Effectiveness of Controlled-Release Morphine for Chronic Neuropathic Pain After Spinal Cord Injury

Completed · Phase 2 · Has a placebo group

Conditions studied: Neuropathic Pain, Spinal Cord Injury

In brief

We would like to learn if a medicine called "modified-release morphine sulfate" (Avinza) helps reduce Spinal Cord Injury (SCI)-related pain that has lasted a long time. "Modified-release" means that the medicine in the capsules is slowly released to the body, instead of being released all at once. Avinza is approved by the Food and Drug Administration for the treatment of pain, but we do not know how effective Avinza is in reducing SCI-related pain.
