Description

Aprotinin is a polypeptide that exhibits anti-fibrinolytic (pro-coagulant) activity. Aprotinin inhibits serine proteases such as trypsin, chymotrypsin, plasmin, and kallikrein. Inhibiting these proteases prevents formation of Factor XIIa and prevents breakdown of blood clots. Aprotinin is clinically used during surgeries to prevent bleeding.
