Domestic technology review of microneedle patents

Abstract

Microneedle is a new type of drug delivery technology, which forms tiny pores on the surface of the skin through a special needle-like structure to break through the skin barrier and deliver drugs to the body with high efficiency, thus promoting drug penetration and absorption, which plays an important role in drug delivery. In recent years, with the continuous development of microneedle technology, the application field of microneedles has become more and more extensive, and the research of microneedles has become the hot spot of research and development today. This article has conducted a statistical analysis of the application trend, applicant's source, legal status, technical application and preparation process of patent applications in this field, and focused on summarizing the technical application of domestic microneedle patents in the field of pharmaceutical technology, medical beauty and several mainstream preparation processes. The statistical analysis was also conducted to summarise the technical applications of domestic microneedle patents in the fields of pharmaceutical technology and medical aesthetics and several mainstream preparation processes.
