🩺 Clinical
Edaravone is used to treat amyotrophic lateral sclerosis (ALS, Lou Gehrig's disease; a condition in which the nerves that control muscle movement slowly die, causing the muscles to shrink and weaken). Edaravone is in a class of medications called antioxidants. It may work to slow the nerve damage associated with the worsening of ALS symptoms.

⏳ Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

⛔ Contraindications ▾
4 CONTRAINDICATIONS RADICAVA and RADICAVA ORS are contraindicated in patients with a history of hypersensitivity to edaravone or any of the inactive ingredients in this product. Hypersensitivity reactions and anaphylactic reactions have occurred [see Warnings and Precautions (5.1 , 5.2) ]. Patients with a history of hypersensitivity to edaravone or any of the inactive ingredients in RADICAVA and/or RADICAVA ORS ( 4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Hypersensitivity Reactions: Advise patients to seek immediate medical care ( 5.1 ) Sulfite Allergic Reactions: RADICAVA and RADICAVA ORS contain sodium bisulfite, which may cause allergic type reactions, including anaphylactic symptoms and asthmatic episodes in susceptible people ( 5.2 )
5.1Hypersensitivity Reactions Hypersensitivity reactions (redness, wheals, and erythema multiforme) and cases of anaphylaxis (urticaria, decreased blood pressure, and dyspnea) have been reported in spontaneous postmarketing reports with RADICAVA. Patients should be monitored carefully for hypersensitivity reactions. If hypersensitivity reactions occur, discontinue RADICAVA and/or RADICAVA ORS, treat per standard of care, and monitor until the condition resolves [see Contraindications (4) ].
5.2Sulfite Allergic Reactions RADICAVA and RADICAVA ORS contain sodium bisulfite, a sulfite that may cause allergic type reactions, including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in susceptible people. The overall prevalence of sulfite sensitivity in the general population is unknown. Sulfite sensitivity occurs more frequently in asthmatic than non-asthmatic people.
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following serious adverse reactions are described elsewhere in the labeling: Hypersensitivity Reactions [see Warnings and Precautions (5.1) ] Sulfite Allergic Reactions [see Warnings and Precautions (5.2) ] Most common adverse reactions (at least 10% of patients treated with RADICAVA and greater than placebo) are contusion, gait disturbance, and headache ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Shionogi Inc. at 1-888-292-0058 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In randomized, placebo-controlled trials, 184 patients with ALS were administered RADICAVA 60 mg in treatment cycles for 6 months. The population consisted of Japanese patients who had a median age of 60 years (range 29-75) and were 59% male.
Most (93%) of these patients were living independently at the time of screening. Most Common Adverse Reactions Observed During Clinical Studies Table 2 lists the adverse reactions that occurred in ≥2% of patients in the RADICAVA-treated group and that occurred at least 2% more frequently than in the placebo-treated group in randomized placebo-controlled ALS trials. The most common adverse reactions that occurred in ≥10% of RADICAVA-treated patients were contusion, gait disturbance, and headache.
Table 2: Adverse Reactions from Pooled Placebo-Controlled Trials Pooled placebo-controlled studies include two additional studies with 231 additional patients, all using the same treatment regimen [see Clinical Studies (14) ]. that Occurred in ≥2% of RADICAVA -Treated Patients and ≥2% More Frequently than in Placebo Patients Adverse Reaction RADICAVA (N=184) % Placebo (N=184) % Contusion 15 9 Gait disturbance 13 9 Headache 10 6 Dermatitis 8 5 Eczema 7 4 Respiratory failure, respiratory disorder, hypoxia 6 4 Glycosuria 4 2 Tinea infection 4 2 Additional Adverse Reactions with RADICAVA ORS In an open-label study in patients with ALS (n=185) treated with RADICAVA ORS for 6 months, fatigue was observed in 7.6% of patients.
6.2Postmarketing Experience The following adverse reactions have been identified during postapproval use of RADICAVA. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Skin and subcutaneous tissue disorders: Hypersensitivity reactions and anaphylaxis [see Warnings and Precautions (5.1 , 5.2) ].
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data, may cause fetal harm. ( 8.1 )
8.1Pregnancy Risk Summary There are no adequate data on the developmental risk associated with the use of RADICAVA or RADICAVA ORS in pregnant women. In animal studies, administration of edaravone to pregnant rats and rabbits resulted in adverse developmental effects (increased mortality, decreased growth, delayed sexual development, and altered behavior) at clinically relevant doses. Most of these effects occurred at doses that were also associated with maternal toxicity (see Animal Data ).
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. The background risk for major birth defects and miscarriage in patients with ALS is unknown. Data Animal Data In rats, intravenous administration of edaravone (0, 3, 30, or 300 mg/kg/day) throughout the period of organogenesis resulted in reduced fetal weight at all doses.
In dams allowed to deliver naturally, offspring weight was reduced at the highest dose tested. Maternal toxicity was also observed at the highest dose tested. There were no adverse effects on reproductive function in the offspring.
A no-effect dose for embryofetal developmental toxicity was not identified; the low dose is less than the recommended human dose of 60 mg for RADICAVA on a body surface area (mg/m 2 ) basis. In rabbits, intravenous administration of edaravone (0, 3, 20, or 100 mg/kg/day) throughout the period of organogenesis resulted in embryofetal death at the highest dose tested, which was associated with maternal toxicity. The higher no-effect dose for embryofetal developmental toxicity is approximately 6 times the recommended human dose (RHD) for RADICAVA on a body surface area (mg/m 2 ) basis.
The effects on offspring of edaravone (0, 3, 20, or 200 mg/kg/day), administered by intravenous injection to rats from GD 17 throughout lactation, were assessed in two studies. In the first study, offspring mortality was observed at the high dose and increased activity was observed at the mid and high doses. In the second study, there was an increase in stillbirths, offspring mortality, and delayed physical development (vaginal opening) at the highest dose tested.
Reproduction function in offspring was not affected in either study. Maternal toxicity was evident in both studies at all but the lowest dose tested. The no-effect dose for developmental toxicity (3 mg/kg/day) is less than the RHD on a mg/m 2 basis.
Reproductive and developmental toxicology studies of edaravone using the oral route have not been conducted.
8.2Lactation Risk Summary There are no data on the presence of edaravone in human milk, the effects on the breastfed infant, or the effects of the drug on milk production. Edaravone and its metabolites are excreted in the milk of lactating rats. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for RADICAVA and RADICAVA ORS and any potential adverse effects on the breastfed infant from RADICAVA and RADICAVA ORS or from the underlying maternal condition.
8.4Pediatric Use Safety and effectiveness of RADICAVA or RADICAVA ORS in pediatric patients have not been established.
8.5Geriatric Use Of the 184 patients with ALS who received RADICAVA in 3 placebo-controlled clinical trials, a total of 53 patients were 65 years of age and older, including 2 patients 75 years of age and older. No overall differences in safety or effectiveness were observed between these patients and younger patients, but greater sensitivity of some older individuals cannot be ruled out.

