Edaravone tau muag hauv Nyij Pooj rau kev txhim kho kev mob hlwb rov qab los tom qab lub paj hlwb raug mob. Tam sim no, ntau tus neeg sawv cev cais ua neuroprotectants thiab ua los ntawm cov txheej txheem sib txawv (txwv tsis pub glutamate tso tawm, thaiv cov calcium raws, lazaroids) tau ua lag luam rau kho cov txiaj ntsig ntawm lub paj hlwb puas vim raug mob, ischemia lossis plawv nres. Edavarone yog thawj qhov tshuaj tiv thaiv kab mob nrog dawb radical scavenging kev ua haujlwm los qhia rau cov kab mob no. Qhov no tau piav qhia yav dhau los (tshwj xeeb yog norantipyrine, ib ntawm peb cov tshuaj metabolites ntawm antipyrine hauv tsiaj) tuaj yeem npaj tau yooj yim los ntawm kev hloov pauv ncaj qha ntawm phenylhydrazine nrog alkylacetoacetate. Edarevone yog tus neeg sawv cev lipophilic, nkag tau yooj yim rau cov ntaub so ntswg hauv lub hlwb, uas muaj peev xwm txo qis edema hauv lub hlwb tom qab ischemia los ntawm thaiv cov arachidonic acid cascade ua rau peroxidative neurodegeneration. Qhov txaus siab, tus neeg sawv cev no tau pom tias tua cov pa oxygen uas muaj zog hauv cov cell endothelial homogenate, nrog rau kev tiv thaiv hauv vitro lipid peroxidative kev tawg ntawm daim nyias nyias, yog li ua qhov no ua tau zoo thaum rov ua dua tom qab raug mob ischemic. Raws li qhov qhia ntxiv, theem III kev sim pib nrog edaravone txhawm rau nce txoj hauv kev rov zoo tom qab subarachnoid hemorrhage.
