Abstract
The present invention relates to an oral pharmaceutical composition in particle form, which comprises particles that contain a drug at the core of the pharmaceutical composition in particle form; a middle layer that contains two types of water-soluble components, an insolubilizer and an insolubilizing substance; and an outer layer for controlling water penetration that contains a water-insoluble substance. The present invention makes it possible to provide a pharmaceutical composition in particle form for oral use with which initial drug release is suppressed, the drug is quickly released thereafter, and lag time can be controlled as needed, and fast-disintegrating tablets containing this composition.
