A binary mixture of trifluoperazine HCl and chlordiazepoxide was determined using reversed-phase liquid chromatography method using methanol:water (97:03, v/v) pumped at a flow rate of 1.0 ml/min. Quantification was achieved with ultraviolet detection at 262 nm over concentration ranges of 0.1-1 and 0.5-5 mug/ml; mean accuracies were 101.05+/-0.47 and 98.97+/-0.33 %, respectively. The method wa...

The present study was designed to evaluate the effects of bulbectomy and acute administration of anxiolytic drugs (diazepam, 10 mg/kg; chlordiazepoxide, 10 mg/kg) on the behavior of both sham-operated and olfactory bulbectomized rats in two tests predictive of anxiolytic activity: plus-maze test and Vogel's conflict test. We investigated also the effect of flumazenil (10 mg/kg), a benzodiazepin...

abstract: In this paper we describe the thin layer chromatographic separation of eight of the most frequently used benzodiazepine derivates (alprazolam, bromazepam, chlorazepate potassium, chlordiazepoxide, diazepam, nitrazepam, oxazepam) and their degradation products after acid hydrolysis. Our aim was not only to develop a simple, rapid and efficient method for their separation but also the o...

The alcohol withdrawal syndrome is charac terised by symptoms such as anxiety, insomnia, anorexia, nausea, tremor, sweating and distur bances in coordination. These symptoms tend to occur within 6 to 12 hours of alcohol-dependent patients stopping or reducing their alcohol in take. Less frequently, convulsions, hallucinosis and delirium tremens can occur. Delirium tremens (disturbed orientation...

The 1,4-benzodiazepines have become the most frequently prescribed of all psychotropic drugs since the introduction of the first member of this series, chlordiazepoxide, into clinical practice in 1960. The compounds are used as anxiolytics, sedative/hypnotics, anticonvulsants, and muscle relaxants. This unique spectrum of activity, together with their large therapeutic index and essential lack ...
