Enoxaparin sodium is widely used as an anticoagulant to prevent and treat blood clots. It is commonly administered to patients undergoing surgery, particularly orthopedic procedures like hip or knee replacements, to reduce the risk of deep vein thrombosis (DVT) and pulmonary embolism (PE). It is also used in the management of acute coronary syndromes, such as unstable angina and non-ST-segment elevation myocardial infarction, to prevent further clot formation. Additionally, it is prescribed for patients with certain medical conditions, like atrial fibrillation or prolonged immobility, who are at high risk of thromboembolic events. The drug is typically injected subcutaneously and is favored for its predictable anticoagulant effect and reduced need for frequent monitoring compared to other anticoagulants.
