Abstract
The main aim of the study was to optimization and evaluation of a suitable dosage form i.e., tropical gel containing silver and gold nanoparticles which are synthesized by green synthesis as this is the rapid and better alternative to chemical synthesis. For burn injury systemic route of administration is not suitable due to damaged skin hence tropical route selected to provide controlled effects, low systemic toxicity and easy application. Silver nanoparticles were synthesized by green synthesis by use of neem leaves and gold nanoparticles by Aloe vera. Characterization was done by UV spectroscopy, particle size distribution, TEM and zeta potential. Gel was formulated by simple mixing and stirring method and evaluated for color, homogeneity, Spreadability, viscosity, in vitro release, antimicrobial study and in vivo study. In this study, the combination of Carbopol 934 P and HPMC (ratio 1:3) was found to be ideal formulation (Formulation F5) with optimum viscosity and Spread-ability i.e., 4459 cP and 5.7 gmcm/sec resp. in vitro release was found to be 98.66% in 12 hours. in vitro antimicrobial study and in vivo study on rat showed maximum effects than standard formulations. From this study it can be concluded that, tropical gel is the superior dosage form containing silver and gold nanoparticles which acts as the antimicrobial agents and is effective in treatment of burn surgery.
