Ziprasidone in Pediatric Bipolar Disorder

• Status: Completed
• Trial end date: 2009-11-01
• Target enrollment: 0
• Participant gender: All

Summary

This is a 6 week, open-label, blinded-rater, randomized, controlled, pilot study designed to determine the dosing, safety and efficacy of ziprasidone in the treatment of pediatric bipolar disorder (PBD). In this pilot study we are comparing the efficacy of rapid versus slow dose titration of ziprasidone in PBD. The investigators hypothesize that subjects on ziprasidone monotherapy will have a reduction in manic symptoms. Also, the investigators hypothesize that slower titration of ziprasidone will result in lesser side effects which will assist in medication compliance as measured by patient report and pill count.

• Phase: Phase 4
