NDC 51672-1273 is the code assigned to a specific pharmaceutical product. The NDC (National Drug Code) indicates the manufacturer, product, and packaging details. Based on the code, the drug is identified as Riluzole, used primarily in the treatment of amyotrophic lateral sclerosis (ALS).
- Manufacturer: MGI PHARMA, INC.
- Formulation: 50 mg capsules
- Packaging: 60 capsules per bottle
Market Landscape
Current Market Size
Riluzole holds a niche market within the ALS treatment space. Market reports from IQVIA and Evaluate Pharma estimate the global ALS drug market at approximately $400 million in 2022. Riluzole accounts for roughly 70-80% of this market, with annual sales close to $280 million.
Competitive Environment
Market competition involves:
- Riluzole (Brand/Generics): Original brand "Rilutek" dominates early treatment phases; generics entered the market in 2018.
- Emerging Therapies: Talents like edaravone (Radicava) gained approval, capturing part of the ALS market.
- Pipeline drugs: Several experimental compounds target neuroprotection or regeneration, but none have achieved significant market penetration yet.
Regulatory Status
- Approved by FDA since 1995 for ALS.
- Generic versions approved post-2018, leading to price erosion.
- Orphan drug designation offers market exclusivity until 2023-2025 in certain regions.
