Usage


What is Enoxaparin sodium?


 Enoxaparin sodium is a new anticoagulant. It is used for various indications including prevention of deep vein thrombosis (DVT). Enoxaparin sodium is a hemodilution drug prepared from heparin sodium, and its active ingredient is a mixture of natural polysaccharides.


Enoxaparin sodium is intended for use in the treatment of deep vein thrombosis; prophylaxis of ischemic complications of unstable angina and non-Q-wave myocardial infarction, and treatment of acute deep vein thrombosis. Besides, Enoxaparin Sodium also can be used as a biomarker for diagnosis of atrial fibrillation cause of stroke.
