Evaluation of the in-vitro antifungal activity of Holoptelea Integrifolia ethanolic extract loaded in microemulsion

Abstract

Microemulsions improve the transdermal delivery of several drugs over conventional topical preparations such as emulsions and gels: enhanced drug solubilization, increased skin flux, and decreased diffusion coefficient. Microemulsion-based systems find significant improvement in the topical delivery of antifungals. We believe that drug-loaded microemulsion will show better antifungal activity by better penetration into the skin and fungal cells. Antifungal agents are mostly lipophilic and easily formulated in topical vehicles. Microemulsions were prepared by the phase titration method. Formulations of the same drug and Excipient ratio and different concentrations were optimized with selected parameters like pseudo ternary phase diagram, particle analysis size, zeta potential validation, entrapment efficiency, and drug release studies performed by dialysis bag diffusion techniques at a temperature (37ºC). The study continued for 24 hours. The maximum amount of drug Holoptelea integrifolia release is 90% within 8hr. The study was monitored at 37ºC. Successfully done preparation, characterization, and drug release study of Microemulsion drug loaded.
