High-end preparations are improved and innovative on the basis of traditional preparations, with the primary purpose of overcoming therapeutic defects and achieving clinical advantages. By changing the physical and chemical properties and metabolic characteristics of drugs, the treatment effect can be improved, toxic side effects can be reduced, medication compliance can be improved, clinical needs can be met, and patients can benefit more. Special dosage forms of high-end preparations include liposomes, microspheres, nanoparticles, fat emulsion, micelles, implants, PEgs and many other slow-release and targeted dosage forms, among which microspheres and liposomes are more difficult and have a higher threshold for research and development in the field of preparations, and have become one of the mainstream trends in drug development. Based on the actual case sharing, the forum discussed the research and development strategy direction of innovative preparations under the new situation from the perspective of relevant product development strategies, application of pharmaceutical technology platforms and relevant policy interpretation.
