Used as a serine protease inhibitor, particularly in the management of acute pancreatitis. It helps reduce inflammation by inhibiting enzymes such as thrombin, plasmin, and complement factors. Commonly administered intravenously in clinical settings to prevent complications during procedures like endoscopic retrograde cholangiopancreatography (ERCP). Also utilized in some countries to prevent postoperative pancreatitis and to manage disseminated intravascular coagulation (DIC) associated with severe infections or trauma. Its rapid action and short half-life make it suitable for controlled therapeutic use.
