What this trial studies
This observational study investigates how bariatric surgery, specifically gastric bypass and sleeve gastrectomy, affects the pharmacokinetics of losartan, 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 losartan. The study will involve patients preparing for these surgical procedures in Central Norway, focusing on how their altered gastrointestinal physiology may impact medication absorption and effectiveness.
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 treatment for hypertension.
How similar studies have performed: While there is limited research on this specific interaction, similar studies have shown that bariatric surgery can significantly alter drug pharmacokinetics, suggesting potential for meaningful findings.
