Wellbutrin XL Effects on SSRIs Induced Changes

• Status: Completed
• Trial end date: 2007-11-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to find out differences in activation of mood regulating areas of the brain in response to negative and positive pictures, before and after 6 weeks of additional Wellbutrin XL treatment. Participants should have been treated for depression with an SSRI medication (e.g., Prozac, Zoloft, Paxil, Celexa or Lexapro) and have decreased depression symptoms but also be experiencing side effects of medications such as sexual side effects and feelings of apathy (indifference, lack of interest) and lack of full emotional response. We will first take a brain scan to measure activity in different parts of the brain, while subjects are seeing pictures, using Magnetic Resonance Imaging (MRI) scan. Then we will add Wellbutrin XL - another well-known antidepressant that acts by increasing the chemical dopamine in the brain, to subjects' treatment. Wellbutrin addition is useful in decreasing the sexual side effects of SSRIs. After treatment with Wellbutrin XL for 6 weeks subjects will have a second MRI scan with picture rating.
