New painkiller may cut side effects after hip surgery
NCT ID NCT01536301
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a pain medicine called oxycodone causes fewer side effects than morphine after hip replacement surgery. About 246 adults took part. The goal was to see if oxycodone reduces problems like nausea, vomiting, itching, and breathing trouble by half. The results help doctors choose safer pain relief for patients.
