No results posted yet for this study

Summary

The purpose of this study is to determine whether exposure to prescription opioids is associated with brain structural changes on magnetic resonance imaging (MRI), with the primary outcome of white matter integrity as measured by fractional anisotropy of the corpus callosum.

Conditions

  • Pain, Chronic

Interventions

DRUG

Opioid

Subjects will receive oral oxycodone as needed for pain which will be titrated weekly based on pain response, adverse effects, and patient preference. Subjects with intolerance to oxycodone will receive the equivalent dosing of morphine as an alternative.

DRUG

Opioid Placebo

Subjects will receive a placebo capsule identical to oxycodone, which will similarly be titrated weekly. Subjects with intolerance to the first placebo will receive another placebo capsule identical to morphine.
