The mechanism by which edaravone slows the decline of physical function in patients with ALS is unknown. Edaravone is a free radical and peroxynitrite scavenger that prevents oxidative damage to cell membranes and may contribute to inhibiting the progression of ALS (Nagase 2016).


Metabolized to inactive sulfate and glucuronide conjugates; sulfate conjugate formed by sulfotransferases. Glucuronide conjugation involves UGT1A6, UGT1A9, UGT2B7, and UGT2B17 in the liver and kidney.
