Fluconazole Emulgels for Onychomycosis Therapy

Pharmacy

Onychomycosis represents a highly prevalent fungal infection of the nail unit that remains difficult to cure. Topical drug delivery offers a promising approach to improve outcomes by directly targeting the site of infection, but efficacy is limited by poor nail penetration. Advanced topical vehicles such as Emulgels can enhance delivery of antifungals across the nail plate. This article reviews the rationale, formulation strategies, and clinical potential of fluconazole Emulgels to treat onychomycosis. Emulsified gel vehicles can increase solubility and nail permeation of hydrophobic antifungals like fluconazole compared to conventional topical formulations. Preformulation studies, optimization of oil phases, polymeric emulsifiers, permeation enhancers and evaluation of critical quality attributes are systematically elucidated. The mechanisms of nail transport and fungal inhibition are also analysed. Fluconazole Emulgels demonstrate favourable physicochemical properties, drug release kinetics, and nail penetration ability in preclinical studies. Clinical investigations reveal therapeutic effectiveness comparable or superior to oral fluconazole with reduced systemic exposure. The improved localization of therapy directly at nail bed and plate is advantageous to eradicate pathogenic dermatophytes and yeasts while avoiding adverse effects and drug interactions with oral treatment. Overall, the research suggests fluconazole Emulgels present a promising topical alternative for improved onychomycosis management
