Tranexamic acid

In medicine, tranexamic acid 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 an "antifibrinolytic hemostatic used in severe hemorrhage." It is also used to treat acquired angioedema due to deficiency of complement C1 inhibitor protein.
