摘要：The present invention provides a controlled release composition showingrelease of an active ingredient (proton pump inhibitor) controlled in two or more steps atdifferent release rates, which contains 1) a release-controlled part A capable of

controlling release of the active ingredient to occur at a predetermined rate, 2) a release-controlled part B capable of controlling release of the active ingredient to occur at apredetermined rate lower than the release rate of the release-controlled part A, andwhere necessary, 3) a release-controlled part C capable of controlling release of theactive ingredient to occur at a predetermined rate faster than the release rate of therelease-controlled part B, wherein the release of the active ingredient from the release-controlled part B precedes the release of the active ingredient from the release-controlled part A (when release-controlled part C is contained, the release of the activeingredient from the release-controlled part C precedes the release of the activeingredient from the release-controlled part B).
