Summary

This study tests a medicine called Z-338 in children aged 9 to 17 who have functional dyspepsia, a condition causing stomach pain and fullness after eating. The trial has two parts: first checking how the drug moves through the body, then comparing it to a placebo over 28 days to see if it eases symptoms. All participants then receive the drug for another 28 days. The goal is to find a safe and effective treatment for this common childhood digestive issue.