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action The mechanism by which RADICAVA and RADICAVA ORS exert their therapeutic effect in patients with ALS is unknown.
12.2Pharmacodynamics Cardiac Electrophysiology At exposures at least 5 times higher than that of the recommended doses of RADICAVA and RADICAVA ORS, edaravone does not prolong the QT interval to any clinically relevant extent.
12.3Pharmacokinetics RADICAVA is administered by IV infusion. The maximum plasma concentration (C max ) of edaravone was reached by the end of infusion. There was a trend of more than dose-proportional increase in area under the concentration-time curve (AUC) and C max of edaravone.
With multiple-dose administration, edaravone does not accumulate in plasma. RADICAVA ORS administered orally at the dose of 105 mg, under fasted conditions, was shown to demonstrate an equivalent AUC with RADICAVA (60 mg administered intravenously for 60 min) and C max not less than that of RADICAVA. RADICAVA ORS demonstrated similar pharmacokinetics following administration via feeding tubes and oral administration.
In healthy subjects, RADICAVA ORS does not accumulate with once-daily administration, and the maximum plasma concentration (C max ) and area under the concentration-time curve (AUC) of edaravone is more than dose-proportional over the dose range of 30 to 300 mg (approximately 0.3 and 3 times the recommended dosage, respectively). Absorption RADICAVA ORS has a median time to maximum concentration (T max ) occurring at approximately 0.5 hour (range, 0.25 to 0.75 hours) after fasted oral administration. The absolute oral bioavailability is about 57% because of first-pass effect when comparing RADICAVA ORS (105 mg oral suspension) and RADICAVA (60 mg intravenous formulation).
Effect of Food Following oral administration of RADICAVA ORS to healthy subjects 1 hour before or 8 hours after high-fat meals (800-1000 calories, 50% fat), 4 hours after low-fat meals (400-500 calories, 25% fat), or 2 hours after caloric supplement (250 calories, e.g., protein drink), the C max and AUC did not decrease significantly (less than 20% and 10% changes in C max and AUC, respectively) [see Dosage and Administration (2.3) ] . Following oral administration of RADICAVA ORS to healthy subjects, the C max decreased by 82%, and the AUC decreased by 61% with a high-fat meal compared to fasted conditions.
Following administration of RADICAVA ORS 4 hours after high-fat meals, the C max and AUC decreased by 44% and 24%, respectively. Following administration of RADICAVA ORS 2 hours after low-fat meals, the C max and AUC decreased by 45% and 21%, respectively. Distribution Edaravone is bound to human serum proteins (92%), mainly to albumin, with no concentration dependence in the range of 0.1 to 50 micromol/L.
Edaravone has a mean volume of distribution after intravenous administration of
63.1L. Elimination The mean terminal elimination half-life of edaravone is approximately 4.5 to 9 hours. The half-lives of its metabolites are 3 to 6 hours. Following intravenous administration, the total clearance of edaravone is estimated to be
35.9L/h. Metabolism Edaravone is metabolized to a sulfate conjugate and a glucuronide conjugate, which are not pharmacologically active. The glucuronide conjugation of edaravone involves multiple uridine diphosphate glucuronosyltransferase (UGT) isoforms (UGT1A1, UGT1A6, UGT1A7, UGT1A8, UGT1A9, UGT1A10, UGT2B7, and UGT2B17).
In human plasma, edaravone is mainly detected as the sulfate conjugate, which is presumed to be formed by sulfotransferases. RADICAVA ORS results in 1.3- and 1.7-fold higher exposures for both sulfate and glucuronide metabolites, respectively, when compared to RADICAVA because of first-pass metabolism. Excretion In Japanese and Caucasian healthy volunteer studies, edaravone was excreted mainly in the urine as its glucuronide conjugate (60-80% of the dose up to 48 hours).
Approximately 6-8% of the dose was recovered in the urine as the…
