Removal of lepirudin, a recombinant hirudin, by hemodialysis, hemofiltration, or plasmapheresis.

Abstract

Lepirudin (recombinant hirudin), a direct thrombin inhibitor, is an effective alternative method of anticoagulation in patients with heparin-induced thrombocytopenia. However, because it is eliminated by the kidneys, the half-life of lepirudin may be substantially prolonged in patients with renal failure. Patients undergoing hemodialysis must be closely monitored, and therapy must be individualized based on each patient's ability to clear the drug. Current literature on the removal of lepirudin by dialysis or plasmapheresis is limited, but available data suggest that lepirudin can be removed with these methods. The ability of filtration systems to remove lepirudin from the blood is highly dependent on the membrane material used in the system. Understanding the effects of hemodialysis, hemofiltration, and plasmapheresis on lepirudin levels is important, especially since no antidote is available to treat elevated serum lepirudin concentrations.
