Adsorption characteristics of creatinine by activated carbon beads consisting of about 67% activated carbon powder in ager were studied in vitro and compared with those of Kremezin^<[◯!R]> from the standpoint of usefulness for sequestering uremic wastes and uremic toxins exsorbed into the intestine. The extent and rate of creatinine adsorption on carbon in the beads were almost equal to those of the naked powder, and the preparation also demonstrated a similar adsorption behavior for creatinine as compared with Kremezin under the conditions of the presence of various ionic and nonionic additives. Furthermore, uremic peaks 2a and 2b on HPLC specific to chronic renal failure were readiy eliminated by the treatment of the beads in the uremic plasma. On the other hand, although the adsorption capacities of Kremezin for drugs were generally equal to those of medical carbon, the adsorption rate by Kremezin was smaller, but inferiority was not so serious as to make Kremezin useless as an oral antidote in acute intoxications brought on by drugs.
