摘要： An orally-administered agent according to the present invention comprises: a medicine-containing layer containing a medicine and having surfaces; collapse-controlling layers respectively provided on the surfaces of the medicine-containing layer; and gel-forming layers respectively provided on the collapse-controlling layers, wherein the gel-forming layers are swelled and gelatinized by absorbing water to form a gel. The collapse-controlling layers are constituted of a material containing a stomach-soluble material to be dissolved by being in contact with gastric juice. The orally-administered agent according to the present invention can be swallowed with ease and release the medicine in intended parts, in particular, the stomach of a living body.

摘要： An orally-administered agent is provided. The orally-administered agent comprises an intestinal medicine-containing layer containing a medicine to be released in intestines and having surfaces; intestinal collapse-controlling layers provided directly or through an arbitrary layer on the surfaces of the intestinal medicine-containing layer, respectively, at least a part of the intestinal collapse-controlling layers being collapsed in the intestines, and each of the intestinal collapse-controlling layers having a surface opposite to the intestinal medicine-containing layer; and gel-forming layers provided directly or through an arbitrary layer on the sides of the surfaces of the intestinal collapse-controlling layers, respectively, wherein the gel-forming layers are swelled and gelatinized by absorbing water to form a gel. The intestinal collapse-controlling layers are constituted of a material containing an enteric material to be dissolved by being in contact with a body fluid in the intestines. The orally-administered agent according to the present invention can be swallowed with ease and can release a medicine at intended parts of a living body (in particular, within intestines).
