Low molecular weight heparin sodium salt is from chitterlings mucosa of heparin benzyl ester derivatives by alkaline solution poly. Most of composition in its main chain of side has a 4 - enopyranose uronate structure; 15% ~ 15% of the components in the main chain of side has a structure of 1, 6 dehydration. Average molecular weight between 3800 ~ 5000, characteristic value of about 4500. The sulfuric acid salinization degree for each disaccharide unit about 2 sulfuric acid root.
Carnot heparin is a specialized low-molecular-weight heparin fraction derived via enzymatic depolymerization of standard unfractionated heparin. This process enhances bioavailability while reducing bleeding risks. The core structure retains the pentasaccharide sequence essential for antithrombin III activation.
Strictly contraindicated in active major bleeding, severe thrombocytopenia, or recent CNS/spinal surgery. Store at controlled room temperature (20-25°C) away from direct light to maintain stability. Monitor anti-Xa levels regularly in renal impairment cases.
