The objective of the present study was todesign and develop topical nanoemulsion based TerbinafineHCl (TBH) gel to increase its permeability and efficacyusing rat as an animal model. Nanoemulsions wereprepared by two different techniques viz. high pressurehomogenization and high speed homogenization, the preparednanoemulsions were incorporated into carbomer gelto obtain nanoemulsion based gel, which designated asGel-P and Gel-S respectively. The developed gels wereevaluated for drug content, stability, spreadability, andin vitro permeation using pork skin. The in vivo antifungalefficacy of the developed gels was assessed in albino Wistarrats. The globule size obtained by high pressurehomogenization was less than 2 nm in radius (r.nm) andthat by high speed homogenization was less than 10 r.nm. In vitro permeation studies revealed that Gel-P(51.19 ± 0.81 %) had higher permeation when comparedto Gel-S (31.72 ± 1.12 %) and marketed cream(19.78 ± 1.01 %) which is essential to treat topical fungaldiseases. In vivo antifungal studies in Wistar rats infectedwith Trichophyton mentagrophytes revealed that topicalapplication of Gel-P and Gel-S cured the infection within3 days compared to 14 days for Marketed Cream (M.C). This study confirms that the nanoemulsion gels providedgreater permeation followed by cure rates of poorly solubleTBH in animal model and hence these systems could be thepreferred drug carriers for drugs intended for topical use toovercome the permeability and efficacy problems.
