    摘要: An oral pharmaceutical preparation of a type released at infragastrointestinal tract was successfully prepared, wherein a solid organic acid dissolvable, in the form of a solution, of chitosan and a solid pharmaceutical preparation including a principal agent are filled in a hard capsule composed of the base principally comprising chitosan and an enteric coating is formed on the surface of the hard capsule, characterized in that a desirable releasing time can be arranged, with no pH dependency, via water permeability derived from the porosity of chitosan of the capsule preparation.
