Can patients safely dispense their own pain medicine after surgery?
NCT ID NCT07765238
First seen Aug 14, 2026 · Last updated Aug 14, 2026
Summary
This trial tests a new device that lets patients give themselves liquid acetaminophen (a pain reliever) after total shoulder replacement surgery, instead of waiting for a nurse. The device only releases a dose when it is safe and allowed. The study will see if patients and nurses like using it, and whether it affects pain medicine use and satisfaction.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Patient-Controlled Dispenser and Deactivator (PCDD) Generation 1 system, a device that lets patients self-administer prescribed liquid acetaminophen within a dosing window.
- What this could lead to
- If successful, this device could offer a more convenient and satisfying way for patients to manage pain after surgery, potentially reducing reliance on nurses and opioids.
- What could go wrong
- This is a small pilot study, so results may not be conclusive. The device may be difficult for some patients to use, and satisfaction or pain outcomes might not improve compared to standard care.
