Tenecteplase for Acute Ischemic Stroke Treatment
Semin Neurol DOI: 10.1055/s-0040-1722722The introduction of thrombolytic therapy in the 1990s has transformed acute ischemic stroke treatment. Thus far, intravenous recombinant tissue plasminogen activator (rt-PA) also known as alteplase is the only thrombolytic proven to be efficacious and approved by the United States Food and Drug Administration. But the thrombolytic agent tenecteplase (TNK) is emerging as a potential replacement for rt-PA. TNK has greater fibrin specificity, slower clearance, and higher resistance to plasminogen activator inhibitor-1 than rt-PA. Hence, TNK has the potential to provide superior lysis wi...

Relevance of the Updated Food and Drug Administration Alteplase Label for Acute Ischemic Stroke: The Estimated Impact and Current Guidelines.
Abstract In 2015, the Food and Drug Administration updated the contraindications for the use of alteplase in acute ischemic stroke (AIS), potentially creating a greater impact on treatment. A history of intracranial hemorrhage and recent stroke within 3 months were removed as contraindications, increasing the number of patients eligible for alteplase. The aim of this commentary is to call attention to the updates and discuss them relative to current American Heart Association/American Stroke Association guidelines. Additionally, we estimate the clinical impact of the updates by analyzing AIS admissions to a large-...

Tissue-type plasminogen activator-binding RNA aptamers inhibiting low-density lipoprotein receptor family-mediated internalisation.
Abstract Recombinant tissue-type plasminogen activator (tPA, trade name Alteplase), currently the only drug approved by the US Food and Drug Administration and the European Medicines Agency for the treatment of cerebral ischaemic stroke, has been implicated in a number of adverse effects reportedly mediated by interactions with the low-density lipoprotein (LDL) family receptors, including neuronal cell death and an increased risk of cerebral haemorrhage. The tissue-type plasminogen activator is the principal initiator of thrombolysis in human physiology, an effect that is mediated directly via localised activation...
