Ulinastatin is widely used in medical settings for its anti-inflammatory and anti-protease properties. It is commonly administered to treat conditions such as acute pancreatitis, where it helps reduce inflammation and protect pancreatic tissue. Additionally, it is used in managing sepsis and septic shock by modulating the immune response and inhibiting excessive cytokine release. Ulinastatin is also employed during surgeries, particularly cardiac and liver surgeries, to minimize organ damage caused by ischemia-reperfusion injury. Its ability to stabilize cell membranes and inhibit enzymes like trypsin and elastase makes it valuable in treating acute respiratory distress syndrome (ARDS) and other inflammatory lung conditions. Furthermore, it has shown potential in improving outcomes in patients with severe trauma or burns by reducing systemic inflammation and organ dysfunction.
