Clinical Details

Official title: Combination Therapy in Bipolar Rapid Cycling

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: The Proportion of Patients Who Experience a Marked and Persistent Bimodal Response

Detailed description: Early studies have shown lithium to produce a high percentage of satisfactory clinical response in patients with bipolar disorders. These studies, however, do not include lithium-refractory subgroups, such as bipolar II disorder patients. When the wide spectrum of bipolar disorders is considered, the lithium response rate decreases significantly. More broadly effective regimens are needed. Participants in this study will be randomly assigned to receive either lithium plus divalproex or lithium, divalproex, and lamotrigine for 7 months. Symptoms of depression and mania will be assessed with scales and patient questionnaires.
