In medicine, tranexamic acid a hemostatic agent approved for hemorrhaging in hemophilia, with unapproved uses in cyanide poisioning, hereditary angioedema, hyperfibrinolysis induced hemorrhage, postsurgical hemorrhage and prevention of hemorrhage from cardiovascular instability after coronary artery bypass graft. It is an "inhibitor of plasminogen activation, and at much higher concentrations, a noncompetitive inhibitor of plasmin, i.e., actions similar to aminocaproic acid." It is similar to, but more potent than aminocaproic acid. It is also used to treat acquired angioedema due to deficiency of complement C1 inhibitor protein.

Mechanism of Action

At low concentration, tramexamic acid, which binds to the kringle domain of plasminogen, is a competetive inhibitor of plasminogen activation into plasmin (fibrinolysin), an enzyme that degrades fibrin clots, fibrinogen, and procoagulant plasma proteins such as factor V and factor VIII. At higher concentrations it is a noncompetetive inhibitor of plasmin. It binds to the strong and weak receptor sites of plasminogen with affnities about 10 times greater than aminocaproic acid.
