Zolpidem [N,N,6-trimethyl-2-(4-methylphenyl)imidazo[1,2-a]pyridine-3-acetamide hemitartrate] is reported to be a rapid onset, short duration hypnotic that interacts at the benzodiazepine recognition site. The present report establishes the neuropsychopharmacological profile of zolpidem and compares it with those of benzodiazepine hypnotics. Although in mice(More)
Progabide and its immediate metabolite SL 75102 displace [3H]gamma-aminobutyric acid (GABA), [3H]muscimol and [3H]isoguvacine from their binding sites to membranes prepared from rat brain or human cerebellum and increase (SL 75102) [3H]flunitrazepam binding to rat cerebral cortex membranes. In contrast, these compounds have very weak or no effects on alpha(More)
From the data discussed in this review it appears that GABA receptor agonists exhibit a variety of actions in the central nervous system, some of which are therapeutically useful (Table V). GABA receptor agonists, by changing the firing rate of the corresponding neurons accelerate noradrenaline turnover without changes in postsynaptic receptor density and(More)
In gallamine-immobilized cats, the caudate nucleus and the nucleus accumbens septi were perfused by means of a push-pull cannula and dopamine was measured in the perfusate. Chlorpromazine (10 mg kg(-1)) and clozapine (20 mg kg(-1)), administered intravenously, enhanced the release of dopamine. The effect of chlorpromazine was similar in both regions whereas(More)
Progabide, a new antiepileptic GABA agonist of moderate affinity for GABA receptors, has been studied in a number of psychiatric disorders and the results compared with the action of this drug in animal models. In an animal model for anxiety (the aversive response to periaqueductal grey stimulation in the rat) progabide had a similar action to that of(More)
