Anti-hirudin antibodies alter pharmacokinetics and pharmacodynamics of recombinant hirudin
Thrombosis and Haemostasis, 2003SummaryRecombinant hirudin (r-hirudin) is a potent direct thrombin inhibitor with immunogenic properties. Anti-hirudin antibodies (aHAb) are detected in up to 74% of patients treated with r-hirudin for more than 5 days. aHAb may alter the pharmaco-kinetics and pharmacodynamics of r-hirudin.The effects of aHAb on the pharmacokinetics of r-hirudin were ...

Blood, 2011
Abstract Abstract 4321 Recombinant versions of hirudin such as lepirudin (Refludan®) and desirudin (Iprivask®) are currently used as parenteral anticoagulants for various indications. The recombinant hirudin preparations differ from the natural hirudin in lacking a sulfate group on tyrosine at the 63rd position and a ...

Isolation and Characterization of Hirudin Isoinhibitors and Sequence Analysis of Hirudin PA
Biological Chemistry Hoppe-Seyler, 1986A five-step isolation procedure has been developed for the purification of isoforms of hirudin (isohirudins) from whole leeches. The final purification of two thrombin-inhibiting preparations by reversed-phase high-performance liquid chromatography yielded several isohirudins with either N-terminal valine or isoleucine but with identical inhibition ...

The History of Leeching and Hirudin
Haemostasis, 2009Leeching is an art dating back at least to ancient Egypt. It reached its zenith in the late 18th and early 19th centuries. The antithrombotic quality of leech saliva was first noted by Haycraft in 1884 and the active anticoagulant ingredient isolated in 1904 by Jacoby. He gave this agent the name ‘hirudin’. Hirudin was isolated in pure crystalline form

Pharmacology of Recombinant Hirudin
Seminars in Thrombosis and Hemostasis, 2002Hirudin is the anticoagulative product of the salivary glands of the medical leech Hirudo medicinalis. It is characterized by a direct, bifunctional inhibition mechanism and a high, exclusive specificity and a strong ability to bind to thrombin (tight binding).

Hirudin for Diagnostic Purposes
Haemostasis, 2009Hirudin serves as a versatile tool for the control of thrombin activity in hemostaseology. It may be added in excess to blood, plasma or test mixtures to prevent catalytic and nonenzymatic effects of thrombin. It may be used to quench thrombin activity upon extensive or limited action.

Hirudin In Renal Insufficiency
Seminars in Thrombosis and Hemostasis, 2002Recombinant hirudins (r-hirudins) are potent direct thrombin inhibitors increasingly used for alternative anticoagulation, especially in heparin-induced thrombocytopenia. R-hirudins are almost exclusively eliminated by the kidneys, and a close correlation between r-hirudin clearance and endogenous creatinine clearance has been observed.

BioDrugs, 1998
Hirudin is a specific thrombin inhibitor which acts independent of antithrombin III and is able to bind to fluid phase and clot bound thrombin. It has become available for clinical use by production with recombinant techniques just recently. Hirudin produces a relatively stable level of anticoagulation when compared with heparin.
