Anticoagulant therapy (1) Heparin: Heparin is a commonly used anticoagulant and is a highly sulfated glucosaminoglycan. Heparin is widely found in mammalian tissues, and mast cells are the main producing sites. The main sources of medicinal heparin are bovine lung and pig intestinal mucosa. Heparin used clinically is called unfraction heparin (UFH) because it is a mixture of components with different relative molecular weights. The relative molecular weight is between 33,000 and 30,000, which is also called standard heparin (SH). The drug name is heparin sodium. (2) Low molecular weight heparin: crude heparin is cracked into some fraction with relative molecular mass of 1000 ~ 12000 by chemical or enzymatic hydrolysis methods, and then purified. There are at least 10 kinds of low molecular weight heparin prepared by different manufacturers and different methods.First, Cat5 is referred to as Category 5 and Cat6 is referred to as Category 6.
