Trial of Analgesia With Lidocaine or Extended-release Oxycodone for Neuropathic Pain Treatment in Multiple Sclerosis

Stopped early · Phase 4 · Has a placebo group

Conditions studied: Neuropathic Pain, Chronic Pain, Multiple Sclerosis

In brief

This study will determine whether treatment with an extended-release opioid or topical lidocaine is effective in relieving distal symmetric lower extremity burning pain associated with multiple sclerosis (MS). If treatment with topical lidocaine is efficacious, it will have important implications for understanding this chronic pain syndrome, which is widely assumed to be caused by central nervous system pathology.
