Recombinant Albumin-free Streptokinase in Acute Myocardial Infarction: Pharmacovigilance Study (TIMES)
Keywords:
streptokinase, thrombolysis, pharmacovigilance, acute myocardial infarctionAbstract
Introduction: Acute myocardial infarction represents a public health problem in Cuba; it constitutes the main cause of morbidity and mortality. Fibrinolytic therapy with Heberkinase (recombinant streptokinase) has been effective and safe for this disease. The Center of Genetic Engineering and Biotechnology of Cuba developed a new formulation of recombinant streptokinase without albumin, to avoid the use of this hemoderivative.
Objective: To evaluate the safety of recombinant albumin-free streptokinase in the treatment of acute myocardial infarction under conditions of routine medical practice.
Methods: A pharmacovigilance and multicenter study was performed; the method of active monitoring during treatment and voluntary reporting was used. The protocol followed the guidelines of the Declaration of Helsinki. Adult patients who met the diagnostic and selection criteria were included and received 1,500,000 IU of recombinant albumin-free streptokinase intravenously. The information requested included: type of adverse event, duration, severity, outcome and causal relationship. A quantitative pharmacovigilance algorithm was applied to establish the degree of imputability. The proportion of each adverse reaction in the studied population was calculated.
Results: 213 patients were reported; 43.7% (93) with adverse events. The most frequent events were: arterial hypotension (30.0%), nausea (14.6%), vomiting (11.7%) and arrhythmias (6.1%). Eight patients died, whose causes were established to be of cardiac origin.
Conclusions: Thrombolysis with recombinant albumin-free streptokinase in acute myocardial infarction was safe and effective, with reduced mortality and associated complications.
