Preparation of Luliconazole loaded silver nanoparticles Topical gel

Abstract

After optimization of the luliconazole loaded silver nanoparticles formulation it was given a gel base for topical delivery the silver nanoparticles have a very low viscosity. The gel was formed by varying the concentration of carbopol 940 as 0.75%, 1. %, 2%. The optimized luliconazole loaded silver nanoparticles formulation LSN14 was incorporated into different concentration carbopol gel base of different concentrations of carbopol and evaluated for various in vitro characterization parameters homogeneity, grittiness, measurement of pH, drug content, viscosity study, Spreadibility, in - vitro drug release studies and drug release kinetics. All prepared gel formulation having different concentration of carbopol was homogenous and uniform in appearance and free from grittiness except the formulation LSN14G1Have not sufficient thickness and thus it was not used further evaluation. On the basis of result of above parameters LSN14G3 was selected for further in-vitro drug release study. Comparison of In vitro Percentage drug release study of Control gel of Luliconazole and luliconazole loaded silver nanoparticle gel formulations LSN14G3 and in - vitro drug release profile the Percentage drug release of prepared silver nanoparticle gel was found to be higher in sustained manner93.36±0.56 after 24 hr as compare to control gel 38.50±1.21.
