Supercritical Fluid Impregnation of Microcrystalline Cellulose Derived from the Agricultural Waste with Ibuprofen
SUSTAINABLE CHEMISTRY AND PHARMACY(2021)
摘要
The present study was aimed to investigate the feasibility of loading microcrystalline cellulose derived from the agricultural waste with poorly water-soluble drug by using supercritical carbon dioxide as impregnation medium. Operating parameters of supercritical impregnation process (pressure, temperature and time) were varied to in order to maximize loading of ibuprofen used as a model drug into microcrystalline cellulose. The efficiency of ibuprofen loading using supercritical impregnation and release kinetics studies of microcrystalline cellulose in two pharmaceutical forms, powder and tablets, were investigated.
