Impact of bariatric surgery on the absorption of venlafaxine
Bariatric Surgery and Pharmacokinetics of Venlafaxine: BAR-MEDS Venlafaxine
This study is trying to see how bariatric surgery affects how well the depression and anxiety medication venlafaxine works for patients getting ready for these surgeries.

What this trial studies
This observational study investigates how bariatric surgery, specifically gastric bypass and sleeve gastrectomy, affects the pharmacokinetics of venlafaxine, a medication used to treat depression and anxiety. It aims to understand changes in gastric pH, gastric emptying time, and gastrointestinal transit-time that may influence the biological availability of the drug. The study is conducted in Central Norway and focuses on patients preparing for these surgical procedures. By analyzing these pharmacokinetic changes, the research seeks to provide insights into medication management for patients post-surgery.
Who should consider this trial
Good fit: Ideal candidates are Norwegian citizens preparing to undergo gastric bypass or sleeve gastrectomy in Central Norway.
Not a fit: Patients who have previously undergone resections in the gastrointestinal tract may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could improve medication management for patients undergoing bariatric surgery, ensuring effective treatment for depression and anxiety.
How similar studies have performed: While there is limited research on this specific topic, similar studies have shown that surgical alterations to the gastrointestinal tract can significantly impact drug pharmacokinetics.
