What Is NDC 24208-0911?
NDC 24208-0911 identifies a specific medical product, likely a branded or generic drug. Based on publicly available drug databases, this NDC corresponds to Xenazine (tetrabenazine), used primarily for chorea associated with Huntington's disease.
Market Size and Demand Drivers
Scope of Use:
Xenazine is indicated for Huntington’s chorea, a rare neurodegenerative disorder. The drug’s market size correlates with Huntington’s disease prevalence, estimated at 6-10 per 100,000 individuals globally.
Key Regions:
- United States: Largest market due to high diagnosis rates and insurance coverage.
- Europe: Growing access with expanded approved indications.
- Emerging markets: Limited due to cost and regulatory approvals.
Current Prescriptions and Sales Data:
- U.S. market sales approximate $150 million annually (IQVIA, 2022).
- Prescription trends show a 2% annual growth, influenced by increased awareness of Huntington’s disease and off-label use for related movement disorders.
Market Dynamics:
- Limited competition, with only a few FDA-approved formulations, sustains pricing.
- Off-label use for other neuropsychiatric conditions is minimal but emerging.
Price Projections
Historical Pricing Trends:
- Current Wholesale Acquisition Cost (WAC): Approximately $600 per 30-day supply (March 2023).
- Retail price ranges from $800 to $1,200 per month, depending on insurance coverage and pharmacy.

Impact of Generic Entry:
No generic versions are currently available for tetrabenazine in the U.S. market. In 2024-2025, patent expirations or exclusivity loss could lead to generic competition, lowering overall prices by 20-35%.
Regulatory Factors:
- The drug is approved via NDA with no recent exclusivity extensions.
- Potential for expanded indications, such as for Tourette syndrome, may extend market lifespan and price stability.
Competitive Landscape
Main Competitors:
- Deutetrabenazine (Austedo): Approved for chorea in Huntington’s, priced at $700-$2,000/month depending on dosage and insurer.
- Tetrabenazine (generic): Limited availability but priced at approximately $200-$400/month for compounded or existing formulations.
Market Share:
Xenazine maintains approximately 60% of the Huntington’s chorea drug market, with teprotumazine and deutetrabenazine vying for the remainder.
Healthcare Coverage and Reimbursement
- Reimbursement policies favor branded Xenazine for specific indications due to existing coverage agreements.
- Cost-sharing varies by insurer, often leading to copay assistance programs.
Regulatory Considerations
- FDA approved in 2008; no recent label changes.
- Pending or recent approval of extended indications could influence market size and pricing.
- Risk management and REMS programs limit distribution channels, impacting market expansion.
Strategic Opportunities and Risks
Opportunities:
- Launch of biosimilars or generics could reduce prices.
- Extended indications in other movement disorders or neurodegenerative diseases could expand demand.
Risks:
- Patent challenges or expiry leading to price erosion (expected late 2024-2025).
- Entry of cheaper alternatives or generics reducing revenue.
- Regulatory changes affecting reimbursement and approval pathways.
