You'll have to ask your competent? doctor why the hell edaravone is approved in Japan since 2001 but not the US. If your doctor doesn't know this off the top of the head; you DON'T have a functioning stroke doctor!
Has your stroke hospital done anything with edaravone in the last decade?

Adjuvant neuroprotective therapies for acute ischemic stroke in the reperfusion era: a comparative narrative review of clinical evidence for edaravone, edaravone-dexborneol, and butylphthalide
Abstract
Reperfusion therapies, including intravenous thrombolysis and endovascular treatment (EVT), are central to acute ischemic stroke (AIS) management; however, ischemia–reperfusion injury may limit recovery despite successful recanalization. This structured narrative review compares the clinical evidence, safety signals, and mechanistic literature for edaravone, butylphthalide (NBP), and the fixed-dose combination edaravone-dexborneol (EDB) as adjunctive neuroprotective approaches. The evidence base is heterogeneous with respect to population, background reperfusion treatment, outcome timing, and geographical setting. In TASTE-2, EDB administered before EVT was associated with a modest increase in 90-day functional independence versus placebo (55.0% vs. 49.6%, p = 0.05), without an apparent safety signal; bridging alteplase was permitted in a subset of participants. In the BAST trial, NBP improved the prespecified 90-day functional outcome versus placebo among patients receiving intravenous thrombolysis and/or EVT (56.7% vs. 44.0%). Observational studies and meta-analyses provide supportive but non-confirmatory evidence for edaravone. Network meta-analyses generate relative rankings at individual endpoints, but indirect comparisons and differing outcome networks preclude definitive between-agent selection. Mechanistic studies indicate overlapping antioxidant, anti-inflammatory, mitochondrial, and neurovascular effects rather than exclusive pathway regulation. Biomarker and imaging approaches, including exploratory GFAP and UCH-L1 measurements, are promising research tools but are not yet validated for treatment selection in AIS. Accordingly, these agents should be regarded as candidates for further evidence-informed adjunctive use; future trials are needed to define reproducible patient-selection and treatment-timing strategies.
