What is the mechanism of the action of aprotinin?
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.

Loading Dose: The loading dose of Trasylol® (aprotinin) should be given intravenously to patients in the supine position over a 20-30 minute period. Rapid intravenous administration of Trasylol® (aprotinin) can cause a transient fall in blood pressure (see DOSAGE AND ADMINISTRATION).
Why was aprotinin withdrawn from the market?
The strong and consistent negative mortality trend seen with aprotinin led the investigators to suggest that its use in high-risk cardiac surgery was unwarranted despite its potential for reducing massive bleeding. Shortly after the end of the trial, Bayer voluntarily withdrew aprotinin from the market.
