An adsorbent for oral administration characterized by comprising active carbon spheres having an average particle diameter of from 50 to 200 µm, a specific surface area determined by the BET method of 700 m2/g or more and a bulk density of less than 0.54 g/mL. Because of having a high adsorbing capacity, this adsorbent can adsorb a large amount of a toxic substance within the retention time thereof in the intestinal tract and shows a remarkable increase in the adsorption amount of a high-molecular weight compound.
Un adsorbant pour administration orale caractérisé en ce qu~il comprend des sphères de charbon actif ayant une granulométrie moyenne comprise entre 50 et 200 µm, une surface spécifique déterminée par la méthode BET de 700 m /g ou plus et une densité apparente de moins de 0,54 g/mL. En raison de sa haute capacité adsorbante, cet adsorbant peut adsorber une grande quantité de substance toxique dans le temps de rétention de celle-ci dans le tube intestinal et présente une augmentation considérable de la quantité d~adsorption d~un composé à haut poids moléculaire.
