Abstract
Disclosed is a controlled-release microparticle: including a matrix comprising a pharmacologically active component; and a controlled-release layer comprising a substance which forms a controlled-release stratum on the matrix. The disclosed controlled-release microparticle not only allows effective dual release control of a drug but can also exhibit outstanding dissolution characteristics even when a small amount of coating substance is used.
