Enrollment: 10
Study Start Date: February 2009
Study Completion Date: April 2010
Primary Completion Date: April 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Post bariatric surgery
Roux en Y bariatric surgery
Procedure: bariatric surgery
Roux en Y bariatric surgery
Control
No surgery

Detailed Description:
Secondary objectives include the determination of changes in mean CPmax, Time to CPmax and Volume of Distribution between the two groups. Also, assessment of subject tolerance of sertraline utilizing the UKU side effect rating scale.
