Tranexamic acid (TXA) is a synthetic antifibrinolytic agent that binds to the lysine binding sites of plasmin and plasminogen. Saturation of the binding sites causes separation of plasminogen from superficial fibrin and hence prevents fibrinolysis. Any surgical procedure can cause a considerable tissue damage and hence trigger the release of enzymes, such as 'tissue plasminogen activator' that converts plasminogen to plasmin and activates fibrinolysis process. TXA can prevent fibrinolysis activity by inhibiting the activity of this enzyme.
