Ziprasidone in bipolar disorder.
Ziprasidone is a second-generation antipsychotic currently marketed for the treatment of schizophrenia and bipolar mania. It has a unique receptor profile that includes high-affinity antagonist activity at 5-hydroxytryptamine (5-HT) 2A, D2, 1D and 2C receptors, a potent agonist activity at 5-HT1A receptors and a relatively high affinity for the 5-HT and noradrenaline transporters. The efficacy of ziprasidone in bipolar mania (current episode, manic or mixed) has been well demonstrated in three placebo-controlled trials. In a three-arm controlled study, ziprasidone was shown to be efficacious in dysphoric mania, whereas haloperidol was comparable to placebo. Open-label treatment for up to 52 weeks supported the sustained efficacy of ziprasidone in bipolar disorder. Combined with lithium, ziprasidone has been shown to be efficacious as an augmenting agent in the acute treatment of mania, with sustained efficacy up to 1 year. Ziprasidone was very well tolerated by patients with bipolar disorder and did not cause increased weight, glucose or lipid levels.
