Predictors of Opioid Analgesic Responses and Common Endogenous Opioid Mechanisms
The overall purpose of this study is to improve our understanding of factors that may influence how much pain relief people get from opioid-based medication, and the potential risks of taking these medications. This study will focus on differences between people in how they respond to brief laboratory pain tasks while taking morphine, while taking a substance that blocks the natural opioid-based pain systems in the human body (naloxone), and while taking a “placebo” (harmless saline [salt] solution).
You may be eligible to participate in this study if you:
- Are healthy and without chronic pain
- Have chronic low back pain
