MEDICINAL ADSORBENT

PROBLEM TO BE SOLVED: To provide a medicinal adsorbent which hardly causes side effects such as constipation, is excellent in the adsorption of ionic organic compounds causing uremia and the like, exhibits sufficient adsorption performance at a small dose, and inhibits the adsorption of compounds necessary for living bodies. SOLUTION: This medicinal adsorbent is characterized by comprising spherical activated carbon which is obtained by carbonizing and activating a spherical phenolic resin produced by the condensation reaction of a phenol compound with an aldehyde compound in a phenol compound/aldehyde compound condensation reaction molar ratio of 1.0 to 2.3, and satisfies a specific surface area of 800 to 2,000 m2/g, a pore volume of 0.2 to 1.0 mL/g, a packing density of 0.5 to 0.7 g/mL, an average pore diameter of 1.7 to 2.0 nm, the maximum particle diameter of ≤425 μm, an average particle diameter of ≤350 μm, a total pore (having pore diameters of ≤1.0 nm) volume of ≥55% based on the total volume of all the pores, and a total pore (having pore diameters of 20 to 1,000 nm) volume of ≤0.04 mL/g.
