Review on anti-tumour lipid nano drug delivery systems of traditional Chinese medicine.

Abstract

In recent years, the use of traditional Chinese medicine (TCM) in the treatment of cancer has received widespread attention. Treatment of tumours using TCM can effectively reduce the side effects of anti-tumour drugs, meanwhile to improve the treatment efficacy of patients. However, most of the active ingredients in TCM, such as saponins, alkaloids, flavonoids, volatile oils, etc., have defects such as low bioavailability and poor solubility in clinical application, which seriously restrict the application of TCM. Meanwhile, the encapsulation of TCM into lipid nano-delivery systems for cancer therapy has received much attention. Lipid nano-delivery systems are obtained by using phospholipids as the base material and adding other auxiliary materials under a certain preparation process, including, for example, liposomes, solid lipid nanoparticles (SLNs), nanostructured lipid carriers (NLCs), microemulsions, and self-microemulsion drug delivery systems (SMEDDS), can resolve the application problems of TCM by improving the efficacy of active ingredients of TCM and reducing the toxicity of anti-tumour drugs. This paper focuses on the categories, development status, and research progress of lipid nano delivery system of TCM, aiming to provide a certain theoretical basis for further in-depth research and rational application of these systems.
