Preparation and Performance Testing of Chitosan-Ibuprofen Sustained Release Microspheres
The chitosan-ibuprofen sustained release mcrospheres have been prepared by the emulsion cross-linked method, and the samples are characterized by EMS(electron microscope) and vitro.UV spectrophotometer. Research results indicate that the concentrations of IBF in solution are different with the different pH conditions. The quantities of cross linking agent, the mass ratio and temperature are selected to optimize on the MIC’s size and morphology.
