[Thrombolytic therapy of ischemic stroke].

Reperfusion therapy is one of the main treatment strategies of ischemic stroke. The first studies of the efficacy of thrombolytic medications started form the use of streptokinase and fibrinolysin in patients with ischemic stroke in late 50 - early 60 of the XX century in the United States, Soviet Union, and Western Europe. After the development of recombinant tissue plasminogen activator, thrombolysis became one of the main methods of reperfusion in patients with acute ischemic stroke, acute myocardial infarction, or other acute vascular thrombotic events. Later, modified variants of tissue plasminogen activator with prolonged clearance time, high fibrin-selectivity, and bolus delivery were introduced. Another group of thrombolytic agents includes derivatives of flora and fauna - external plasminogen activators, of which streptokinase, staphylokinase, and desmoteplase are most common drugs. These medications are not a structural part of the human organism, and overcoming of immunogenicity while preserving fibrinolytic activity and fibrin specificity is one of the main tasks in applying them in clinical practice.
