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

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 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-(+)

The 5-HT(2A/2C) receptor antagonist, ritanserin, was reported to retard the acquisition of conditioned responses (CRs) during classical conditioning of the rabbit's nictitating membrane (NM) response. The present study compared the effects of ritanserin on acquisition of CRs to a tone

Associative learning during classical trace eyeblink conditioning has been shown to be regulated by serotonin 5-HT(2A )receptors and to be critically dependent on the integrity of frontal cortex. Chronic administration of 5-HT(2A) ligands has been shown to produce a selective
