Testing oxytocin and vibration effects on pain from sunburn

A Randomized Controlled Trial to Test Whether Oxytocin Amplifies the Effect of Vibration to Increase Heat Pain Threshold After UV-B Burn

Phase 2 Interventional Wake Forest University Health Sciences · NCT06651476

This study is testing if a hormone called oxytocin, combined with vibration therapy, can help people with mild sunburn feel less pain.

What this trial studies

This clinical trial investigates whether intravenous oxytocin can enhance the pain threshold in individuals experiencing mild sunburn when combined with vibration therapy. Participants will be randomly assigned to receive either oxytocin or a placebo, and their pain responses will be measured after exposure to UV-B light. The study aims to determine if oxytocin, a naturally occurring hormone, can provide additional analgesic benefits in this context. The trial will include healthy volunteers aged 18 to 55 with specific skin types and health criteria.

Who should consider this trial

Good fit: Ideal candidates are healthy adults aged 18 to 55 with a Fitzpatrick skin type rating of I to III.

Not a fit: Patients with darker skin types, chronic pain conditions, or a history of certain cardiovascular issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new method for managing pain associated with sunburn.

How similar studies have performed: While the combination of oxytocin and vibration therapy is a novel approach, similar studies have shown promise in pain management, suggesting potential for success.
