New hope for kids with upset stomachs: drug trial targets painful fullness and bloating

This study tests an experimental medicine called Z-338 in children aged 9 to 17 who have functional dyspepsia, a condition causing stomach pain, fullness, and bloating after eating. The trial has two parts: first, a single dose to check how the drug moves through the body; second, a 28-day treatment period where some children get the drug and some get a placebo. The goal is to see if Z-338 safely reduces symptoms like feeling too full or bloated.
