BailliÃ¨re's Clinical Haematology. 6 Mechanism of action of the thrombolytic agents. 6 Mechanism of action of the thrombolytic agents JEFFREY I. WEITZ Fibrin formed during the haemostatic, inflammatory or tissue repair process serves a temporary role, and must be degraded to restore normal tissue function and structure.
In plasma thromboplastinogen transforms in thromboplastin, a reaction triggered by tissue and platelet factors released after injury of blood vessel. Thromboplastin then catalyzes along with calcium ions the transformation of the prothrombin in thrombin. Thrombin then catalyzes a reaction which produces fibrin from fibrinogen. Fibrin, as an insoluble substance, precipitates to form a network which traps red blood cells and platelets forming the blood clot and containing hemorrhage.
