- in the treatment of thrombotic diseases: deep vein thrombosis, pulmonary artery embolism, unstable angina, acute peripheral arterial embolism;
- in procedures involving extracorporeal circulation and hemodialysis (used to remove toxic substances from the blood in cases of severe kidney function disorders);
- in the diagnosis and treatment of acute and chronic coagulation disorders, such as disseminated intravascular coagulation;
- to flush intravenous catheters and cannulas to ensure their patency before administering intravenous injections.
