ADSORBENT FOR AN ORAL ADMINISTRATION, AND AGENT FOR TREATING OR PREVENTING RENAL OR LIVER DISEASE

摘要

An adsorbent for an oral administration, comprising a spherical activated carbon wherein an average particle diameter is 50 to 200 µm, a specific surface area determined by a BET method is 700 m2/g or more, and a bulk density is less than 0.54 g/mL is disclosed. The adsorbent for an oral administration has a high adsorbability, and is capable of adsorbing a large amount of toxins during a retention period in an intestine, and of remarkably increasing an adsorption amount of compounds having a large molecular weight.
