ADSORBENTS FOR ORAL ADMINISTRATION, REMEDIES OR PROPHYLACTIC AGENT FOR KIDNEY DISEASES AND REMEDIES OR PROPHYLACTIC AGENT FOR LIVER DISEASES

摘要

PROBLEM TO BE SOLVED: To provide an adsorbents for oral administration, exhibiting a useful selective adsorbability, that is, less adsorbability of useful substances in a body, and greater adsorbability of toxic substances.;SOLUTION: This adsorbent for oral administration is characterized by comprising a spherical activated carbon prepared from a thermosetting resin as a carbon source, wherein a diameter is 0.01 to 1 mm, and a specific surface area determined by Langmuir's adsorption equation is 1,000 m²/g or more; and the adsorbent for oral administration is characterized by comprising a surface-modified spherical activated carbon prepared from a thermosetting resin as a carbon source, wherein a diameter is 0.01 to 1 mm, a specific surface area determined by Langmuir's adsorption equation is 1,000 m²/g or more, a total amount of acidic groups is 0.40 to 1.00 meq/g, and a total amount of basic groups is 0.40 to 1.10 meq/g.;COPYRIGHT: (C)2006,JPO&NCIPI
