A double-blind, placebo-controlled, multicenter study, was performed to evaluate the efficacy and safety of ziprasidone in 139 patients with an acute exacerbation of schizophrenia or schizoaffective disorder. Patients were randomized to receive ziprasidone 40 mg/day, 120 mg/day or placebo for 28 days. Ziprasidone 120 mg/day was significantly more effective than placebo in improving the BPRS total, CGI-S. BPRS depression cluster and BPRS anergia cluster scores (all P < 0.05). Similarly, the percentages of patients classified as responders on the BPRS (> or = 30% reduction) and the CGI improvement (score < or = 2) were significantly greater with ziprasidone 120 mg/day compared with placebo (P < 0.05). The number of patients who experienced an adverse event was similar in all three treatment groups, and discontinuation due to adverse events was rare (five of 91 ziprasidone-treated patients). The most frequently reported adverse events, that were more common in either ziprasidone group than in the placebo group, were dyspepsia, constipation, nausea and abdominal pain. There was a notably low incidence extrapyramidal side-effects (including akathisia) and postural hypotension and no pattern of laboratory abnormalities or apparent weight gain. Ziprasidone-treated patients were not clinically different from placebo-treated patients on the Simpson-Angus Rating scale, Barnes Akathisia scale and AIMS assessments. These results indicate that ziprasidone 120 mg/day is effective in the treatment of the positive, negative and affective symptoms of schizophrenia and schizoaffective disorder with a very low side-effect burden.

In this double-blind study, patients with an acute exacerbation of schizophrenia or schizoaffective disorder were randomized to receive either ziprasidone 80 mg/day (n = 106) or 160 mg/day (n = 104) or placebo (n = 92), for 6 weeks. Both doses of ziprasidone were statistically significantly more effective than placebo in improving the PANSS total, BPRS total, BPRS core items, CGI-S, and PANSS negative subscale scores (p < .05). Ziprasidone 160 mg/day significantly improved depressive symptoms in patients with clinically significant depression at baseline (MADRS > or = 14, over-all mean 23.5) (p < .05) as compared with placebo. The percentage of patients experiencing adverse events was similar in each treatment group, and resultant discontinuation was rare. The most frequent adverse events associated with ziprasidone were generally mild dyspepsia, nausea, dizziness, and transient somnolence. Ziprasidone was shown to have a very low liability for inducing movement disorders and weight gain. The results indicate that ziprasidone is effective and well tolerated in the treatment of the positive, negative, and depressive symptoms of an acute exacerbation of schizophrenia or schizoaffective disorder.

Ziprasidone is an atypical antipsychotic with affinity to the D2, 5HT2A, 5HT2C, 5HT1A, 5HT1B/1D receptors. It is available in both oral and intramuscular forms. It is well absorbed from the digestive tract and its absorption increases after the meal. Ziprasidone is used for the treatment of schizophrenia and bipolar manic states in doses 40-80 mg administered twice a day. The i.m. form should be given 40 mg/day only during three days. Ziprasidone shows similar an efficacy toward the positive symptoms as olanzapine. The i.m. form of ziprasidone showed better efficacy toward psychotic symptoms and lower risk for extrapyramidal symptoms than haloperidol. It is well tolerated. The most frequent side-effects are somnolence, nausea, and dyspepsia. The risk for metabolic side-effects was low. In some patients treated with ziprasidone, the prolongation of the QTc was noted.
