Pravallika T.*, Dr. P. Prasuna Sundari, Dr. M. Bhagavan Raju
The aim of this research work is to develop voriconazole Transferosomal gel for better transdermal permeation and to produce sustained release of drug for local antifungal activity. Voriconazole is a triazole antifungal drug. It is used orally and intravenously. Formulation of voriconazole as transferosomal gel reduces dose dumping and increases therapeutic efficacy. Transferosomes are appropriate delivery system for skin. They are ultra-deformable vesicles. Voriconazole transferosomes were prepared by Thin Film Hydration method using Phosphatidylcholine and Edge Activators in different ratios. The edge activators used in the formulation are Span 60, Span 80 and Tween 80. The prepared transferosomes were evaluated for entrapment efficiency, drug content and in vitro drug release. Formulation F3 containing phosphatidylcholine (85mg) and Span 60 (15mg) was selected based on entrapment efficiency and drug release. Entrapment efficiency and drug release was 87.62±0.26 and 82.52±0.35. The selected formulation shows Zeta potential of -57.7mV and vesicle size of 597.4nm. The selected formulation F3 was incorporated into gel using Carbopol 934 of different concentrations. Formulated gels were evaluated for visual appearance, pH, drug content and In vitro diffusion studies. The selected transferosomal gel of voriconazole shows pH value 6.7, drug content 91.56 and drug release percentage 79.54.
