Atypical antidopaminergic properties of CI-686: A potential antipsychotic agent

Abstract
The effects of the antipsychotic/antidepressant drug CI-686 on apomorphine- and amphetamine-induced stereotypies, dopamine metabolism, neuroleptic binding, and serum prolactin levels were determined. CI-686 displayed profiles of activity in each of these systems that differs markedly from those of other antipsychotics. CI-686's unique preclinical profile suggests a mechanism of action other than dopamine antagonism which could have implications regarding current thinking on the pathophysiology of schizophrenia.
