Quick Summary

Fibrinolysis is the enzymatic breakdown of fibrin. Fibrin is a protein that forms the major component of a blood clot, produced from fibrinogen in response to bleeding. Fibrinolysin, also known as plasmin, is an enzyme that promotes the dissolution of blood clots.1234

The human body has a natural fibrinolytic system that helps dissolve clots as wounds heal. This system degrades fibrin and fibrinogen, with plasmin being the active enzyme. Fibrinolytic drugs work by activating this pathway to stimulate clot dissolution, distinguishing them from anticoagulants which prevent clot formation.5

…fibrin itself is dissolved (fibrinolysis) by an enzyme, plasmin. The fibrin clot is replaced by a permanent framework of scar tissue that includes collagen, and healing is thus complete.
