Safety Study of Ziprasidone (Geodon) for the Depressive Mixed State

We plan on enrolling 25 subjects from each of the four sites. After signing a consent form, subjects will be screened and asked to have a physical and specific safety labs done to make sure they can safely participate in the study. After the screening visit, subjects will be randomly, like a flip of a coin, placed into one of two groups. One group will get the study drug, Geodon. The other group will get placebo, a sugar pill. Neither the doctor nor subject will know in which group the subject has been placed. Subjects will see the doctor once a week for 6 weeks. During each visit, we will check and treat any side effects. We will ask questions about mood and go through a number of rating scales and assessments that will look at mood and symptoms. Subjects will also fill out questionnaires at each visit to assess their moods and see how the study is going. At the final visit, subjects will have the same physical exam and lab tests done as in the initial visit.
