Opioid Treatment for Chronic Low Back Pain and the Impact of Mood Symptoms

Completed · Phase 4 · Has a placebo group

Conditions studied: Chronic Low Back Pain, Degenerative Disc Disease, Depression, Anxiety

In brief

Opioids are frequently prescribed for chronic low back pain (CLBP). Psychiatric illness, such as high levels of depression and anxiety symptoms, is a common co-occurrence in chronic pain patients (and is termed comorbid negative affect \[NA\]). The purpose of the study is to determine whether CLBP patients with either a high vs. a low or moderate degree of NA have different pain relief responses to oral opioids.

• In men, normal baseline testosterone levels.

You may not qualify if…

• Patients with pain due to disorders not including a component of disc degeneration, or those with unknown causes of pain will be excluded.
• Patients with the intent to undergo back surgery will be excluded.
• Patients with a history of recent or ongoing alcohol or other drug addiction disorders will be excluded.
• Patients with any history of substance abuse of opioids will be excluded.
