The present invention relates to a sustained-release
enteric coating pellet and a method for manufacturing same and, more specifically, to a sustained-release
enteric coating pellet and a method for manufacturing same, the sustained-release
enteric coating pallet comprising: an
inert core; a
coating layer of an
active ingredient formed on the core; a sustained-release
coating layer formed on the
coating layer of the
active ingredient; and an enteric coating layer formed on the sustained-release coating layer, wherein: the
active ingredient is
tamsulosin or a pharmaceutically acceptable salt thereof; the sustained-release coating layer comprises a sustained-
release agent and a coating stabilizer; the coating stabilizer is
polyvinyl alcohol, such that the pellet allows for the sustained release in a continuous and stable manner under enteric conditions and exhibits high reproducibility even when manufactured under various environmental or
process conditions.
