Heparin Sodium
CAS No.: 9041-08-1 (Anticoagulant)

Short Description:

Source: Extracted from pig intestinal mucosa
Function and use: It is an anticoagulant. It affects many aspects of the coagulation process and can prolong the coagulation time and prothrombin time. This product has rapid anticoagulant effect both in vivo and in vitro. It mainly acts on the formation of fibrin and can also reduce platelet aggregation. For the prevention and treatment of thromboembolic diseases, such as myocardial infarction, pulmonary embolism, cerebrovascular embolism, peripheral venous thrombosis, etc., it can prevent the formation and expansion of thrombus. It can also be used in the early stage of DIC and other anticoagulation in vitro and in vivo. Early application can prevent depletion of fibrinogen and coagulation factors. It can also be used as an anticoagulant in vitro instead of citrate during blood transfusion or during cardiopulmonary bypass.

Indications

1. Prevent venous thromboembolic diseases in general surgery and orthopedic surgery.
2. In non-surgical procedures, it is used in situations with moderate or high risk of venous thrombosis to prevent venous thromboembolic diseases.
3. Secondary prevention of venous thromboembolism recurrence in patients with deep vein thrombosis and transient risk factors.
4. Prevent the formation of blood clots during extracorporeal circulation during hemodialysis.
5. Treat formed deep vein thrombosis with or without pulmonary embolism.
