The Effects of Vilazodone on Glutamate in the Anterior Cingulate Cortex in Anxious Unipolar Depressives

• Status: Withdrawn
• Trial end date: 2015-04-01
• Target enrollment: 0
• Participant gender: Female

Summary

The purpose of this study is to determine whether vilazodone is more effective than citalopram for the treatment of anxious depression. We will use neuroimaging to see whether there are changes in the brains of patients receiving the drug vilazodone that are different from those of citalopram. These changes may show that vilazodone affects the brain differently than most other kinds of standard antidepressant medications.
