Enoxaparin sodium is anticoagulant, preventing blood clotting, for the treatment of thrombosis or the prevention of high-risk groups of thrombosis has a certain role. Because of its small molecular weight relative to heparin, it is less likely than heparin to cause allergic reactions, heparin-induced thrombocytopenia, liver function effects, and osteoporosis, and less likely to cause bleeding. Enoxaparin sodium has a longer half-life than heparin and a higher bioavailability than heparin, so enoxaparin sodium has some advantages over heparin in this regard. However, if enoxaparin sodium is used, it should be applied under the guidance of a professional doctor, because the dosage of prevention and therapeutic dosage are not the same, and the adjustment of dosage is also very exquisite, requiring the guidance of a professional doctor.
