiazepine hypnotic, was studied in 10 geriatric subjects. Each received one 15-mg tablet of quazepam. Blood samples were collected before and at specified times (up to 672 hr) after dosing. Plasma concentrations of quazepam and
