The present invention provides a controlled release composition showing release of an active ingredient (proton pump inhibitor) controlled in two or more steps at different 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 a predetermined rate lower than the release rate of the release-controlled part A, and where necessary, 3) a release-controlled part C capable of controlling release of the active ingredient to occur at a predetermined rate faster than the release rate of the release-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 active ingredient from the release-controlled part C precedes the release of the active ingredient from the release-controlled part B).
本发明提供了一种控释组合物,其活性成分(质子泵抑制剂)的释放可通过两个或多个步骤以不同的释放速率进行控制,该组合物包含
1) 能够控制活性成分以预定速率释放的释放控制部分 A、
2) 能控制活性成分以低于释放控制部分 A 的释放速率的预定速率释放的释放控制部分 B,必要时, 3) 能控制活性成分以快于释放控制部分 B 的释放速率的预定速率释放的释放控制部分 C、其中,活性成分从释放控制部分 B 的释放先于活性成分从释放控制部分 A 的释放(当包含释放控制部分 C 时,活性成分从释放控制部分 C 的释放先于活性成分从释放控制部分 B 的释放)。
