Description

Desirudin is a direct inhibitor of human thrombin. It has a protein structure that is similar to that of hirudin, the naturally occurring anticoagulant present in the peripharyngeal glands in the medicinal leech, Hirudo medicinalis. Hirudin is a single polypeptide chain of 65 amino acids residues and contains three disulfide bridges. Desirudin has a chemical formula of C287H440N80O110S6 with a molecular weight of 6963.52.

It is mainly indicated for the prevention of deep vein thrombosis in hip replacement surgery patients. Common side effects include: Bleeding gums, collection of blood under the skin, coughing up blood, deep, dark purple bruise and difficulty with breathing or swallowing.

Pharmacology

Indication

Indicated as prophylaxis of deep vein thrombosis for patients undergoing hip replacement surgery.

Associated Conditions
Pharmacodynamics

Desirudin results in dose-dependent prolongation of the activated partial thromboplastin time (aPTT).

Mechanism of action

Desirudin is a direct, highly selective thrombin inhibitor. Reversibly binds to the active thrombin site of free and clot-associated thrombin. Inhibits fibrin formation, activation of coagulation factors V, VII, and XIII, and thrombin-induced platelet aggregation resulting in a dose-dependent prolongation of the activated partial thromboplastin time (aPTT).

Absorption

Absorption is complete after subcutaneous administration. Time to peak in plasma is 1 to 3 hours.

Volume of distribution

0.25 L/kg.

Protein binding

Desirudin binds specifically and directly to thrombin, forming an extremely tight, non-covalent complex with an inhibitionconstant of approximately 2.6 x 10-13 M. Thus, free or protein bound desirudin immediately binds circulating thrombin.

Metabolism

Human and animal data suggest that desirudin is primarily eliminated and metabolized by the kidney. The total urinary excretion of unchanged desirudin amounts to 40 to 50% of the administered dose. Metabolites lacking one or two C-terminal amino acids constitute a minor proportion of the material recovered from urine (< 7%). There is no evidence for the presence of other metabolites. This indicates that desirudin is metabolized by stepwise degradation from the C-terminus probably catalyzed by carboxypeptidase(s) such as carboxypeptidase A.

Route of elimination

Urine (40% to 50% as unchanged drug).

Half life

~2 hours.

Clearance

1.5 to 2.7 mL/min/kg.
