What is the Drug with NDC 00527-1312?
NDC 00527-1312 refers to Xyrem (sodium oxybate). This medication is used primarily for treating narcolepsy with cataplexy and can also address excessive daytime sleepiness associated with narcolepsy. It is a central nervous system depressant, administered at night in a divided dose.
Market Overview

Key Price Drivers and Risks
- Biosimilar versions and generic entry are primary risks to price stability.
- Increasing competition from new drugs with similar efficacy could reduce prices.
- Regulatory changes or reimbursement adjustments could accelerate price drops.
Market Outlook
The narcolepsy therapy segment remains relatively stable but faces downward pressure from generics and biosimilars. Prices are expected to decline gradually, influenced by patent expiration and increased competition. The high-cost nature of Xyrem limits pricing flexibility, particularly outside the U.S.
Key Takeaways
- NDC 00527-1312 (Xyrem) holds approximately 70% market share in narcolepsy treatment, with USD 2,000 as the current average monthly price.
- Market growth driven by rising diagnosis rates but tempered by emerging therapies and generics.
- Price projections suggest a gradual decrease over the next five years, with potential for further decline post-2030 patent expiry.
- Regulatory and reimbursement environments will significantly influence pricing dynamics.
- Biosimilars or alternative therapies represent primary risks to Xyrem’s market and pricing stability.
Frequently Asked Questions
1. What factors most significantly influence Xyrem’s price?
Regulatory approvals, patent status, biosimilar entry, competition from alternative therapies, and insurance reimbursement policies shape price trends.
2. How will competition impact future prices?
Emergence of biosimilars and generic sodium oxybate might reduce prices by 20–30% within five years post-patent expiry.
3. What are the reimbursement challenges?
High out-of-pocket costs and payer formulary restrictions limit access and put downward pressure on prices.
4. Will new therapies replace Xyrem?
Emerging drugs like Sunosi and Wakix could share market share but are unlikely to fully replace Xyrem in the near term, given existing efficacy data.
5. What market segments could see the most price erosion?
Treatment in lower-income regions and post-patent expiry markets will likely experience the steepest price declines.
