采用中心复合设计优化了影响多孔型核壳复合颗粒(PCPs)直接压片(DC)性能的配方参数.分别以PVP和NH4HCO3作为壳层材料和制孔剂,选择共喷雾干燥为制备工艺.以PCPs的产率、流动性、压缩性和崩解时间作为响应值.结果表明,NH4HCO3和PVP K30的最佳配比分别为4.76％和9.42％.产率、流动性、压缩性和崩解时间的测定值分别为62.00％、38.50°、4.02 MPa和14.33 min.预测误差分别为2.99％、1.09％、5.70％和2.28％.在本研究中,最优的PCPs与四种DC辅料混合用于连续DC.结果表明,优化后的PCPs具有优良的直压性能和适用性,为其他中药制备PCPs及实现DC提供思路和理论支持.
Optimization and application of porous core-shell particles for direct compaction
Xiao Er Xi Shi formulation powder(XEXS)is often used to treat indigestion for children and its extract powders have poor functional properties.In order to prepare XEXS-PCPs(porous core-shell composite particles)with optimal properties,the central composite design was used to optimize the formulation parameters that affect the direct compaction(DC)properties of PCPs based on XEXS.The proportions of shell material and pore-forming agent were taken as independent variables,and the yield,flowability,compactibility and disintegration time of PCPs were used as the response values.It was found that the best proportions of NH4HCO3 and PVP K30 were 4.76％and 9.42％,respectively.Furthermore,the measured values of yield,flowability,compactibility and disintegration time were 62.00％,38.50°,4.02 MPa and 14.33 min,respectively.The prediction errors were 2.99％,1.09％,5.70％and 2.28％,respectively.In the present study,the optimal PCPs were mixed with four DC-grade excipients for continuous DC.The results showed that the optimal PCPs had excellent DC properties and applicability.It provides ideas and theoretical support for preparing PCPs and realizing DC for other traditional Chinese medicine.
