Microneedles comprising hormone-containing surface-modified microspheres and method of preparing the same

Abstract

Microneedles comprising hormone-containing surface-modified microspheres which exhibit improved residence time in the body and superior sustained-release effect, and a method of preparing the same, are disclosed herein. Microneedles including surface-modified microspheres containing a hormone according to the present invention exhibit improved residence time in the body and superior sustained-release effect, and are therefore useful for a transdermal delivery system for delivering a hormone requiring continuous administration.
