For prevention of deep vein thrombosis, which may result in pulmonary embolism, following knee surgery.
Enoxaparin is indicated for the prevention of ischemic complications in unstable angina and in non Q-wave myocardial infarction; it is indicated in conjunction with percutaneous intervention and/or other treatment for the management of acute ST elevation myocardial infarction. Enoxaparin is also indicated in the prophylaxis of DVT in abdominal surgery, hip replacement, knee replacement, or medical patients with severely restricted mobility during acute illness. Additionally, enoxaparin is indicated for the inpatient treatment of DVT with or without pulmonary embolism and the treatment of outpatient DVT without pulmonary embolism.
Investigated for use/treatment in cardiovascular disorders and coronary artery disease.
Dalteparin is used as a prophylaxis for deep-vein thrombosis and pulmonary embolisms in patients undergoing general surgery (e.g., abdominal, gynecologic, urologic), and in patients with acute medical conditions (e.g. cancer, bed rest, heart failure, severe lung disease). It is also used in patients who have severely restricted mobility, which poses a risk for thromboembolic complications. Dalteparin is also used concomitantly with aspirin and/or other therapy (e.g., nitrates, -adrenergic blockers, clopidogrel, platelet glycoprotein [GP] IIb/IIIa-receptor inhibitors) to reduce the risk of acute cardiac ischemic events. The patients who undergo this treatment combination have unstable angina or non-ST-segment elevation/non-Q-wave myocardial infarction (i.e., non-ST-segment elevation acute coronary syndromes). It is also used in the prevention of clotting during hemodialysis and hemofiltration in connection with acute renal failure or chronic renal insufficiency.
Tinzaparin is used for the prevention of postoperative venous thromboembolism in patients undergoing orthopedic surgery and in patients undergoing general surgery who are at high risk of developing postoperative venous thromboembolism. It is also used for the treatment of deep vein thrombosis and/or pulmonary embolism. It is indicated for use in preventing clot formation in indwelling intravenous lines for hemodialysis.
Nadroparin is used for prophylaxis of thromboembolic disorders and general surgery in orthopedic surgery, treatment of deep vein thrombosis, prevention of clotting during hemodialysis and treatment of unstable angina and non-Q wave myocardial infarction.
Bemiparin is indicated in the following cases: To prevent blood clots in the veins after general abdominal surgery in patients with a moderate risk of venous thromboembolism; in the prevention of the thromboembolic disease in non-surgical patients; prevention of clotting in the extracorporeal circuit during hemodialysis; to prevent blood clots in the veins after a major orthopedic surgery in patients with high risk of venous thromboembolism; secondary prevention of venous thromboembolism; recurrence in patients with deep vein thrombosis; transient prevention and treatment of deep vein thrombosis (DVT).
By the FDA, reviparin is indicated for the treatment of deep vein which may lead to pulmonary embolism in pediatric patients. It is also indicated for the long-term treatment of acute deep vein thrombosis with or without pulmonary embolism in pregnant patients.
Used in the prevention and treatment of venous thromboembolism (deep vein thrombosis and pulmonary embolism) and in the treatment of myocardial infarction.
Used in the prevention and treatment of venous thromboembolism (deep vein thrombosis and pulmonary embolism) and in the treatment of myocardial infarction.
Investigated for use/treatment in thrombosis.
Ardeparin, an anticoagulant, is a fractionated heparin. It acts at multiple sites in the normal coagulation system to inhibit reactions that lead to the clotting of blood and the formation of fibrin clots both in vitro and in vivo.
This drug has an immediate onset of action. Enoxaparin increases Thrombin Time (TT) and activated partial thromboplastin time (aPTT), preventing and reducing thromboembolic complications such as DVT, pulmonary embolism, and ischemic cardiac complications. Administered at 1.5 mg/kg subcutaneously in a pharmacodynamic study, enoxaparin led to a higher ratio of anti-Factor Xa to anti-Factor IIa activity (mean SD, 14.03.1) (based on areas under anti-Factor activity versus time curves) when compared to that of heparin (mean SD, 1.220.13). Increases in the TT and aPTT were 1.8 times those of the control group. Enoxaparin at 1 mg/kg subcutaneously every 12 hours led to aPTT values of 45 seconds or less in most patients. Average aPTT prolongation time on Day 1 was approximately 16% higher than on Day 4 of enoxaparin therapy. Caution is advised during treatment with enoxaparin - the risk of hemorrhage and thrombocytopenia is increased. In pregnant women with prosthetic mechanic heart valves, the risk of thromboembolism is increased.
