Testing the Efficacy of Transungual Drug Delivery System (Nail Lacquer) Containing Terbinafine AgainstAspergillus brasiliensisfor the Topical Treatment of Onychomycosis

Abstract

AbstractAccording to a survey of 42 epidemiological studies, the cases of Non-dermatophyte mould onychomycosis (NDMO) caused by Aspergillus species have been found to increase. The number ranges from <1 to 35% of all cases of onychomycosis in the general population and the number is higher in the diabetic population. Around7.7-100% of cases of NDMO are caused by Aspergillus species. Hence the attempt of investigation to test the efficacy of the drug by transungual drug permeation has been made. The antifungal agent ‘Terbinafine’ was incorporated in a topical dosage form (Nail lacquer). The formulation is optimized by a drug design matrix of 23type using Design-Expert®software, version 11 (DX11). The antifungal assay was performed using the Kirby Bauer disk diffusion method and other evaluation parameters like Drying time, Viscosity are evaluated. Optimized formulation with the highest desirability was selected out of all the possible formulations which showed the best results with good physicochemical properties and antifungal activity. Thus, it can be concluded that medicated nail lacquers containing Terbinafine can be used as a successful method to treat non-dermatophyte mould onychomycosis (NDMO) caused by Aspergillus species.
