Effects of bariatric surgery on the absorption of amlodipine

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study investigates how bariatric surgery, specifically gastric bypass and sleeve gastrectomy, affects the pharmacokinetics of amlodipine, a medication used to treat high blood pressure. 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 will involve patients preparing for these surgical procedures in Central Norway, focusing on how their surgery impacts medication absorption.
