Background: Skin, the largest organ of the human body, frequently encounters infections, with superficial fungal infections being among the most common globally. Conventional topical antifungal therapies often suffer from limitations such as inadequate skin penetration and systemic side effects. There is a need for improved delivery systems that enhance efficacy and patient compliance. Objective: To formulate and evaluate a fluconazole-loaded nano-emulgel with improved penetration, sustained drug release, and enhanced antifungal efficacy for topical application. Materials and Methods: Fluconazole was incorporated into a nano-emulgel system prepared using Carbopol 940, hydroxypropyl methylcellulose, sunflower oil, cinnamon oil, and PEG-400. The formulations were subjected to pre-formulation, post-formulation, and stability studies, including UV-Vis, FTIR, particle size, zeta potential, encapsulation efficiency, drug release, and physicochemical evaluation. Results: Formulation F3 showed optimal performance with superior encapsulation efficiency and sustained drug release. All formulations demonstrated nanoscale dispersion, good stability, acceptable viscosity, spreadability, and skin-compatible pH, indicating suitability for topical antifungal application. conclusion: The fluconazole-loaded nano-emulgel demonstrated promising characteristics for topical antifungal therapy, with enhanced drug retention, stability, and sustained release. Among the formulations, F3 showed optimal performance, indicating potential for clinical application in treating superficial fungal infections Discussion: The findings highlight the potential of nano-emulgels to address major limitations of conventional fluconazole formulations by enhancing solubility, penetration, and retention at the site of infection. The synergistic role of natural oils provided additional antimicrobial and antioxidant benefits, further supporting the therapeutic efficacy. Compared to traditional gels and creams, the developed system offers controlled release and prolonged activity, which may improve treatment outcomes and patient adherence. These results position fluconazole-loaded nano-emulgels as a promising alternative for the management of superficial fungal infections, aligning with the global need for more effective and patient-friendly antifungal therapies. Conclusion: The fluconazole-loaded nano-emulgel demonstrated promising characteristics for topical antifungal therapy, with enhanced drug retention, stability, and sustained release. Among the formulations, F3 showed optimal performance, indicating potential for clinical application in treating superficial fungal infections.
