Reduce thrombosis. Thrombosis is a process in which a series of plasma coagulation factors are enzymatically hydrolyzed and activated, and finally thrombin is generated, which in turn generates fibrin clots. New small molecule anticoagulant drugs target certain coagulation factors or thrombin during the coagulation process to inhibit or destroy their activity, thereby destroying a link in the coagulation process to inhibit blood clotting and thrombosis. Thrombin inhibitors currently used are indirect thrombin inhibitors and direct thrombin inhibitors. The aforementioned heparin drugs and coumarin drugs are the most common indirect thrombin inhibitors in clinical practice.

Reduces thrombosis. Thrombosis is the process of enzyme solution and activation of a series of plasma clotting factors, which eventually produces coagulation enzymes, which in turn produce fibrin clots. The new small molecule anticoagulant drug is to target certain coagulation factors or coagulation enzymes in the clotting process, inhibit or destroy its activity, thus destroying a certain part of the clotting process to inhibit blood clotting and thrombosis. Currently used clotting enzyme inhibitors are indirect clotting enzyme inhibitors and direct clotting enzyme inhibitors. The aforeid heparin-based drugs and coumarin drugs are the most common indirect clotting inhibitors in the clinic today.

Reduce thrombosis. Thrombus formation is a process of enzymatic hydrolysis and activation of a series of plasma clotting factors, which eventually generates thrombin and fibrin clot. The new small molecule anticoagulant drugs take some coagulation factors or thrombin in the process of coagulation as the target, inhibit or destroy its activity, thus destroy a link in the process of coagulation to inhibit blood coagulation and thrombosis. At present, indirect thrombin inhibitors and direct thrombin inhibitors are used. Heparins and coumarins mentioned above are the most common indirect thrombin inhibitors in clinic<br>
