Enoxaparin sodium acts as an anticoagulant, preventing blood clotting, and is useful for the treatment of thrombosis or the prevention of thrombosis in people at high risk of thrombosis. Because of its smaller molecular weight compared to heparin, it is less likely than heparin to cause allergic reactions, heparin-induced thrombocytopenia, effects on liver function, and to cause osteoporosis, and less likely than heparin to cause bleeding. The half-life of enoxaparin sodium is longer than that of heparin, and the bioavailability is higher than that of heparin, so enoxaparin sodium has certain advantages over heparin in this regard. However, if enoxaparin sodium is applied, it should be applied under the guidance of professional doctors, because the preventive dosage and the therapeutic dosage are different, and the dosage adjustment is also very delicate and needs the guidance of professional doctors.
