On the basis of a recent literature search, this case represents the first report of mania associated with ziprasidone. Despite reports of the induction of mania by atypical antipsychotics, many authors find these agents (including ziprasidone5) helpfulin treating manic symptoms seen in bipolar and schizoaffectivedisorders. In a review of risperidone/olanzapine-induced mania, it was speculated the cause was due to 5-HT /D receptor occu- pancy.6 However, ziprasidone differs from the older atypicalsin its profound 5-HT and 5-HT/norepinephrine (NE) reuptake inhibition effect—similar to amitriptyline and imipramine.
