OBJECTIVE: To compare the relative efficacy and safety of lesopitron 40–80 mg/d versus lorazepam 2–4 mg/d and placebo in a subgroup of patients with anxiety history taken from a larger study of patients with a primary diagnosis of generalized anx

In line with the idea that cholecystokinin (CCK) is involved in anxiety-related behaviours, previous investigations showed that stressful conditions and an 'anxiogenic' drug, yohimbine, increased the cortical release of CCK like-material (CCKLM) in a

1 The ability of 5-HT2 and 5-HT4 receptor antagonists to modify the disinhibitory profile of diazepam and other agents was investigated in male BKW mice in the light/dark test box. 2 The 5-HT2A/2B/2C receptor antagonists ritanserin, MDL11939 and RP62

We have studied the effects of the neuroleptic haloperidol and the non-benzodiazepine anxiolytics buspirone and lesopitron on the expression of c-Fos immunoreactivity in the rat forebrain. Haloperidol and buspirone administration resulted in a signif

Lesopitron, a 5-hydroxytryptamine 1A agonist, is a new potential anxiolytic of the azapirone class. It has greater potency in animal models of anxiety than buspirone, gepirone, or ipsapirone, and it lacks the antidopaminergic effects associated with

A new labelling approach of haptenic drugs with digoxigenin for the development of competitive enzyme immunoassay (EIA) is reported. It consists of the covalent linking of the hapten to the preactivated digoxigenin derivative and revealing the immune

This study evaluated the pharmacological and behavioral effects of S 21,357, a drug with high affinity for both 5-HT1A and 5-HT2A receptors. The drug behaved as antagonist at both 5-HT1A autoreceptors and postsynaptic 5-HT1A receptors, as it prevente

A totally automated liquid chromatographic assay method based on a Prospekt solid-phase extraction unit was developed for the analysis of lesopitron and its metabolite 5-hydroxylesopitron in human plasma. On-line solid-phase extraction of lesopitron,

Previous studies have shown that the 5-HT1A receptor ligand, lesopitron (E-4424, 2-[4-[4-(4-chloro-1-pyrazolyl)butyl]-1-piperazinyl]pyrimidine), exerts potent anxiolytic-like effects in rodents and monkeys (Costall et al., 1992, J. Pharmacol. Exp. Th
