Biological Activity
| ln Vivo | Desirudin (CGP 39393, 0.75-3.0 mg/kg, bolus plus infusion treatment, cardiopulmonary bypass dog model) can effectively suppress thrombosis [1]. Desirudin (0.01-1 mg/kg, intravenous and subcutaneous injection, rat shunt model) suppresses thrombosis with ED50 values of 0.3 mg/kg (iv) and 1.0 mg/kg (sc) and inhibits venous stasis thrombosis , ED50 values are 0.01 mg/kg (iv) and 0.45 mg/kg (sc)[2]. |
| Animal Protocol |
Animal/Disease Models: Male mongrel dog cardiopulmonary bypass model [1] Doses: 1.0 mg/kg + 0.75 mg/kg/h, 1.0 mg/kg + 1.50 mg/kg/h, 1.0 mg/kg + 2.25 mg/kg/h, 1.0 mg/kg + 3.0 mg/kg/hour. Route of Administration: Administration by bolus plus infusion Experimental Results: Inhibition of clot formation without adverse hemodynamic or hematological effects. Animal/Disease Models: Rat cotton thread thrombosis shunt model [2] Doses: approximately 0.01-1 mg/kg Route of Administration: intravenous (iv) (iv)injection, subcutaneous injection Experimental Results: Inhibition of thrombosis, ED50 value is 0.3 mg/kg (iv) and 1.0 mg/kg (subcutaneous). Inhibits venous stasis and thrombosis with ED50 values of 0.01 mg/kg (iv) and 0.45 mg/kg (sc). |
| ADME/Pharmacokinetics |
Absorption, Distribution and Excretion Absorption is complete after subcutaneous administration. Time to peak in plasma is 1 to 3 hours. Urine (40% to 50% as unchanged drug). 0.25 L/kg. 1.5 to 2.7 mL/min/kg. Metabolism / Metabolites 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. Biological Half-Life ~2 hours. |
| Toxicity/Toxicokinetics |
Hepatotoxicity In the large prelicensure clinical trials of desirudin, serum aminotransferase and alkaline phosphatase elevations were not reported. Furthermore, there have been no case reports of clinically apparent liver injury attributable to desirudin therapy. There have been reports of hypersensitivity reactions to desirudin therapy and hepatic involvement often occurs during severe drug induced hypersensitivity reactions. Likelihood score: E (unlikely cause of clinically apparent liver injury). Effects During Pregnancy and Lactation ◉ Summary of Use during Lactation Desirudin is no longer marketed in the United States. Because no information is available on the use of desirudin during breastfeeding, an alternate drug is preferred. ◉ Effects in Breastfed Infants Relevant published information was not found as of the revision date. ◉ Effects on Lactation and Breastmilk Relevant published information was not found as of the revision date. 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. |

| Additional Infomation |
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. Desirudin is a parenterally administered, selective thrombin inhibitor that is used to decrease the risk of deep vein thrombosis and pulmonary embolus in patients undergoing hip replacement surgery. Desirudin has not been linked to serum enzyme elevations during therapy or to clinically apparent liver injury with jaundice. Desirudin is a synthetic recombinant form of the naturally occurring hirudin, the anticoagulant substance found in leech. Desirudin is a selective and almost irreversible inhibitor of thrombin, both free and clot-bound, by blocking its active site. This anticoagulant agent has no effect on other components of the hemostatic system. Desirudin is particularly used to prevent deep vein thrombosis in patients undergoing hip and knee replacement surgery. Drug Indication Indicated as prophylaxis of deep vein thrombosis for patients undergoing hip replacement surgery. Prevention of deep venous thrombosis in patients undergoing elective hip or knee replacement surgery. 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). Pharmacodynamics Desirudin results in dose-dependent prolongation of the activated partial thromboplastin time (aPTT). |

| Solubility (In Vivo) |
Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples. Injection Formulations (e.g. IP/IV/IM/SC) Injection Formulation 1: DMSO : Tween 80: Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution.
