PROBLEM TO BE SOLVED: To provide an oral drug readily reducing the amounts of toxic substances and waste materials accumulated and generated in a living body in a short time.SOLUTION: The oral drug is obtained by combining an adsorbent, an oil liquid at normal temperature, granules containing a water-soluble polymer, and a purgative. A porous body such as medicinal carbon is preferable as the adsorbent, and a fatty acid ester is preferable as the oil liquid at normal temperature. A crystalline cellulose, a hyproxypropylcellulose, crospovidone, hypromellose, carmellose sodium and the like are preferably used as the water-soluble polymer, and a large intestine-stimulating purgative is preferably used as the purgative.COPYRIGHT: (C)2011,JPO&INPIT【課題】生体内において蓄積、発生する有害物質や老廃物の量を、簡便かつ短時間で低減できる経口薬の提供。【解決手段】吸着剤、常温液状油、及び水溶性高分子を含む造粒物、並びに瀉下剤を組み合わせてなる経口薬。吸着剤としては、薬用炭等の多孔体が好ましく;常温液状油としては、脂肪酸エステルが好ましく;水溶性高分子としては、結晶セルロース、ヒドロキシプロピルセルロース、クロスポビドン、ヒプロメロース、カルメロースナトリウム等が;瀉下剤としては大腸刺激性下剤が好ましく用いられる。【選択図】なし
