Kids' painkiller mystery: anesthesia may change how oxycodone works
NCT ID NCT03054831
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how general anesthesia changes the way children process liquid oxycodone, a common painkiller used after surgery. Researchers will give the drug to 40 children aged 2-8 at different times during anesthesia and measure its levels in the blood. They will also check if certain genes affect how the drug is broken down. The goal is to understand how to dose oxycodone more safely in kids.
