Effect of Processing Factors on the Properties of Sustained Release Amoxicillin EthylCellulose Microcapsules Prepared by Emulsion Solvent-Evaporation

摘要

We studied the effect of addition of suspension tooil versus oil into suspension, volume of continuousphase versus volume of dispersion phase, dimensionand position of mixing vessel and paddle, stirringspeed and evaporation temperature on the drugrelease and particulate properties of sustained releaseamoxicillin microcapsules prepared by emulsionsolvent-evaporation.
