Abstract:
Due to the complex source and different physical and chemical properties of traditional Chinese medicines(TCM) powder, there are many common pharmaceutical problems in its preparation, such as large particle size difference, poor mixing uniformity, and poor compliance with oral intake, which has directly affected the quality of solid preparations as well as their clinical efficacy and safety. This study observed the property of Zhuhuang Chuihou Powder and extract its pharmaceutical defects. It was found that realgar and calcined Borax in Zhuhuang Chuihou Powder were heavy in texture and toxic, and they were easy to be isolated, indicating the potential safety hazard. At the same time, Coptidis Rhizoma and Phellodendri Chinensis Cortex were the main sources of its bitterness. Therefore, based on the idea of "drug-excipients unity", the particle design technology was used to prepare core/shell-type composite particles with bitter medicines as the core and mineral medicines as shell. Both infrared spectroscopy and scanning electron microscopy results indicated the formation of composite particles, and the taste of these composite particles were improved. Compared with the physical mixtures, the composite particles exhibited significantly decreased RSD values in the content uniformity of berberine hydrochloride, arsenic disulfide, and sodium tetraborate and appearance uniformity. The introduction of particle design technology solved the problem of uneven dispersion of Zhuhuang Chuihou Powder, thus ensuring its uniform dispersion, stability, and control and improving the quality of the original preparation. This has provided a scientific basis for the quality control of TCM powder.
