- Free Radical Scavenger
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.
Urine (70% to 90% as glucuronide conjugate; 5% to 10% as sulfate conjugate; ≤1% unchanged)
Time to Peak
4.5 to 6 hours
92% (mainly albumin)
Use: Labeled Indications
Amyotrophic lateral sclerosis: Treatment of amyotrophic lateral sclerosis (ALS)
Hypersensitivity to edaravone or any component of the formulation
Amyotrophic lateral sclerosis (ALS): IV:
Initial cycle: 60 mg once daily for 14 days, followed by a 14-day drug-free period.
Subsequent cycles: 60 mg once daily for 10 days within a 14-day period, followed by a 14-day drug-free period.
Refer to adult dosing. Use with caution.
Dosing: Renal Impairment
No dosage adjustment necessary. Renal impairment is not expected to affect the exposure to edaravone (has not been studied).
Dosing: Hepatic Impairment
Mild to moderate impairment: No dosage adjustment necessary (has not been studied).
Severe impairment: There are no dosage adjustments provided in the manufacturer's labeling (has not been studied).
IV: For IV use only. Administer as two consecutive 30 mg infusion bags (60 mg total) over 60 minutes (infusion rate: ~1 mg/minute [3.33 mL/minute]). Do not mix edaravone with other medications. Do not use if the oxygen indicator has turned blue or purple before opening. Promptly discontinue with any signs or symptoms consistent with a hypersensitivity reaction.
Store at ≤25°C (77°F); excursions permitted to 15°C to 30°C (59°F to 86°F). Protect from light. Once overwrap package is opened, use within 24 hours.
There are no known significant interactions.

Concerns related to adverse effects:
• Hypersensitivity: Hypersensitivity reactions (eg, redness, wheals, erythema multiforme) and anaphylaxis have been reported. If hypersensitivity occurs, discontinue treatment and monitor.
Dosage form specific issues:
• Sodium bisulfite: May contain sodium bisulfite; use caution in patients with asthma or a sulfite allergy.
Adverse events were observed in some animal reproduction studies.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience headache or skin irritation. Have patient report immediately to prescriber severe dizziness, passing out, shortness of breath, bruising, difficulty walking, or change in balance (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
