ABSTRACT

The objective of the present study is to prepare microspeheres of Andrographolide and investigate the physiochemical characteristics of the prepare microspheres. The microspheres of Andrographolide with chitosan were formulated using solvent evaporation method. Formulation variables were optimized to prepare microspheres of Andrographolide such as polymer concentration and stabilizer concentration. The effects of these variables on the particle size and entrapment efficiency were studied. The physiochemical characteristics of microspheres were studied applying particles size analysis, zeta potential and Scanning Electron Microscopy analysis. All the prepared formulation resulted in desire size and relative spherical morphology. The zeta potential was remaining in the range of negative value. It represented an index of particle stability. The in vivo toxicity study in Swiss albino mice were carried out, it shown no significant change in biochemical and haematological examination. Hence the designed system could be safe and it will improve the patient compliance.

Keywords: microspeheres, solvent evaporation, zeta potential, particles size analysis.
