Summary

This study tests suzetrigine, a new FDA-approved non-opioid pain medication, in 210 adults undergoing total hip replacement. Participants receive either suzetrigine or a placebo for seven days, starting before surgery. The goal is to see if suzetrigine reduces the amount of opioids needed in the first 48 hours after surgery, potentially improving recovery and lowering risks like addiction.

What this could mean

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

Active substance
suzetrigine
What this could lead to
If it works, this could offer a safer, non-addictive painkiller for hip replacement recovery, reducing reliance on opioids.
What could go wrong
This is a Phase 3 trial, but it's still early to know if suzetrigine works better than placebo for this specific surgery. The drug may not significantly reduce opioid use or pain.
