Heparin is an anionic sulfated aminoglucan. It is a heterogeneous substance with an average molecular weight of 12 000 and exists on the surface of many main cells. Commercial heparin sodium was extracted from pig intestines or cattle lungs. Heparin is composed of non branched low sugar chains with different lengths. D-glucosamine and D-glucuronic acid (or l-iduronic acid) are linked by glycosidic chains to form the basic disaccharide repeat of heparin chain. There are many substitutions in the repeated disaccharide sequence. It includes: R1: H or - oso3 group, R2: SO3 or - coch3 group, so that a few disaccharides form pentose sequence. The molecular weight of heparin is 3-30kda (most chains are 13-15kda).

Heparin combined with the following drugs can increase the risk of bleeding: coumarin and its derivatives, aspirin and non steroidal anti-inflammatory analgesics, dipyridamole, dextran, adrenocortical hormone, adrenocorticotropic hormone, tissue plasminogen activator, urokinase, streptokinase, etc.

The current situation is still very serious. As pharmacuetical manufacturers, it is our mission and worth to work with doctors to provide drug ensurance for the epidemic areas. Coordinating with the government departments, we areseeking the permission of start-working of finished dosage section. We will strictly implement staff safety precautions in accordance with government’s requirements, and make our best efforts to provide anti-coronavirus drug support to the epidemic areas to achieve an early victory against the epidemic.
