Main Uses
- Clinical Hemostasis: Antifibrinolytic agent for cardiac surgery (CABG), liver transplantation, reducing transfusion needs by 30%–50%
- Acute Pancreatitis: Inhibits trypsin/chymotrypsin activation, prevents pancreatic autodigestion
- Biochemical Research: Protease inhibitor to protect proteins from degradation in Western blotting, enzyme assays
- Anti-inflammatory & Antishock: Inhibits kallikrein, reduces bradykinin production, mitigates inflammation
- Postoperative Adhesion Prevention: Local application reduces fibrin deposition and abdominal/pleural adhesions
