Opioid-Induced Hyperalgesia and Inflammaging in the Management of Spine Pain: The Case for Genetically Directed Dopamine Homeostasis.

Abstract

Background: The management of spine-related pain with narcotics, both before and after surgery, poses major challenges, including drug diversion, limited effectiveness, and worsening of pain symptoms over time. Chronic opioid use is associated with hypodopaminergia-induced hyperalgesia, whereby dopamine depletion increases pain sensitivity. Patients with inherently low dopaminergic function are particularly predisposed to hyperalgesia and reduced pain tolerance.

Methods: An alternative therapeutic strategy centers on genetically guided pro-dopamine regulation, which aims to transmodulate dopaminergic signaling to mitigate hyperalgesia. Early identification of predisposition through genetic testing, combined with pharmacogenetic and pharmacogenomic monitoring, is proposed to optimize treatment approaches.

Results: Pro-dopamine regulators have demonstrated promising results across 43 clinical studies, showing potential to reduce stress, craving, and relapse rates, while improving emotional well-being and attenuating pain sensitivity. These findings suggest that pro-dopamine regulation may serve as a viable frontline therapy for managing chronic pain and associated Reward Deficiency Syndrome behaviors, offering a significant reduction in the adverse effects commonly observed with chronic opioid therapy.

Conclusions: Given the limitations of dopaminergic blockade through chronic opioid agonist therapy, there is a critical need to reevaluate current pain management practices. The induction of dopamine homeostasis via pro-dopamine regulation represents a novel and potentially transformative strategy. Spine surgeons, pain specialists, and addiction medicine practitioners are urged to consider this approach as a promising alternative for improving long-term outcomes in patients suffering from chronic pain.
