The active and inactive stereoisomers of the serotonin (5-HT2) antagonist, MDL 11,939, were used to examine the relationship between the acute effects of 3,4-methylenedioxymethamphetamine (MDMA) on the dopaminergic system and its long-term effects on the serotonergic system. Only the R-(+)

5-Hydroxytryptamine (serotonin; 5-HT)2 receptor agonists such as (+/-)-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI) injected systemically or directly into frontal cortex, elicit stereotyped head movements that are mediated by 5-HT2A receptors. Chronic administration of 5-HT2A receptor antagonists can produce either a down-regulation, e.g., d-2-bromolysergic acid

The purpose of this study was to assess the anxiolytic effect of MDL 11,939, a selective 5-HT2 receptor antagonist, in patients with generalized anxiety disorder. After a 1-week placebo lead-in period, 72 healthy male outpatients meeting DSM-III-R criteria for generalized

The aim of the present study was to investigate the modulation of locus coeruleus neurons by the selective serotonin (5-HT) reuptake inhibitor citalopram using single-unit extracellular recordings in rat brain slices. Citalopram inhibited the activity of a subpopulation of locus

Serotonin 5-HT2A and 5-HT2C receptors have been implicated in the pathophysiology of obsessive-compulsive disorder (OCD) and in the mechanism mediating the anti-compulsive effects of serotonin reuptake inhibitors. Yet it is currently unclear whether activation or blockade of these receptors would
