RESUMO
@#Liposome injection is one of the most successful special injections that use nanotechnology to enhance drug efficacy and reduce accompanied toxicity. New liposomes with special structures and functions have emerged since the first liposome injection containing doxorubicin was marketed. This review summarized the principles and research progress of Stealth liposome technology and cationic liposome technology, analyzed the structural and functional characteristics and clinical application advantages of liposome products that have been marketed from the perspective of pharmacology, introduced current research hotspots of new liposomes, and analyzed the current regulatory status of liposome injection at home and abroad, thereby providing theoretical reference for the research and development（R&D）, clinical translation and supervision of liposome injection.
