Aprotinin is a serine protease inhibitor used to reduce the risk for perioperative blood loss and the need for blood transfusion in high-risk patients during cardiopulmonary bypass for coronary artery bypass graft surgery.
Aprotinin inhibits serine proteases including trypsin, chymotrypsin and plasmin at a concentration of about 125,000 IU/mL, and kallikrein at 300,000 IU/mL. The inhibition of kallikrein inhibits formation of factor XIIa. This inhibits the intrinsic pathway of coagulation and fibrinolysis. Inhibition of plasmin also slows fibrinolysis.
For prophylactic use to reduce perioperative blood loss and the need for blood transfusion in patients undergoing cardiopulmonary bypass in the course of coronary artery bypass graft surgery who are at an increased risk for blood loss and blood transfusion.
