Summary

This study tests whether giving a single intravenous dose of methadone during hip replacement surgery reduces pain and the need for extra opioids right after the operation. Researchers will compare pain scores and opioid use in 162 adults receiving either methadone or a placebo. The goal is to see if this simple addition improves recovery and lowers opioid consumption.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
methadone
What this could lead to
If it works, this could offer a simple way to better manage pain after hip replacement and reduce the need for other opioids.
What could go wrong
This is a single-center trial with 162 people, so results may not apply broadly. Methadone can cause side effects like nausea or breathing problems.
