[摘要]目的分析2016—2020年世界范围内固体分散体研究热点及前沿,为固体分散体领域的研究提供参考。方法使用 Web ofScience(WOS)数据库检索2016—2020年固体分散体相关文献,使用 Cite Space 5.7.R2软件进行文献计量分析。结果该领域发文量先呈上升趋势而后趋于平稳,科研机构之间合作较少,且多集中在国内合作,跨国交流较少。当前的研究热点是固体分散体的稳定性、药物释放和载体材料等方面。当前的研究前沿为固体分散体的渗透性、稳定性、热熔挤出法等方面。结论目前固体分散体研究较为充分,已形成多学科合作的学术研究关系,中国在固体分散体研究中处于世界领先水平。

[Abstract] Objective To analyze the research hotspots and frontiers of solid dispersions worldwide from 2016 to 2020, and to provide references for the research in the field of solid dispersions. Methods The Web of Science (WOS) database was used to retrieve the literature on solid dispersions from 2016 to 2020, and the Cite Space 5.7.R2 software was utilized for bibliometric analysis. Results The number of publications in this field first showed an upward trend and then tended to stabilize. There was less cooperation between scientific research institutions, which was mostly domestic cooperation with less cross-border exchanges. Current research hotspots were the stability of solid dispersions, drug release and vehicle materials. Current research frontiers focused on the permeability, stability, and hot melt extrusion of solid dispersions. Conclusion At present, solid dispersion research is relatively broad, and a multidisciplinary cooperative academic research relationship has been formed. China is at the world's leading level in solid dispersion research.

藥物的溶解性是控制其在体内吸收、分布、代谢、排泄等药代动力学过程的重要理化性质之一。药物溶解性差、溶出度低会直接影响其疗效[1]。因此,改善药物的溶出和吸收,提高其生物利用度已成为制剂研究的一项重要问题。固体分散体是指将药物以分子、胶体、微晶或无定形状态高度分散在载体材料中形成的一种固体分散物[2]。固体分散体由于其较高的溶出速率及有效改善难溶性药物生物利用度的能力而受到广泛关注[3-4]。Cite space 是陈超美教授研发的一款具有文献可视化功能的软件,可以在大量文献中提取出文献对应领域的热点和前沿,并进行直观的图谱分析[5]。WOS 数据库收录了各大领域的优秀文章,文献覆盖面广泛[6]。……
