BACKGROUND In recent decades, benzodiazepine (BZD) prescriptions have been called into question in most European countries by physicians and health authorities alike, and guidelines on medical indications and treatment duration have been established to avoid long-term use and dependency. In France, many public policy measures have been implemented as BZDs are among the most prescribed medicatio...

PURPOSE The authors studied the sleep of patients with insomnia who complained of poor sleep despite chronic use of benzodiazepines (BZDs). The sample consisted of 19 patients (mean age 43.3+/-10.6 years) with primary insomnia (DSM-IV), who had taken BZDs nightly, for 7.1+/-5.4 years. The control group was composed of 18 healthy individuals (mean age 37+/-8 years). Sleep electroencephalogram (E...

As there is no multidimensional instrument available that reflects the severity of benzodiazepine (BZD) dependence comprehensively, the Benzodiazepine Dependence Self-Report Questionnaire (Bendep-SRQ) was developed and investigated. The Bendep-SRQ, Symptom Checklist-90 (SCL-90), Schedules for Clinical Assessments in Neuropsychiatry (SCAN), and Addiction Severity Index-Revised (ASI-R) were admin...

Benzodiazepines (BZDs) are among the most widely prescribed drugs in developed countries, but they have a high potential for tolerance, dependence and misuse. High-dose BZD misuse represents an emerging addiction phenomenon, but data on quality of life (QoL) in high-dose BZD misusers are scant. This study aimed to explore QoL in high-dose BZD misuse. We recruited 267 high-dose BZD misusers, com...

Benzodiazepines (BZDs) exert their therapeutic actions by binding to the GABA(A) receptor (GABA(A)R) and allosterically modulating GABA-induced chloride currents (I(GABA)). A variety of ligands with divergent structures bind to the BZD site, and the structural mechanisms that couple their binding to potentiation of I(GABA) are not well understood. In this study, we measured the effects of indiv...

PURPOSE There have been no data about long-term benzodiazepine (BZD) use and its correlates in patients with major depressive disorder (MDD) in China. This study aimed to examine the prevalence of long-term BZD use (more than three months) and its demographic and clinical correlates in Chinese patients with MDD. DESIGN AND METHODS A total of 1,192 patients with MDD were examined in 10 mental ...

OBJECTIVE To review the efficacy of anxiolytics (alprazolam and azapirones) in major depressive disorder (MDD) and that of antidepressants in generalized anxiety disorder (GAD), thereby exploring the possible theoretical and clinical implications of this efficacy. METHOD A Medline literature search was performed for the period January 1980 to September 1997 of randomized, double-blind compari...

Benzodiazepines (BZDs) are widely used in clinical practice as anxiolytics, hypnotics, anticonvulsants, and muscle relaxants. However, they have some undesired effects including memory problems. In continuing our research on novel benzodiazepine ligands, we are looking for ligands with less adverse effects. Previously, 4 novel derivatives of 2-phenoxy phenyl-1,3,4-oxadiazole were synthesized as...

Benzodiazepines (BZDs) exert their effects in the CNS by binding to a modulatory site on GABAA receptors. Individual amino acids have been implicated in BZD recognition and modulation of the GABAA receptor, but the secondary structure of the amino acids contributing to the BZD binding site has not been elucidated. In this report we used the substituted cysteine accessibility method to understan...
