Summary

The purpose of this study is to evaluate the safety and effectiveness of vilazodone for the treatment of major depressive disorder versus citalopram. Doctors want to determine if vilazodone is effective for the treatment of major depressive disorder in those who have not responded to generic selective serotonin reuptake inhibitors (SSRI), which is a class of anti-depressant drugs such as Prozac, Lexapro, Paxil, or Zoloft. Both vilazodone and citalopram have been approved for the treatment of major depressive disorder. This research is being done because the researchers want to find out if vilazodone works in reducing the symptoms of depression significantly more than a generic SSRI.

Conditions

Interventions

DRUG

Vilazodone

A fixed dose titration (with doses ranging from 10mg to 40mg/day) will be used. Subjects will take 10mg/day for 1 week, 20mg/day for 1 week and then 40mg/day.

DRUG

Citalopram

For those assigned to citalopram, the dose of citalopram will be maximized to 40mg/day. For those assigned to vilazodone, their citalopram dose will be maintained at 20mg/day for 1 week, then reduced to 10mg/day for 1 week, then switched to vilazodone 10mg/day.