Dalteparin has an antithrombin binding site that is essential for high affinity binding to the plasma protein antithrombin (ATIII). Anti-Xa activity of plasma is used as both as an estimate of clotting activity, and as a basis to determine dosage. Its use should be avoided in patients with a creatinine clearance less than 20mL/min. In these patients, unfractionated heparin should only be used. As for monitoring, active partial thromboplastin time (aPTT) will only increase at high doses of low molecular weight heparins (LMWH). Therefore, monitoring aPTT is not recommended. However, anti-Xa activity can be measured to monitor the efficacy of the LMWH.
Tinzaparin, like other LMWHs, have a higher anti-Xa activity than anti-IIa activity. The anti-Xa activity of tinzaparin is 2.0 +/- 0.5 times greater than its to anti-IIa activity. Heparin exhibits approximately equal inhibitory activity against Xa and IIa. Tinzaparin is an anticoagulant that blocks the formation of thrombi. Like all LMWHs, tinzaparin only causes activated partial thromboplastin time (aPTT) prolongation at higher doses and routine monitoring is not recommended. However, anti-factor Xa levels may be monitored in some conditions such as pregnancy and renal dysfunction. Its use should be avoided in patients with a creatinine clearance less than 20 mL/min. In these patients, unfractionated heparin should be used. Tinzaparin can be used in patients who have a creatinine clearance between 20-30 mL/min, giving it the highest safety threshold for use in renal failure patients compared to all the LMWHs.
Nadroparin is a low molecular weight heparin that is composed of a heterogeneous mixture of sulfated polysaccaride glycosaminoglycan chains. Th mean molecular weight is approximately 4300 daltons. The ratio of anti-Xa activity to anti-IIa is 3.5:1 whereas it is about 1:1 for heparin. Its use should be avoided in patients with a creatinine clearance less than 40mL/min. In these patients, unfractionated heparin should only be used. As for monitoring, active partial thromboplastin time (aPTT) will only increase at high doses of low molecular weight heparins (LMWH). Therefore, monitoring aPTT is not recommended. However, anti-Xa activity can be measured to monitor the efficacy of the LMWH.
Bemiparin is an anticoagulant classified under the broad category of low molecular weight heparins. In humans, bemiparin has been proven to possess antithrombotic activity and, at therapeutic doses, does not significantly prolong global clotting laboratory tests.
Reviparin is been shown to present significant inhibition of smooth muscle cell migration and proliferation in human cell cultures without affecting endothelial cell growth.

Absorption
Well absorbed following subcutaneous administration, with a mean bioavailability of 92% (based on anti-factor Xa activity).
Absorption
Mean absolute bioavailability of enoxaparin, after 1-2 mg/kg given subcutaneously is approximately 100% in healthy volunteers. The absorption of enoxaparin is proportional to the dose, demonstrating linear absorption. The average maximum plasma anti-Xa activity is reached 3 to 5 hours after a subcutaneous injection. A 30 mg IV bolus preceding an immediate 1 mg/kg SC every twice a day led to maximum anti-Factor Xa levels of 1.16 IU/mL. Steady-state is reached within 3-4 days of treatment with a Cmax of 1.2 IU/mL. The AUC under the thrombin generation curve was 305 +/- 48.

In a study of healthy volunteers, bemiparin 3500 IU achieved more anti-Xa activity than enoxaparin 4000 IU, measured by the area under the curve. The peak of anti-Xa activity was reached at 3h post-administration, and there were anti-Xa measurable levels up to 16 h after subcutaneous injection.
Elimination half-life for anti-factor Xa activity averages 3.3 hours following a single intravenous dose, while elimination half-life for anti-factor IIa activity averages 1.2 hours following a single intravenous dose.
The half-life of enoxaparin is about 4 hours after a single dose administered subcutaneously and about 7 hours after several doses. One source mentions a half-life ranging from 1 hour to 4.5 hours.
Terminal Half life: Intravenous - 2 hours. Subcutaneous - 3-5hours
Anti-Xa activity is 82 minutes. Anti-IIa activity is 71 minutes.
