Neuropathic pain - the case for opioid therapy

Area of Science:

• Neurology
• Pain Management
• Pharmacology

Background:

• Neuropathic pain (NeP) presents significant challenges in patient quality of life and is historically difficult to manage.
• Limited understanding of NeP pathophysiology previously led to reliance on non-analgesic drugs.
• Traditional treatment approaches for NeP are evolving with increased understanding.

Purpose of the Study:

• To re-evaluate the role of opioid therapy in managing neuropathic pain.
• To discuss the established efficacy of opioids as second- or third-line treatments for NeP.
• To highlight the potential for undertreatment of NeP due to historical inertia regarding opioid use.

Main Methods:

• Review of current understanding of NeP pathophysiology.
• Analysis of the evolving role of pharmacotherapy in NeP management.
• Re-evaluation of traditional treatment guidelines for NeP.

Main Results:

• Greater understanding of NeP pathophysiology supports more appropriate and often polypharmacy-based therapies.
• Opioids are now established as effective second- or third-line treatments for NeP.
• Opioid therapy is a viable and established option for patients with NeP, potentially improving undertreated cases.

Conclusions:

• The case for opioid therapy in neuropathic pain management is firmly established.
• Opioids complement, but do not replace, first-line therapies like tricyclic antidepressants and anti-epileptic drugs for NeP.
• Optimized NeP treatment involves a comprehensive approach, including the judicious use of opioids when indicated.
