classification of heparin sodium
Heparin sodium, as a commonly used anticoagulant in clinical practice, can not only be added to blood collection vessels to prevent blood clotting, but also be prepared for drug use, effectively preventing thrombosis and reducing the occurrence of cardiovascular and cerebrovascular diseases. According to different preparation methods and structural characteristics, heparin sodium can be divided into various types. Next, we will introduce the classification of heparin sodium in detail.
heparin sodium powder
Classification according to preparation method
1. Natural heparin sodium: A natural product mainly extracted from animal organs such as pig intestines and cow lungs. After complete extraction of heparin, it is finely processed to obtain high-purity heparin sodium raw material. Its production requirements are strict, and it is usually added to the blood collection vessel for use, with relatively stable performance.
2. Synthetic heparin sodium: obtained through chemical synthesis, it has high yield and cost advantages. Currently, polymer method and metal organic compound method are mainly used in the market for synthesis, and its performance and usage are far inferior to the first naturally prepared heparin sodium.
Classification based on structural features
1. Ordinary heparin sodium: Ordinary heparin sodium is a high molecular weight heparin containing multiple repeating units, appearing in the form of a drug. Its anticoagulant effect is good, but its bioavailability is low, and it is prone to side effects. It is rarely used in clinical practice.
2. Low molecular weight heparin sodium: Low molecular weight heparin sodium is a short chain heparin obtained through chemical modification, with high bioavailability and suitable for intravenous injection. Due to its direct contact with the human body, it not only requires high production requirements and expensive prices, but also requires obtaining corresponding certificates before production, and is subject to the supervision of the Medical Commission.
3. Heparin sodium salt: This is a raw material of heparin sodium, mainly extracted from pig intestinal mucosa, and then obtained through ion exchange adsorption. Its average molecular weight is around 15000, and its potency is between 150IU-180IU. It is generally non injection grade, and is prepared into a solution and added to the blood collection vessel as an in vitro anticoagulant.
Classified by purpose
1. Medical heparin sodium: Medical heparin sodium includes the drug heparin sodium and the extracorporeal anticoagulant heparin sodium. Drug use mainly occurs in fields such as cardiac surgery, hemodialysis, and vascular intervention therapy, and has strong anticoagulant and therapeutic effects. The in vitro anticoagulant heparin sodium is mainly used in clinical practice to help blood clot quickly during blood collection and improve the efficiency of medical staff testing.
2. Industrial heparin sodium: This type of heparin sodium is generally low in purity, contains impurities, has low production requirements, and is cheap. It is mainly used in the manufacturing of industrial products such as cellulose and paper.
Different types of heparin sodium have different characteristics and application ranges, and selecting the appropriate type of heparin sodium needs to be considered based on the specific usage. As a professional manufacturer of heparin sodium, Desheng's product type is analytical grade heparin sodium salt, mainly used as an extracorporeal anticoagulant and cannot be used in the human body.
