Lamotrigine Effective in Bipolar I Prevention in Adolescents
At the 2014 meeting of the American Academy of Child and Adolescent Psychiatry, researcher Robert Findling reported on a double blind, placebo controlled 36-week study of lamotrigine for children and adolescents with bipolar I disorder. The doses designed for maintenance treatment averaged about 225 mg/day, achieved by very slow increases over time in order to reduce the risk of a serious rash.
Findling found that lamotrigine was more effective than placebo in extending the time until a patient required an intervention for a new mood episode among the older children in the study (aged 13 to 17). Among the younger children in the study (aged 10 to 12), lamotrigine’s effects were not statistically significant compared to placebo. Findling and colleagues concluded that lamotrigine appeared effective in delaying time to onset of a new episode in adolescents with bipolar I disorder.
Lamotrigine is approved by the Federal Drug Administration (FDA) for bipolar disorder in adults only.
