The drug gained FDA approval in 2002 and holds a significant market position due to its unique efficacy and controlled substance status.
Market Landscape
Market Size & Growth:
- The global narcolepsy treatment market was valued at approximately $250 million in 2022 and is projected to grow at a CAGR of 8-10% through 2030.
- Xyrem accounts for roughly 65-70% of this market, with annual sales approaching $600 million globally in 2022, per IQVIA data.
Key Competitors:
- JZP-258 (sodium oxybate) formulation by Jazz Pharmaceuticals as a reformulation.
- Off-label treatments such as Modafinil (Provigil) and alternative stimulants, which do not directly compete with Xyrem's indication but impact market dynamics.
Regulatory & Policy Factors:
- Xyrem is classified as a Schedule III controlled substance. Strict distribution controls limit prescriber and pharmacy access.
- Ongoing scrutiny of abuse potential influences pricing and reimbursement decisions.
Pricing Dynamics
