Evidence that serotonin3 (5-hydroxytryptamine3, 5-HT3) antagonists attenuate behavioral responses to D-amphetamine and cocaine suggests that 5-HT3 receptors modulate brain dopamine in animals. This study examined the potential interactions of the 5-HT3 antagonist ondansetron and D-amphetamine in 10 healthy human volunteers. After the subjects were(More)
Obsessive-compulsive disorder (OCD) has been linked to abnormal function of brain serotonin (5-HT) pathways. Since ondansetron is a highly selective 5-HT3 receptor antagonist, the present study was undertaken to investigate 5-HT3 function in OCD. We administered m-CPP (0.08 mg/kg i.v.) and the potent 5-HT3 antagonist, ondansetron (0.15 mg/kg i.v.), to 11(More)
Several serotonin3 (5-HT3) antagonists have been shown to attenuate the anxiogenic effects of the serotonergic agent, m-chlorophenylpiperazine (m-CPP), in animal models, but little data regarding possible effects of 5-HT3 antagonists on responses to m-CPP are available from studies in humans. Therefore, we studied the behavioral, physiological and(More)
