Heparin sodium API is mainly used for the production of standard heparin preparations and low molecular weight heparin apis, and then low molecular weight heparin preparations. Heparin sodium apis can be subdivided into heparin sodium apis intermediates and refined heparin sodium apis.

　　The purity of Heparin sodium API intermediates is relatively low, which can not be used as standard heparin preparation materials directly. Refined heparin sodium API is relatively pure, and its preparation technology and process are complex. It is used for the preparation and production of standard heparin preparations and low molecular weight heparin API.

　　Effects and efficacy of heparin preparation:

　　1. Treat early disseminated intravascular coagulation complicated with various diseases.

　　2. Prevent arteriovenous thrombosis and pulmonary embolism.

　　3. Treat arteriovenous thrombosis and pulmonary embolism, ischemic stroke, unstable angina pectoris (alleviate symptoms, prevent myocardial infarction), acute myocardial infarction (prevent early reinfarction and infarction area extension, reduce mortality).

　　4, artificial cardiopulmonary, peritoneal dialysis or hemodialysis as anticoagulant drugs.

　　5. As maintenance therapy for thrombolysis therapy.

　　6, used in blood transfusion to prevent blood coagulation and blood bank preservation and other in vitro anticoagulant.
