在制剂仿制开发的要素中，国内制剂企业的瓶颈是药用辅料的受限，在已正式颁布实施的2020年版《中国药典》四部中，辅料收载品种由2005年的76个增加到了目前的335个，收载品种数量增加了5倍。而制剂的应用才是药用辅料的终极目的，辅料性能的提升也极大有利于制剂质量的保障。近年来，国内涌现出一批技术含量高、规模效益好的优质辅料生产企业，辅料联盟近期会约请这些企业，为大家介绍一下它们与制剂研发相关的一些成果，本周六（2021.12.11）上午九点钟辅料联盟邀请的企业是安徽山河药辅和西安德立生物，请他们分别讲一下微晶纤维素和倍他环糊精及其衍生物等辅料的性能、参数对比，望大家届时收看

       Among the elements of preparation generic development, the bottleneck of domestic preparation enterprises is the limitation of excipients. In the volume IV of the Chinese Pharmacopoeia (2020 edition), the number of excipients has increased from 76 in 2005 to 335 at present, increased for 5 times. The application in preparation is the ultimate purpose of excipients, and the improvement of excipients performance is also beneficial to the guarantee of the quality of preparation. In recent years, a number of high-quality excipients manufacturers with advanced technology and large scale have emerged in China. The Excipients manufacturing quality group will invite these enterprises to introduce some of their achievements related to preparation R&D. At 9:00AM this Saturday (2021.12.11), the enterprises Anhui Sunhere Pharmaceutical Excipients Co., Ltd and Xi'an DELI Biochemical Industry Co., Ltd. will talk about the performance and parameter comparison of microcrystalline cellulose, beta cyclodextrin and its derivatives. Please join in to watch online and discuss.
