PROBLEM TO BE SOLVED: To provide an adsorbent for medicine for oral administration which is excellent in the adsorption capacity and selective adsorption of a toxin which should be removed while being small in dose amount, favorable in terms of economy and suppressed in environmental load.SOLUTION: The adsorbent for medicine for oral administration is characterized in that the adsorbent is composed of granular activated carbon which is obtained by carbonizing and activating refined cellulose or regenerated cellulose, and in which an average fine pore diameter is 1.5 to 2.2 nm, a BET-ratio surface area is 700 to 3,000 m2/g, an average particle diameter is 100 to 1,100 &mu；m, a surface oxidation amount is not smaller than 0.05 meq/g, and filling density is 0.4 to 0.8 g/mL, and which is used as an oral administration therapeutic agent or an oral administration prevention agent for a renal disease or a liver disease.COPYRIGHT: (C)2012,JPO&INPIT【課題】少ない服用量でありながら除去すべき毒素の吸着容量及び選択吸着性に優れ、経済的かつ環境負荷を抑えた経口投与用の医薬用吸着剤を提供する。【解決手段】精製セルロースまたは再生セルロースを炭化、賦活することにより得られた活性炭であって、平均細孔直径を１．５～２．２ｎｍ、ＢＥＴ比表面積を７００～３０００ｍ2／ｇ、平均粒径を１００～１１００μｍ、表面酸化物量を０．０５ｍｅｑ／ｇ以上、及び充填密度を０．４～０．８ｇ／ｍＬとする粒状活性炭からなり、経口投与用腎疾患または経口投与用肝疾患のための治療剤または予防剤として用いられることを特徴とする。【選択図】なし
