Fentanyl Nasal Spray Placebo clinical trials

A randomized, parallel group, multi-center study of a fentanyl nasal spray compared with placebo nasal spray for postoperative pain management and prolonged open treatment over up to 120 hours postoperatively compared with intravenous patient-controlled analgesia using morphine

This study compares a fentanyl nasal spray with usual morphine treatment for pain after surgery. It aims to see if the nasal spray is better at controlling pain and how easy it is to use. It's a key step before this spray could potentially be used more widely.
