ADSORPTION AGENTS FOR ORAL ADMINISTRATION, MEANS FOR THE TREATMENT OR PREVENTION OF KIDNEY DISORDERS AND MEANS FOR THE TREATMENT OR PREVENTION OF ILL. DISEASES

摘要

An adsorbent for oral administration, 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 1000 m2/g or more; and an adsorbent for oral administration, 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 1000 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. The adsorbents for oral administration exhibit a useful selective adsorbability, that is, a less adsorbability of useful substances in a body, and a greater adsorbability of toxic substances.
