Binds to and blocks the activation of plasminogen (PLAT), thus inhibiting the subsequent conversion of fibrin to plasmin (fibrinolysis).
Therapeutic use
To enhance hemostasis of excessive bleeding from fibrinolysis (causes may include cardiac surgery, hematologic disorders, neoplastic disorders, abruption placentae, hepatic cirrhosis and urinary fibrinolysis).
Pregnancy and lactiation implications
Use caution if administered during pregnancy or lactation.
Unlabeled use
Treatment of traumatic hyphema. Control bleeding in thrombocytopenia and in oral bleeding in coagulation disorders. Topical treatment of bleeding associated with dental procedures in patients on oral anticoagulant therapy. Prevention of perioperative bleeding associated with cardiac surgery.
Contraindications
Disseminated intravascular coagulation (without heparin). Active intravascular clotting process.
Warnings and precautions
Intrarenal obstruction may occur secondary to glomerular capillary thrombosis or clots in the renal pelvis and ureters (do not use in hematuria of upper urinary tract origin unless possible benefits outweigh risks). Skeletal muscle weakness has been reported with prolonged use. Caution in renal impairment (may accumulate). Do not administer with factor IX complex concentrates or anti-inhibitor coagulant complexes (risk of thrombosis). Injection contains benzyl alcohol («gasping syndrome» in neonates). Rapid I.V. administration should be avoided.
