摘要
Lyotropic liquid crystal is an ordered system with various geometric shapes or three-dimensional structures formed by the interaction of amphiphilic molecules dissolved in polar solvents, and has the characteristics of excellent drug applicability, high drug loading, good bioadhesive property and high transdermal permeability. Through a comprehensive analysis of the research results in this research group and the related research reports of LLC drug delivery system, the authors systematically discussed the research value, development potential and research status of LLC in the field of new drug delivery system of traditional Chinese medicine(TCM), especially in the percutaneous and mucosal drug delivery system and the oral microparticle drug delivery system of TCM. At the same time, due to the current research field of TCM-LLC drug delivery system starts late, many of the basic research problems to be further perfect, this paper had carried on the induction summary to these problems, and put forward the research countermeasures:①the basic research of TCM-LLC drug delivery system should be strengthened by referencing the research experience and methods of LLC drug delivery system of single chemical component combined with TCM characteristics, ②the research on the release mechanism of the chemical components in TCM should be strengthened, and the basic research on the LLC drug delivery system of synchronized sustained release TCM should be carried out, ③development of new LLC materials applicable to TCM, ④the quality evaluation system of TCM-LLC should be improved, ⑤to explore the LLC preparation process suitable for industrialization.
