| Brief Title † | Bipolar II Depression: Lithium, SSRI, or the Combination | ||||
| Official Title † | Comparing the Safety and Effectiveness of a Mood Stabilizing Medication, an Antidepressant Medication, and a Combination of Both Medications to Treat Symptoms of Bipolar Type II Depression | ||||
| Brief Summary | This study will compare the safety and effectiveness of a mood stabilizing medication, an antidepressant medication, and a combination of both medications to treat symptoms of bipolar type II depression. |
||||
| Detailed Description | Bipolar type II depression (BD II) is a less severe type of bipolar disorder. BD II is characterized by one or more depressive episodes and at least one hypomanic episode. During hypomanic episodes, people experience especially energetic or anxious moods, and their thoughts are more sporadic than usual, but they do not experience the severity of mania. Symptoms of BD II are known to impair daily functioning as well as cause distress and even suicide. Antidepressant medication alone is not recommended for people with bipolar disorder because manic symptoms usually worsen. It is unknown whether the same recommendation should apply to people with BD II. Sertraline is a selective serotonin reuptake inhibitor (SSRI) antidepressant that increases levels of serotonin, helping the brain to maintain mental stability. It is often used to treat depression, panic attacks, and other disorders. Lithium is a mood stabilizing medication that decreases abnormal brain activity and is used to treat and prevent recurring episodes of mania in people with bipolar disorders. This study will evaluate the effectiveness of lithium alone, sertraline alone, and lithium with sertraline to treat symptoms of BD II. Participation in this double-blind study will last up to 18 weeks. Participants will be randomly assigned to receive either lithium, sertraline, or lithium and sertraline. Both medications will initially be given at a low dose and then gradually increased over 2 weeks. For the remainder of the study, dosages will be adjusted as necessary. Study visits will occur every week for the first 6 weeks and then every other week for the remaining 10 weeks. During all study visits, participants will complete a psychiatric assessment and questionnaires about their current mood and any treatment side effects. Urine and blood collection may occur at selected times during the study. |
