Brief Summary:
This 11-week study aims to determine how genetic factors affect the way African Americans and Caucasians with major depression respond to antidepressant medication [citalopram (Celexa®)].

Condition or disease Intervention/treatment Phase
Depression Drug: Citalopram Phase 4

Detailed Description:

Depressed patients vary substantially in their responses to antidepressants. Genetic factors may account for a large part of these differences in response. This study will include both African Americans and Caucasians to examine the role of genetic factors in treatment response.

Participants receive citalopram (Celexa) for 8 weeks and a placebo for 1 week. Visits occur once a week for 11 weeks. A variety of interviews, scales, tests, and questionnaires are used to assess participants.
