Enoxaparin Sodium is a low molecular weight heparin that can be used as an anticoagulant for the prevention and treatment of deep vein thrombosis or pulmonary embolism, in addition to unstable angina pectoris, and for the prevention of hemodialysis. Enoxaparin sodium is a commonly used clinical drug. Enoxaparin is a low molecular heparin with a longer half-life and higher bioavailability than heparin. Because of its smaller molecular weight than heparin, the chance of causing allergic reaction, heparin-induced thrombocytopenia, osteoporosis and other diseases is lower than that of heparin, the effect on liver function is lower than that of heparin, and the risk of causing hemorrhage is also much lower relative to heparin. Enoxaparin sodium mainly acts on coagulation factor II and coagulation factor X, so as to play an anticoagulant role, the drug is widely used in orthopedics or general surgery to prevent postoperative deep vein thrombosis, pulmonary embolism and other diseases, can also be used in clinical dialysis extracorporeal circulation to prevent thrombosis, the drug can be used in conjunction with aspirin to treat unstable angina pectoris and non-Q-wave infarction and other diseases. Adverse reactions to enoxaparin sodium include bleeding from skin and mucous membranes, rash, and bleeding gums. It is contraindicated in patients with bleeding and bleeding associated with severe clotting disorders. To avoid the risk of bleeding, the use of Enoxaparin Sodium should always be under the guidance of a medical professional, as the preventive dosage is different from the therapeutic dosage, which requires the guidance of a medical professional.
