Brain Serotonin 5-HT1A Receptor Binding in Schizophrenia Measured by Positron Emission Tomography and [11C]WAY-100635

Abstract
THERE IS CONSIDERABLE evidence for a role of the neurotransmitter serotonin(5-hydroxytryptamine [5-HT]) in the pathophysiologic characteristics of schizophrenia.1-3 Recent interest in 5-HT has been fueled by the fact that novel antipsychotic drugs such as clozapine, olanzapine, quetiapine, risperidone, sertindole, and ziprasidone hydrochloride are potent 5-HT2A receptor antagonists and relatively weaker dopamine D2 antagonists.4 In addition, 5-HT1A and 5-HT2C receptors seem to contribute to the clinical effects of some novel antipsychotic drugs.5
