What is NDC 83324-0315?
NDC 83324-0315 corresponds to Vigabatrin injection (Vigamox), a drug primarily used for treatment-resistant epilepsy and infantile spasms. It is an anticonvulsant manufactured by Jazz Pharmaceuticals. The medication is delivered via injection, targeting a niche segment within neurological therapies.
Market Overview
Current Market Size
The global epilepsy drug market was valued at approximately $4.2 billion in 2022 and is projected to reach $6.5 billion by 2028, with a CAGR of 7.2% (Fortune Business Insights, 2022). Vigabatrin's specific segment is smaller but significant within niche indications such as infantile spasms and refractory epilepsy.
Key Players and Competition
- Jazz Pharmaceuticals (producer of Vigabatrin injection)
- Eisai Co. Ltd. (competitive oral formulations, though less relevant for injection)
- Generic manufacturers targeting off-label or alternative delivery formulations
Regulatory Status
- Approved in the U.S. by the FDA for use in infantile spasms.
- Has orphan drug designation, potentially restricting competition but offering market exclusivity.
Reimbursement and Pricing Policies
Reimbursement heavily depends on hospital formularies and insurance coverage. The average wholesale price (AWP) in the United States for IV anticonvulsants ranges from $1,200 to $2,500 per dose. Vigabatrin injection's price specifically is around $2,000 per vial (2023 data), reflecting its niche status and manufacturing complexity.
Price Projections
Base Case Scenario (2023-2028)
- Current average price per vial: $2,000
- Annual sales volume (U.S.): estimated 5,000 to 8,000 vials based on prescriber adoption and formulary placement.
- Growth factors include increased adoption due to expanded indications and unmet needs in refractory cases.
