Safety And Efficacy Study Of Depakote ER To Treat Pediatric Bipolar Disorder

There is no accepted, well-studied treatment for Pediatric Bipolar Disorder and treatment has often followed from adult studies. The primary objectives for this study are to determine if subjects can safely and easily be switched from divalproex sodium to Depakote ER and to determine if Depakote ER is both safe and effective for pediatric patients with Bipolar I or II. Secondary objectives include determining the serum levels of valproic acid 20 hours after administration of Depakote ER at a steady rate and determining if co-administration of stimulants will effect the serum levels of valproic acid. Thirty subjects, ages 6-17 years, with a diagnosis of Bipolar I or II who are currently asymptomatic, according to a score of less than 10 on the Young Mania Rating Scale, or who desire to change to once daily dosing, or desire to change because of the likelihood of decreased side-effects, will be recruited from our clinic and the community. If subjects have completed baseline evaluations (including diagnostic confirmation), labs, and rating scales and are still eligible to participate, subjects will be switched in one night from twice-a-day divalproex sodium (DVP) to divalproex sodium extended release (DVP ER). The potential benefits of the research are that new information will be added to the field of child and adolescent psychiatry and the possibility that the medication change may result in improved symptoms of mania or side effects of medications related to peak and trough levels. The potential benefits of this study outweigh the possible risks.
