HEPARIN SODIUM 12,500 UNITS IN SODIUM CHLORIDE 0.45% IN PLASTIC CONTAINER (heparin sodium)

Genetically Validated
Cardiovascular Approved 1984-01-31

Heparin Sodium is an anticoagulant indicated for the prophylaxis and treatment of venous thrombosis, pulmonary embolism, and peripheral arterial embolism. It is used to prevent postoperative deep venous thrombosis (DVT) and pulmonary embolism in patients undergoing major abdominothoracic surgery or those at high risk for thromboembolic disease. Additionally, it is indicated for atrial fibrillation with embolization, the treatment of acute and chronic consumptive coagulopathies (disseminated intravascular coagulation), and as an anticoagulant in blood transfusions, extracorporeal circulation, dialysis, and arterial/cardiac surgery.

How HEPARIN SODIUM 12,500 UNITS IN SODIUM CHLORIDE 0.45% IN PLASTIC CONTAINER Works

Heparin acts by binding to Antithrombin III, inducing a conformational change that markedly enhances its ability to inhibit activated coagulation factors, specifically Factor Xa and Factor IIa (thrombin). By inhibiting these factors and the activation of fibrin stabilizing factor, heparin prevents the formation of stable fibrin clots. Heparin does not possess intrinsic fibrinolytic activity and therefore will not lyse existing thrombi.

HEPARIN SODIUM 12,500 UNITS IN SODIUM CHLORIDE 0.45% IN PLASTIC CONTAINER Target & Pathway

Pro

Target

FACTOR XA (Coagulation Factor Xa) Coagulation Factor

A key enzyme in the blood clotting cascade that converts prothrombin to thrombin. Inhibiting Factor Xa prevents clot formation, reducing risk of stroke in atrial fibrillation and treating/preventing venous thromboembolism.