In healthy patients, the half life is between 3.5hrs to 11.2hrs following subcutaneous administration.
Bemiparin, when administered in the dose range of 2,500 IU to 12,500 (therapeutic dosing), it has an approximate half-life of 5-6 hours.
Ardeparin binds to antithrombin III, accelerating its activity in inactivating factor Xa and thrombin, thereby inhibiting thrombosis. Ardeparin also binds to heparin cofactor II, inhibiting thrombin. Ardeparin does not effect prothrombin time (PT) assays and may prolong activated partial thromboplastin time (APTT). Ardeparin has double the anti-factor Xa activity versus anti-factor IIa activity, compared to unfractionated heparin which has approximately equal anti-factor Xa activity and anti-factor IIa activity.
Enoxaparin binds to antithrombin III, a serine protease inhibitor, forming a complex that irreversibly inactivates factor Xa, which is frequently used to monitor anticoagulation in the clinical setting. Following factor Xa inactivation, enoxaparin is released and binds to other anti-thrombin molecules. Factor IIa (thrombin) is directly inhibited by enoxaparin, however with less potency than unfractionated heparin (UFH). Due to the cascade of effects resulting from enoxaparin binding, thrombin is unable to convert fibrinogen to fibrin and form a clot, preventing thromboembolic events.
M118 is a novel drug candidate that has been, through Momenta's proprietary technology, rationally engineered with attributes of monitorability, reversibility, flexible administration (intravenous and subcutaneous), and both potent and predictable anti-Xa (aXa) and anti-IIa (aIIa) activity to provide anticoagulant therapy to patients with ACS. M118 is designed to interact at multiple points in the coagulation cascade by selectively binding to anti-thrombin III and thrombin, two critical factors in the formation of clots.
Dalteparin potentiates the activity of ATIII, inhibiting the formation of both factor Xa and thrombin. The main difference between dalteparin and unfractionated heparin (UH) is that dalteparin preferentially inactivates factor Xa. As a result, only a slight increase in clotting time [(i.e. activated partial thomboplastin time (APTT)] is observed relative to UH. For this same reason, APTT is not used to monitor the effects of dalteparin except as an indicator for overdosage.
Tinzaparin binds to the plasma protein antithrombin III, forming a complex with then accelerates the inhibition of factor Xa. Its affinity for factor Xa is 2-4 times greater than that of unbound ATIII. The inactivation of factor Xa in turn will exponentially generation of thrombin (factor IIa) molecules, which is needed to activate fibrinogen to fibrin. The coagulation cascade is inhibited because fibrin cannot be formed in the presence of tinzaparin. Like all LMWH, it cannot be given intramuscularly due to increased risk of hematoma.
The mechanism of action for nadroparin is similar to all other LMWHs. Like all LMWHs, nadroparin has a pentasaccharide sequence which binds to ATIII, which potentiates the action of ATIII. This complex greatly accelerates the inactivation of factor Xa and factor IIa. As a result, the coagulation cascade is inhibited.
This drug is a second-generation low molecular weight heparin (LMWH). It has a very low mean molecular weight (3600 Dalton), a long half-life (5.3 hrs) and a large anti-Xa: anti-IIa ratio (8:1). The mechanism of action of bemiparin is inhibition of factor Xa, which is a necessary step in the clotting cascade. Factor-Xa is necessary for the propagation of a thrombus. Combined with various co-factors that bind to activated platelets, Factor-Xa increases coagulation by converting prothrombin to thrombin. Activated Factor-X, bound as part of the prothrombinase complex on the external surface of activated platelets, converts significant amounts of prothrombin to thrombin, promoting the so-called thrombin burst, referring to a burst of thrombin release. A secondary but less potent mechanism of action of this drug is binding to antithrombin III and activated factor II (Factor IIa), which further prevents the propagation of thrombi. Due to its excellent pharmacological profile-the second-generation LMWH with the lowest molecular weight, the longest half-life and the highest anti-Factor Xa/anti-Factor IIa activity ratio-it can be safely used in special categories of patients (children, elderly, patients with renal impairment and congestive heart failure). Several studies demonstrated its safety and efficacy, while cost analyses show the economic benefits of bemiparin treatment as compared to other heparins.
