Quick Summary

The fibrinolytic system is a natural process in the human body that dissolves blood clots. This system is crucial for wound healing. It works by degrading fibrin, a protein that forms the meshwork of a blood clot, and fibrinogen, its soluble precursor. The active enzyme in this process is plasmin, which is formed from plasminogen. Plasmin's primary function is to break down fibrin, thereby dissolving the clot. This process is distinct from anticoagulation, which prevents clot formation. Fibrinolytic drugs are designed to activate this system to break down existing clots.12

Chemical mediators of inflammation
kinins, coagulation factors, and the fibrinolytic system—that generate various mediators of inflammation. Activated complement proteins serve as chemotactic factors for neutrophils, increase vascular permeability, and stimulate the release of histamine from mast cells. They also adhere to the surface of bacteria, making them easier targets for phagocytes. The kinin system,…
