[0002] Heparin sodium is an anticoagulant that can interfere with many aspects of the blood coagulation process and has an anticoagulant effect both in vivo and in vitro. During the production of heparin sodium, some impurities may be mixed in the heparin sodium. Heparin sodium is filtered because filtration can remove suspended solid particles, impurities and microorganisms, making the heparin sodium solution clearer, purer and safer.
