Pharmacia and upjohn co, Ferring pharmaceuticals as • Taken orally, tranexamic acid is indicated for the treatment of hereditary angioedema, cyclic heavy menstrual bleeding in premenopausal females, and other instances of significant bleeding in the context of hyperfibrinolysis. Given intravenously, tranexamic acid is indicated for short-term use (2-8 days) in patients with hemophilia to prevent or reduce bleeding following tooth extraction.
Tranexamic acid is an antifibrinolytic used to reduce or prevent hemorrhagic episodes, especially in the context of hyperfibrinolytic disorders.
Tranexamic acid competitively and reversibly inhibits the activation of plasminogen via binding at several distinct sites, including four or five low-affinity sites and one high-affinity site, the latter of which is involved in its binding to fibrin. The binding of plasminogen to fibrin induces fibrinolysis - by occupying the necessary binding sites tranexamic acid prevents this dissolution of fibrin, thereby stabilizing the clot and preventing hemorrhage.
