Lidocaine Infusion for Chronic Pain in Opioid Dependent Patients

• Status: Terminated
• Trial end date: 2019-09-20
• Target enrollment: 0
• Participant gender: All

Summary

Prescription drug abuse represents a major healthcare problem, with treatment costs reaching billions of dollars annually in the United States alone. Today opioids are commonly prescribed for chronic non-cancer pain and are only partially effective for short-term pain relief. Whereas opioids are initially part of the solution for pain, it eventually often turns to be a problem in patient with chronic pain. Long-term treatment with opioids can be complicated by development of tolerance, dependency, addiction, abnormal pain sensitivity, hormonal changes, and immune modulation. Unfortunately, the chronic use of anti-inflammatory drugs is associated with a marked increase in adverse effects.

The purpose of this study is to determine whether systemic administration of lidocaine provides effective pain relief in opioid dependent chronic pain patients. Investigators intend to demonstrate that lidocaine infusion can improve pain relief and physical function in opioid dependent patients, thus improving compliance and patient satisfaction, which may potentially help wean patients off narcotics. The long-term goal of this proposal is to decrease opioid dependence in chronic pain patients by using lidocaine infusion.
