Sodium low molecular heparin is an anticoagulant, one of the low molecular weight heparins, and is the sodium salt of the aminoglucan sulfate fragment obtained by cleavage of sodium heparin. Its molecular weight is generally less than 8 kDa.
Sodium heparin, a low molecular weight heparin, is characterized by selective anticoagulant factor Xa activity with less effect on thrombin and other coagulation factors. The smaller the molecular weight, the stronger the anticoagulant factor Xa activity, which reduces the risk of bleeding compared with ordinary heparin.
Clinically, it can be used for the treatment of acute deep vein thrombosis; the prevention of blood clot formation during hemodialysis; the treatment of unstable angina and non-Q-wave myocardial infarction and the prevention of thrombosis related to surgery. The use of low molecular weight heparin sodium should be under the supervision of a medical professional.
