What is NDC 46122-0141?
The drug with National Drug Code (NDC) 46122-0141 is a specific formulation marketed under a designated label. The NDC identifies dosage, formulation, and packaging. Based on current publicly available data, this NDC corresponds to Lisdexamfetamine dimesylate in a specific packaging size, commonly prescribed for ADHD.
Market Overview
Indications and Usage
Lisdexamfetamine dimesylate (brand: Vyvanse) is approved for:
- Attention deficit hyperactivity disorder (ADHD) in children aged 6 and older, and adults.
- Moderate to severe binge eating disorder in adults.
Market Size and Adoption
The ADHD market in the U.S. exceeds $12 billion annually, with stimulant medications like Vyvanse contributing significantly. The prescriptions for Vyvanse constitute approximately 20% of stimulant prescriptions, roughly 1.5 million annually.
Key Competitors
- Adderall (amphetamine salts)
- Concerta (methylphenidate)
- Dexedrine (dextroamphetamine)
Vyvanse's market share is bolstered by its once-daily dosing and abuse-deterrent profile. As of 2022, Vyvanse maintained around a 12% share of the overall ADHD medication market.
Regulatory and Patent Environment
- Patent protections for Vyvanse extend until at least 2024.
- Pending biosimilar or generic entries could erode market share thereafter.
- FDA exclusivity lapses for key formulations scheduled for 2024-2025.
Price Trends and Projections
Current Pricing Data
- Wholesale Acquisition Cost (WAC) for a 30mg capsule: approximately $250 per month (per payer data).
- Average out-of-pocket costs for patients: $30–$60/month, depending on insurance coverage.
- Generic versions are not yet broadly available; pricing remains stable.
Historical Price Trends
From 2018 to 2022, wholesale prices for Vyvanse increased at an average annual rate of 3%. The lack of generics delayed significant price erosion.

FAQs
1. When will generic versions of NDC 46122-0141 become available?
Patent protections extend until at least 2024; generics are expected to penetrate the market shortly thereafter, with widespread availability by 2025.
2. How is insurance coverage likely to affect pricing?
Insurance coverage typically lessens out-of-pocket costs for patients, but formulary restrictions and copay policies influence net prices received by manufacturers.
3. What impact will biosimilars have on the market?
Although biosimilars are not directly related to small molecules like Vyvanse, biosimilar competition in related areas can influence overall stimulant market dynamics.
4. Are there alternative treatments that could replace Vyvanse?
Yes. Non-stimulant medications (e.g., atomoxetine), other stimulants (e.g., Adderall), and behavioral therapies can serve as alternatives, affecting demand.
5. How does the current patent landscape influence market entry?
Patent protections delay generic entry, maintaining higher prices. Patent expiry lined up for 2024-2025 opens opportunities for generics, increasing price competition.
