TY - JOUR T1 - ACute stroke therapy at the crossroads AU - Broderick JP, Meyers PM Y1 - 2011/11/09 N1 - 10.1001/jama.2011.1622 JO - JAMA SP - 2026 EP - 2028 VL - 306 IS - 18 N2 - Intravenous tissue plasminogen activator (IV t-PA) is the only treatment approved by the Food and Drug Administration (FDA) that was proven clinically effective in multiple randomized clinical trials for acute ischemic stroke.1 The effectiveness of t-PA is time-dependent; treatment beyond 4.5 hours from stroke onset does not result in improved clinical outcome.1 By reducing long-term disability, IV t-PA is also highly cost-effective.2 No other treatment for acute ischemic stroke has shown greater clinical efficacy than IV t-PA.
