Summary
This trial is testing vonoprazan, a drug that reduces stomach acid, in teenagers who have GERD. GERD causes discomfort due to excess stomach acid. Vonoprazan works by blocking pumps in the stomach that produce acid, helping to relieve symptoms like heartburn. Vonoprazan has shown greater ability to suppress gastric acid production compared to conventional treatments.
