GABAA receptors belong to the class of pentameric ligand-gated ion channels and are involved in fast inhibitory transmission at synapses in the central nervous system. Benzodiazepines are positive allosteric modulators of the GABAA receptor and are widely prescribed because of their hypnosedative, anxiolytic, anti-epileptic and muscle relaxant effects. Molecular insight into the mechanism of ac...

Patients rarely consult physicians before developing coagulopathy or bleeding in most reported cases of superwarfarin intoxication. A 57-year-old woman ingested red-dyed pellets of anticoagulant rodenticide containing difethialone and warfarin as well as tablets of nitrazepam. Although she presented to the hospital in a comatose state, notable pink-colored excreta hinted at the consumption of a...

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...

Ten subjects (mean age 57 years) took part in a crossover study between a food drink and nitrazepam 5 mg. They rated their anxiety and sleep quality. On half the sleep laboratory nights during baseline periods subjects were given an inert pill which they were told would improve sleep. A comparison was made between the six pill and six non-pill nights for each subject. Subjective ratings reveale...
