Abstract:
Neuropathic pain (NP) is a chronic ailment due to somatosensory system dysfunction, affecting 7–8% of the global population. Conventional oral anticonvulsants like gabapentin, pregabalin, and carbamazepine exhibit limitations, including poor bioavailability, systemic side effects, and patient non-compliance. Nanoemulsion-based transdermal delivery systems offer a novel approach to overcoming these challenges by enhancing drug solubility, stability, and skin penetration. These isotropic colloidal systems, with droplet sizes of 20–200 nm, incorporate oils, surfactants, and cosurfactants to bypass the gastrointestinal tract, reduce first-pass metabolism, and achieve sustained drug release. Formulation techniques such as ultrasonication, microfluidization, and spontaneous emulsification ensure stable and uniform nanoemulsions for efficient transdermal drug delivery. This strategy addresses the limitations of oral administration while minimizing systemic side effects, improving patient compliance, and enabling localized pain relief. Despite these advantages, challenges persist, including stability issues, scalability, and regulatory hurdles. Future innovations, such as smart nanoemulsions, personalized medicine approaches, and green formulations, are poised to transform chronic pain management and enhance therapeutic outcomes.
