Edaravone (Radicut) is a neuroprotective agent used for the purpose of aiding neurological recovery following acute brain ischemia and subsequent cerebral infarction.[1] It acts as a potent antioxidant and strongly scavenges free radicals, protecting against oxidative stress and neuronal apoptosis.[2][3][4] It has been marketed solely in Japan by Mitsubishi Pharma since 2001.[1] and marketed in India by Edinburgh Pharmaceuticals by the brand name Arone

Edaravone has been shown to attenuate methamphetamine- and 6-OHDA-induced dopaminergic neurotoxicity in the striatum and substantia nigra, and does not affect methamphetamine-induced dopamine release or hyperthermia.[5][6] It has also been demonstrated to protect against MPTP-mediated dopaminergic neurotoxicity to the substantia nigra, though notably not to the striatum.[7][8][9]
