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.
