Bariatric Surgery and Pharmacokinetics of Valsartan

This study examines how bariatric surgery — specifically gastric bypass or sleeve gastrectomy — affects the way the body absorbs the blood pressure medication valsartan. Surgery changes the digestive system in ways that can alter how medications are processed, and this study aims to understand those changes to improve medication management after surgery. Norwegian citizens who are scheduled to undergo gastric bypass or sleeve gastrectomy in Central Norway may be eligible, while those who have previously had surgery on their gastrointestinal tract are excluded. Participation involves taking valsartan and providing blood samples before and after surgery to measure how the drug is absorbed and processed by the body. This summary was generated with AI assistance to help patients understand the study in plain language.
