The aim of this study was to investigate the correlation between histories of zolpidem and benzodiazepines use and their concentrations in hair as determined by segmental hair analysis, that is, by analyzing hair samples taken 0-1, 1-2, 2-3, 3-4, 4-5

Previous metabolic studies have established that two major metabolites, 2-oxoquazepam and N-desalkyl-2-oxoquazepam, are present in plasma after dosing with quazepam, a new benzodiazepine hypnotic. The excretion of quazepam, 2-oxoquazepam, and N-desalkyl-2-oxoquazepam into human breast milk was studied in four lactating

The Journal of clinical psychiatry, 52 Suppl, 21-26 (1991-09-01)
Quazepam and flurazepam share pharmacokinetic properties that result in prevention of early-morning insomnia, daytime rebound anxiety, and withdrawal rebound insomnia. Yet sleep laboratory and performance studies demonstrated that during a 1- to 4-week administration period quazepam had a low potential
