Heparin sodium is the sodium salt of sulfated glycosaminoglycan, it is a mixture of different kinds of different molecular weight molecules, which can keep the activity of the composition to against different factor in blood clotting stage. It exists in mammals and usually be extracted from mammals of the intestinal mucosa or the right organization of the mammals which are feed by human.
Heparin has strong anticoagulant effect, it is the primary drug choice to prevent deep vein thrombosis and thrombus diseases , although it has more than 60 years of history in clinic, but until now there is no substitutes can completely replace it, so it is still the most important biochemical drugs of anti coagulation and anti thrombosis.

Function:
Common Heparin is a mixture containing a variety of amino dextran glucoside, it can delay or prevent blood clotting in vitro and in vivo. Heparin can reduce blood fat, decrease LDL and VLDL, increase HDL, changes blood viscosity, protect vascular endothelial cells, prevent atherosclerosis, promote blood flow, improve the coronary circulation.
It has a wide range of uses in medicine, it can be used to treat viral hepatitis, acute myocardial infarction, it can increase the efficacy of hepatitis B if combined with RNA, it can assist to chemotherapy and prevent thrombosis, it also has effects on reducing blood fat and enhance the body's immune function.
