What this trial studies

This study investigates the effects of oxytocin when administered alongside oxycodone to determine if it can lower the abuse potential of the opioid while enhancing pain relief. Participants will self-administer intranasal oxytocin or a placebo shortly after taking oral oxycodone or a placebo in a controlled laboratory setting. The study will involve six sessions where the effects on pain, subjective experiences, and decision-making will be evaluated. The research aims to provide insights into the safety and efficacy of combining these substances in a non-residential, double-blind, randomized format.

Who should consider this trial

Good fit: Ideal candidates are older adults who have previously used opioids but are not currently experiencing chronic pain.

Not a fit: Patients with significant physical diseases, major psychiatric disorders, or those currently interested in drug abuse treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to safer pain management strategies for older adults, reducing the risk of opioid abuse.

How similar studies have performed: While the combination of oxytocin and opioids is a novel approach, preliminary research suggests potential benefits, though this specific methodology has not been extensively tested.
