Biodegradable microneedles applied in the transdermal drug delivery:research advances / 国际药学研究杂志

ABSTRACT

Microneedle is a painless and minimally invasive transdermal drug delivery. It can enhance the permeability of skin for macromolecular drugs by puncturing and creating a micron-level drug delivery channel in the skin. The biodegradable microneedles aim to solve the problem that nondegradable-material microneedles may break under skin and cause adverse reaction. This article pro?vides an overview of the characteristics of biodegradable microneedles,the biodegradable materials used,its recent research progress, the development status and the tendency.
