Tranexamic Acid is an antifibrinolytic, blocking lysine-binding sites (LBS) of plasmin and elastase-derived plasminogen fragments, with IC50 value of 5 mM [1].
Plasmin, generated from plasminogen under a reaction catalyzed by urokinase and tissue plasminogen activator, has a well-defined role in fibrinolysis. The LBS on plasmin and plasminogen mediate binding to fibrin and to cell surfaces, thereby enhancing the activation rate of plasminogen [1].
At concentrations of 0, 1, 2, 4, 6, 8, 10 μM, Tranexamic Acid dose-dependently inhibited porcine plasmin-induced neutrophil adherence to endothelial cell monolayers, with IC50 value of 5 mM. The neutrophil adherence inducing effect of plasmin was abolished under the treatment of 10 mM Tranexamic Acid [1].
In a rat bleeding model, where 8 mg/kg/h tissue plasmin activator (tPA) was continuously infused to prolong bleeding time beyond control values, Tranexamic Acid was administered by continuous infusion of 30, 100 mg/kg/h up to a dose of 300 mg/kg/h. Tranexamic Acid at 30 mg/kg/h showed no effects on bleeding, but exhibited a significant reduction in the bleeding time at 100 mg/kg/h, with the greatest effect seen at the highest dose of 300 mg/kg/h [2].
