ABSTRACT
The objective of this investigation was to develop a microsphere and
also attempts were made to control the release of silymarin. Multipleunit
of silymarin microspheres was prepared from Ethyl cellulose and
EudragitRS100 polymer by using emulsion solvent evaporation
method and Ionic cross linking technique.. These microspheres were
evaluated for Drug entrapment, Drug loading, Percentage yield
Swelling index, scanning electron microscopy and in vitro drug
release. All formulations were shows total drug release duration more
than 12 hours. It was observed that the result of in-vitro dissolution
studies reveals that the formulation ED3 & ES3 gave controlled release
pattern.
Keywords: Silymarin, Cellulose microspheres, Eudragit Microspheres, emulsion solvent evaporation method, Ionic cross linking tecninique.
