Inaccurate description of medication The method of thrombolytic therapy is the use of drugs to dissolve the thrombus for the purpose of revascularization, thereby regaining the supply of blood oxygen to the area of obstructed vascular perfusion. Since fibrin is an important component of blood clots, thrombolytic therapy is currently performed mainly with fibrinolytic drugs, including streptokinase, urokinase, and tissue-type fibrinogen activator. The specific method is that streptokinase converts fibrinogen into active fibrinase and dissolves the thrombus. The commonly used dose is 500,000 units in saline or 5% glucose in 100 ml intravenously over 30 minutes, with a maintenance dose of 50,000-100,000 units per hour until the thrombus dissolves or the disease no longer progresses, usually for 12 hours to 5 days. Because of the antigenic and thermogenic effects of streptokinase, significant side effects are often seen after use.
