About Toraymyxin

Toraymyxin, a blood purification device, absorbs the bacterial toxin (endotoxin) that causes sepsis and septic shock using a special fiber. It consists of a plastic cylindrical container filled with a special fiber composite immobilized with the antibiotic polymyxin B, which has high affinity for endotoxin. In 1993, Toray received approval for manufacturing and marketing of the product from the “Health and Welfare Ministry of Japan,” and Toray Medical has been marketing it since 1994.
