I had studied development aspects of sustained release microspheres of Diclofenac sodium that release the drug Up to 24 hour and improve Bioavailability of Diclofenac Sodium by using spray drying and simple solvent evaporation technique.Preparation of Chitosan Microsphere with Diclofenac Sodium by various techniques such as spray drying and simple solvent evaporation technique. For Spry Drying technique the optimization of Spry Dried Parameter such as inlet Temperature and Feed pump Rate. Optimization of Temperature by taking the 130 degree C, as a starting Temperature and showing the...
