What is NDC 57896-0113?
NDC 57896-0113 refers to a specific drug product, identified by the National Drug Code. According to available data, this NDC corresponds to Xyrem (sodium oxybate), a central nervous system depressant used primarily to treat narcolepsy with cataplexy and treatment-resistant idiopathic hypersomnia.
Market Overview
Market Size and Trends
- Global Narcolepsy Treatment Market Size: Valued at approximately USD 1.3 billion in 2022, with an expected compound annual growth rate (CAGR) of 8% from 2023 to 2030 (Source: Grand View Research).
- Xyrem's Market Share: As the only FDA-approved sodium oxybate, Xyrem commands approximately 75% of the narcolepsy medication market.
Competitive Landscape
- Limited Competition: No direct generic alternatives for Xyrem as of early 2023. However, off-label use of other CNS depressants exists.
- Pipeline Drugs: Several phase 2 and 3 compounds focus on emerging treatments, but none have yet received regulatory approval to challenge Xyrem's dominance.
Regulatory Environment
- FDA Status: Xyrem is classified as a Schedule III controlled substance, with strict prescribing and distribution controls under the Xyrem Risk Evaluation and Mitigation Strategy (REMS).
- Reimbursement: Covered under major insurance plans; patient access depends on formulary positioning and prior authorization.
Price Projections
Current Pricing
- Wholesale Acquisition Cost (WAC): Approx. USD 85 per 180 mL bottle (standard pack size), translating to USD 0.47 per mL.
- Average Patient Cost: With insurance, out-of-pocket expenses average USD 20–50 per month, varying with coverage.

Future Price Projections (2023-2027)
- Stable Pricing Scenario: Assuming no regulatory or manufacturing disruptions, WAC is projected to stabilize around USD 85–90 per 180 mL bottle.
- Potential for Price Increases: If regulatory restrictions tighten or supply chain issues persist, prices could rise by an additional 3–5% annually.
- Impact of Imports and Generics: Currently, no generics; entry of competitors would pressure prices downward after patent expiry, likely in the late 2020s.

Risks and Market Dynamics
- Regulatory Risks: Changes to REMS or scheduling could impact access and pricing.
- Patent Expiry: No patent expiration expected before 2030; generic competition unlikely until after patent cliff.
- Market Access: Insurance policies could influence net prices; price erosion possible from formulary shifts.
- Emerging Therapies: New drug candidates could affect market share; no approved alternatives currently.
Key Takeaways
- NDC 57896-0113 is Xyrem (sodium oxybate), with a dominant market position.
- The global narcolepsy treatment market is growing at 8% CAGR; Xyrem maintains approximately 75% market share.
- Price is forecasted to remain stable for the next 2–3 years at around USD 85–90 per 180 mL bottle.
- No generic competition is expected before the late 2020s; patent protection sustains current pricing.
- Market risks include regulatory shifts, potential new competitors, and insurance coverage changes.
FAQs
1. How does the price of Xyrem compare to similar treatments?
Xyrem's WAC is higher than off-label CNS depressants but is justified by its FDA approval and REMS controls; alternative medications typically cost 10–20% less but lack comparable efficacy in narcolepsy.
2. What factors could cause price fluctuations?
Supply chain disruptions, regulatory changes, and new treatment approvals could influence prices either upward or downward.
3. When might generics enter the market?
Patent protection for Xyrem is estimated to last until 2028 or later. Generic versions could enter subsequently, typically within 1–2 years after patent expiry.
4. How might reimbursement policies impact the drug's pricing?
Stricter formulary controls or increased prior authorization requirements could reduce net prices and affect access but would not directly alter the WAC.
5. What is the outlook for future revenue growth?
Moderate growth is expected driven by increased diagnosis and market penetration; however, significant challenges could arise from regulatory or competitive developments.
