| Solubility | Freely soluble in water |
| Appearance | neat |
| Physical and Chemical Properties | Heparin calcium in amorphous powder. Insoluble in ethanol, acetone and other organic solvents. Heparin calcium injection is a new subcutaneous injection of heparin sodium, yellow brown sterile aqueous solution. Because the affinity of heparin for Ca2 ion is greater than the affinity for Na ion, when heparin sodium is used, it often causes calcium deposition in different tissues, especially in blood vessels and capillaries, especially in high-dose subcutaneous injection, the chelating effect of calcium destroys the permeability of adjacent capillaries, resulting in petechiae and hematoma. Heparin calcium can avoid the imbalance of blood electrolyte, which may be caused by the process of converting sodium salt to calcium salt. Both with heparin anticoagulant, antithrombotic function, but also stable, rapid, safe, reduce petechiae and hematoma induration. |
| Use | Used as an anticoagulant |
calciumheparin - Nature
Open Data Verified Data
- because heparin has a stronger affinity for Caz than Na, heparin often causes calcium deposition in different tissues, especially in blood vessels and capillaries, especially in high-dose subcutaneous injection, the chelating effect of calcium destroys the permeability of adjacent capillaries, resulting in petechiae and hematoma. Heparin calcium can avoid the imbalance of electrolyte balance in blood which may be caused by the conversion of sodium salt to calcium salt. Both with heparin anticoagulant, antithrombotic function, but also stable, rapid, safe, reduce petechiae and hematoma induration.
- at present, foreign heparin calcium instead of heparin sodium, Japan, Western Europe, the United States, Italy are produced and widely used in clinical.

calciumheparin - Standard
Authoritative Data Verified Data
The calcium salt of aminoglucan sulfate extracted from porcine intestinal mucosa of this strain is a mixture of sugar chains of different molecular weights and is composed of a-D glucosamine (N-sulfated, O-sulfated or N-acetylated) and O-sulfated uronic acid (a-L-iduronic acid or B- D glucuronic acid) are alternately linked to form a polymer, which has the effect of prolonging the blood clotting time. According to the dry product calculation, this product per 1 mg anti factor II a titer of not less than 180IU. The ratio of the titer of anti-X a factor to the titer of anti-II a factor should be between 0.9 and 1.1.
