What this research studies

Many people experience pain, and while opioid medications can help, their misuse is a serious concern. We know that men and women often misuse opioids in different ways, with men showing higher rates of increasing their doses and experiencing overdose. This project uses laboratory models to understand how pain and past opioid use might lead to these sex-specific differences in opioid misuse. By uncovering these underlying reasons, we hope to find better ways to manage pain and prevent opioid addiction.

Who could benefit from this research

Good fit: This research is relevant to adult patients, aged 21 and older, who experience chronic pain and are concerned about or have a history of opioid use.

Not a fit: Patients who do not experience pain or use opioid medications would not directly benefit from this specific research.

Why it matters

Potential benefit: If successful, this work could lead to more personalized and effective pain management strategies that consider individual differences between men and women, potentially reducing opioid misuse.

How similar studies have performed: Preliminary findings from this research team have shown similar sex-dependent trends in laboratory models as observed in human clinical data, suggesting a promising direction for this work.
