This study aims to determine the difference, if any, in the pharmacokinetics of duloxetine between patients who are nine to fifteen months post Roux-en-Y Bariatric Surgery and control subjects matched for body mass index (BMI), age and gender.
||Endpoint Classification: Bio-availability Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Basic Science
||A Preliminary Comparison of the Effect of Roux-en-Y Bariatric Surgery on Blood Levels of Duloxetine
Primary Outcome Measures:
- The difference, if any, in the pharmacokinetics parameters (Cmax, Tmax, AUCo-inf, t1/2, CL/F, Vd/F) of duloxetine between patients who are nine to fifteen months post Roux-en-Y Bariatric Surgery and control subjects matched for BMI, age and gender. [ Time Frame: 4 days ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- Assessment of subject tolerance of duloxetine utilizing the UKU side effect rating scale. [ Time Frame: 4 days ] [ Designated as safety issue: Yes ]
