Summary
This completed phase 2 trial tested whether oxytocin, given as a nasal spray or through an IV, can reduce pain from heat in healthy adults. Twenty-four participants rated their pain on a 0-10 scale after skin heating. The study also looked at whether age, weight, or sex affect how well oxytocin works.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- oxytocin
- What this could lead to
- If it works, this could point toward a new way to manage acute pain using oxytocin.
- What could go wrong
- This is a small, early-phase trial in healthy volunteers, not patients with chronic pain. The pain is lab-induced, so results may not apply to real-world pain conditions.
