Obesity Clinical Trial
Official title:
The Bioavailability and Effect on Pouch pH of Esomeprazole as Tablets or in Solution After Laparoscopic Proximal RYGB for Morbid Obesity - an Investigator Blinded Pilot Study
The objective of this study is to investigate the effect of Esomeprazol administered in tablets (Esomeprazol MUT Sandoz® 40mg) or in solution (Esomeprazol MUT Sandoz® 40mg in 10ml tap water) on acid production in the gastric pouch by measuring the intragastric pH and the serum concentration of esomeprazole.
To assess the clinical effect of the esomeprazole absorption after Roux-en-Y gastric bypass, we intend to measure the serum concentration after administration as intact capsules or open in solution and correlate it with the pH in the gastric pouch, measured with the wireless BRAVOTM capsule pH measurement system. The feasibility and safety of the wireless pH monitoring system has been shown before. The patients who met all the inclusion criteria undergo a routine upper endoscopy one year after RYGB. At the end of the endoscopy, the wireless BRAVO™ - pH monitoring device is placed and the participant is discharged with ongoing pH monitoring. The next day, the participant is randomized to either receive Esomeprazol MUT Sandoz® tablet 40mg or Esomeprazol MUT Sandoz® 40mg in solution. Serum concentration of Esomeprazol is measured at 0, 60 and 120 minutes and the patient is discharged after. After 48 hours of pH monitoring, the patient returns the BRAVO™ - recorder, adverse events are assessed and the study is terminated. ;
