Abstract

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 m 2 /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 m 2 /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.

Claims (15)

1 . An adsorbent for oral administration, 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 m 2 /g or more.

2 . The adsorbent for oral administration according to claim 1 , wherein a total amount of basic groups on the spherical activated carbon is 0.40 meq/g or more.

3 . An adsorbent for oral administration, 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 m 2 /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.

4 . A pharmaceutical composition for treating or preventing a renal disease, comprising the adsorbent for oral administration according to claim 1 and a pharmaceutically acceptable carrier or diluent.

5 . A pharmaceutical composition for treating or preventing a renal disease, comprising the adsorbent for oral administration according to claim 3 and a pharmaceutically acceptable carrier or diluent.

6 . A pharmaceutical composition for treating or preventing a disease bearing a relationship to or deteriorated by a uremic substance, comprising the adsorbent for oral administration according to claim 3 and a pharmaceutically acceptable carrier or diluent.

7 . A pharmaceutical composition for treating or preventing a disease bearing a relationship to or deteriorated by a uremic substance, comprising the adsorbent for oral administration according to claim 3 and a pharmaceutically acceptable carrier or diluent.

8 . A pharmaceutical composition for treating or preventing a liver disease, comprising the adsorbent for oral administration according to claim 1 and a pharmaceutically acceptable carrier or diluent.

9 . A pharmaceutical composition for treating or preventing a liver disease, comprising the adsorbent for oral administration according to claim 3 and a pharmaceutically acceptable carrier or diluent.

10 . A method for treating or preventing a renal disease, comprising administering to a subject in need thereof, the adsorbent for oral administration according to claim 1 , in an amount effective thereof.

11 . A method for treating or preventing a renal disease, comprising administering to a subject in need thereof, the adsorbent for oral administration according to claim 3 , in an amount effective thereof.

12 . A method for treating or preventing a disease bearing a relationship to or deteriorated by a uremic substance, comprising administering to a subject in need thereof, the adsorbent for oral administration according to claim 1 , in an amount effective thereof.

13 . A method for treating or preventing a disease bearing a relationship to or deteriorated by a uremic substance, comprising administering to a subject in need thereof, the adsorbent for oral administration according to claim 3 , in an amount effective thereof.

14 . A method for treating or preventing a liver disease, comprising administering to a subject in need thereof, the adsorbent for oral administration according to claim 1 , in an amount effective thereof.

15 . A method for treating or preventing a liver disease, comprising administering to a subject in need thereof, the adsorbent for oral administration according to claim 3 , in an amount effective thereof.
