Acute Mania, Bipolar Disorder, Manic
Conditions
Brief summary
The purpose of this study is to compare the efficacy and tolerability of ziprasidone versus olanzapine in the treatment of acute mania. An open label extension will further evaluate the efficacy, safety, and tolerability of ziprasidone compared with olanzapine. Study recruitment was stopped due to difficulty in enrolling the targeted number of patients on July 30, 2007. Subjects that were enrolled at the time completed the study as per protocol. There were no safety concerns involved in the decision to stop enrollment. The Last Subject Last Visit was January 10, 2008.
Interventions
Ziprasidone will be initiated at 80 mg/day on Day 1 and titrated to 120 mg/day from Day 3. From Day 7 the dosage may be adjusted on the basis of clinical status between 120 and 160 mg/day.
Olanzapine will be started at 15 mg/day on Day 1 until Day 7. The dosage will then be adjusted on the basis of clinical status between 15 and 20 mg/day.
