Thrombolytic (Fibrinolytic) Agents Flashcards
The central process of _____ is the conversion of inactive plasminogen to the active proteolytic enzyme plasmin.
fibrinolysis
The central process of fibrinolysis is the conversion of inactive ______ to the active proteolytic enzyme _____.
plasminogen; plasmin
All fibrinolytic drugs produce rapid lysis of thrombi by increasing formation of ______ from ______.
plasmin; plasminogen
How does Streptokinase (Streptase) work?
converts uncomplexed plasminogen to active plasmin- Generally results in systemic activation of plasmin
This drug converts uncomplexed plasminogen to active plasmin- Generally results in systemic activation of plasmin.
Streptokinase (Streptase)
How does Tissue Plasminogen Activator (tPA): Alteplase (Activase) work?
binds to fibrin and selectively activates bound plasminogen
This drug binds to fibrin and selectively activates bound plasminogen.
