ADSORBENT FOR ORAL ADMINISTRATION THERAPEUTIC AGENT FOR RENAL DISEASES AND THERAPEUTIC AGENT FOR HEPATIC DISEASES

摘要

An object of the present invention is to provide an adsorbent for oral administration capable of adsorbing a large amount of indole in the presence of bile acid. The above problem is solved by a process for producing a polyurethane foam having a specific surface area of 800 m ² / g or more, a bulk density of 0.3 to 0.8 g / mL, a pore volume of less than 3 nm, (1): Vm = Vmic / Vmet (1) wherein Vmic is a pore volume of less than 3 nm in diameter and Vmet is a pore volume of 3 to 50 nm in pore diameter, And a spherical activated carbon having a porosity ratio (Vm) of not less than 3.0 can be solved by an adsorbent for oral administration.
