Abstract

This paper explores the potential of voltage-gated sodium channels, specifically Nav1.7, Nav1.8, and Nav1.9, in the management of neuropathic pain. Neuropathic pain, a complex and chronic condition resistant to conventional treatments, poses a significant clinical challenge. Recent research has shed light on the role of these sodium channel isoforms, predominantly found in peripheral sensory neurons, as novel targets for analgesic development. In this study, we delve into the structural and functional aspects of these channels, their involvement in action potential generation and propagation, and their contribution to neuropathic pain. Furthermore, we review the development and clinical efficacy of selective sodium channel inhibitors, addressing associated challenges and discussing potential future directions in this promising field. Our paper aims to emphasize the potential of sodium channel blockers as a promising approach to neuropathic pain treatment, highlighting their role in providing targeted pain relief with potentially fewer side effects. The contributions of this study include new insights into the role of specific sodium channel isoforms, the evaluation of selective inhibitors, and an overview of the challenges and opportunities in this field of pain managemen.
