Abstract:

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.
