Impact of Bariatric Surgery on Gabapentin Absorption

Bariatric Surgery and Pharmacokinetics Gabapentin: BAR-MEDS Gabapentin

Observational Norwegian University of Science and Technology · NCT03476538

This study looks at how bariatric surgery affects how well gabapentin, a medication for nerve pain and seizures, is absorbed by patients after their surgery.

What this trial studies

This observational study investigates how bariatric surgery, specifically gastric bypass and sleeve gastrectomy, affects the pharmacokinetics of gabapentin, a medication commonly used for nerve pain and seizures. It aims to understand changes in gastric pH, gastric emptying time, and gastrointestinal transit time that may influence the biological availability of gabapentin post-surgery. The study will involve patients preparing for these surgical procedures in Central Norway, focusing on their medication absorption and effectiveness after surgery.

Who should consider this trial

Good fit: Ideal candidates are Norwegian citizens preparing to undergo gastric bypass or sleeve gastrectomy.

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 lead to improved medication management for patients undergoing bariatric surgery, ensuring effective pain control and seizure management.

How similar studies have performed: While there is limited research on the pharmacokinetics of medications post-bariatric surgery, this study addresses a relatively novel area of investigation.
