Treatment for Bipolar Depression: Acute & Prophylactic Efficacy With Citalopram
Bipolar depression is one of the least studied depressive illnesses. The standard practice for many doctors is to use antidepressant medicines, but there are few studies on the long-term results of these medicines. The goal of this study is to look at how effective and safe these medicines are in treating bipolar depression when taken with a mood stabilizer medicine.
The drug being studied is citalopram, also known as Celexa. Celexa is FDA approved for the treatment of major depression, but is not FDA approved for the treatment of bipolar depression. It is, however, standard practice for many doctors is to use antidepressants, like Celexa, to treat their patients with bipolar disorder depression.
The drug will be studied in three ways. We will see if it helps treat depressive symptoms. We will see how the drug affects the brain using PET and fMRI scans. Finally, we will look at the possibility that there may be a gene that could predict if a person would get better taking the drug using genetics.

- MADRS Rating Scale Change [ Time Frame: 6 weeks ]Montgomery Asberg Depression Rating scale assessed in mixed effects regression model. The total range for the scale is 0 to 60. Lower values involve less depression, while higher values involve worse depression. The change in the MADRS scale is interpreted as higher values meaning better outcomes, because more depressive symptoms are improved.

Active Comparator: citalopram + mood stabilizer
All patients are on baseline mood stabilizers and are randomized to receive citalopram or placebo. In this arm, they are randomly assigned to citalopram.
Drug: citalopram + mood stabilizer
Citalopram dose will be flexibly designed, beginning at 10 mg/d for at least one week, and the increased by 10 mg per week to a maximum of 50 mg/d. No target dose will be provided but rather clinicians will dose to clinical efficacy. Thus the study will provide clinicians data on the effective dose if it is positive. The dose will not be predetermined at static amounts.
Other Name: Celexa
Placebo Comparator: placebo + mood stabilizer
All patients are on baseline mood stabilizers and are randomized to receive citalopram or placebo. In this arm, they are randomly assigned to placebo
Drug: placebo + mood stabilizer
This arm will only receive mood stabilizing medication. All subjects will be required to receive treatment with lithium, lamotrigine, valproate, or carbamazepine for at least one month at therapeutic blood levels or doses before randomization, or they must initiate one of these agents at study entry.
Other Name: lithium, lamotrigine, valproate, or carbamazepine
