1.Heparin sodium is white or white powder, tasteless, hygroscopic, soluble in water, insoluble in ethanol, acetone and other organic solvents. It has a strong negative charge in aqueous solution and can combine with some cations to form molecular complexes. The aqueous solution is stable at a pH of 7.
2. Heparin sodium interferes with many of the steps of blood coagulation, and has anticoagulant effects in and out of the body. Its mechanism is complex, mainly through and antithrombin III (AT - III), and enhance the latter to activate II, IX, X, XI and XII the inhibitory effect of clotting factors and its consequences involved in preventing platelet aggregation and destruction, inhibit the formation of blood coagulation activation of enzyme, blocking prothrombin into thrombin, inhibition of thrombin, thereby preventing fibrinogen to fibrin, which play a role of anticoagulation.
