Enoxaparin sodium, commonly known as low molecular heparin sodium, has the same anticoagulant effect as low molecular heparin calcium. It is mainly used to prevent thrombosis, treat thromboembolic diseases, especially to prevent thrombosis in patients who are bedridden for a long time after surgery.

　　Small molecule heparin sodium is mainly used in the following aspects: First, for the treatment of deep vein thrombosis, the clinical symptoms are relatively mild, and pulmonary embolism does not require surgery or thrombolytic therapy. Treatment of unstable angina and non-Q-wave myocardial infarction may be combined with aspirin. It's used during dialysis to prevent blood clots from forming. Thrombolytic agents are available for the treatment of acute ST-segment elevation myocardial infarction. In short, enoxaparin sodium is a kind of low-molecular-weight heparin sodium. Like low-molecular-weight heparin calcium, enoxaparin sodium is widely used for various thromboembolism and prevention of various kinds of thromboembolism, and is widely used in the departments of heart, vein, cardiothoracic surgery, general surgery and orthopedics.
