Clinically, there is no absolute special drug for thrombolysis, and the drugs used for thrombolysis include streptokinase, urokinase, and recombinant tissue-type fibrinogen activator. 1. Streptokinase: It is the earliest fibrinolytic plasminogen activator discovered, because it is secreted by streptococcus, so it is called streptokinase. It can combine with fibrinogen and activate fibrinogen into fibrinolytic enzyme, thus playing the role of thrombolysis. 2. Urokinase: It acts directly on the endogenous fibrinolytic system, activates fibrinolytic enzymes, and degrades fibrin clots, fibrinogen, coagulation factors 5 and 8 in the blood, thus exerting thrombolytic effects. In addition, it can inhibit ADP-induced platelet aggregation and prevent thrombosis. 3. Selective fibrinogen activator: Atipase, which can directly activate fibrinogen into fibrinolytic enzyme and play the role of thrombolysis. Clinically, it is mainly used for intravenous thrombolysis after acute myocardial infarction, acute massive pulmonary embolism and acute ischemic stroke. If you have a thrombus or have symptoms of discomfort, please consult the doctor in time and follow the doctor’s instructions actively to avoid delaying your condition.
