Bilirubin adsorption column Medisorba BL-300.
Bilirubin adsorption column Medisorba BL-300 (Kuraray Medical Inc.) for the treatment of hyperbilirubinemia is introduced. The adsorbent packed in this column is the porous anion exchange resin coated with hydrophilic 2-hydroxyethyl methacrylate copolymer in order to improve blood compatibility. The adsorbent showed a high adsorption rate for direct bilirubin and indirect bilirubin in patient plasma in vitro. This column is used in plasmaperfusion therapy in clinical use. BL-300 showed high removal rate for direct bilirubin, indirect bilirubin and bile acid in clinical evaluation. BL-300 is approved in Japan and it has been used for the treatment of hyperbilirubinemia caused by many diseases such as liver failure and hepatitis.
