This product is a non-peptide endothelin receptor antagonist, which can antagonize endothelin-induced vasoconstriction, blood pressure increase and vascular smooth muscle cell proliferation, reduce vascular endothelial damage; increase NO synthesis, relax vascular smooth muscle; inhibit platelet aggregation, anti-coagulation, and improve blood rheology characteristics. This product can also inhibit cholesterol synthesis, lower blood lipids, scavenge free radicals, prevent lipid peroxidation damage; affect complement, enhance immune function, and have certain analgesic and antispasmodic effects.

1. It can obviously inhibit the synthesis of thromboxane A2 (TXA2), counteract the platelet aggregation caused by arachidonic acid (AA), and has a stronger and faster antiplatelet aggregation effect than aspirin (ASP). 2. It can enhance the fibrinolytic activity and promote the dissolution of thrombus. 3. It can reduce the specific viscosity of whole blood and plasma, and accelerate the electrophoresis of red blood cells. 4. It can relax the vascular smooth muscle, dilate the artery, and increase the blood flow of the coronary artery and cerebral artery. 5. It can improve the ability to resist hypoxia. 6. It can strongly scavenge free radicals. 7. It can inhibit the inflammatory exudation of capillaries.

This drug is an immune enhancement drug. It is a polynucleotide peptide (molecular weight less than 5000) extracted from healthy human blood or animal spleen. It is not easily destroyed by RNAse, DNAse and trypsin. This drug is an important factor in cellular immune response. It has no antigenicity and is not an antibody fragment, but it can transmit the cellular immune reactivity of multiple antigens, including bacteria, fungi, viruses, tissue compatibility antigens and tumor-specific antigens, etc. It can enhance the immune reactivity of receptor cells, promote the chemotaxis of macrophages, increase delayed cell response, and improve the body's ability to kill tumors.
