Acid pill or liquid: which works better after Weight-Loss surgery?

NCT ID NCT05320796

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looks at how the body absorbs esomeprazole (a stomach acid reducer) when taken as a tablet or dissolved in water, in people who had gastric bypass surgery a year ago. Fifty participants will have a small device placed in their stomach pouch to measure acid levels, and blood samples will be taken to check drug levels. The goal is to see which form works better to control acid and prevent ulcers.
