AMBIEN CR Suppliers: Who Manufactures and Supplies the Ambien CR (zolpidem tartrate extended-release) Brand Drug
Ambien CR (zolpidem tartrate extended-release) is supplied in the US market through Allergan/AbbVie’s brand organization (current ownership) with commercial supply tied to licensed manufacturing sites used for FDA-labeled product. The competitive supplier map is driven by (i) the brand’s manufacturing and packaging network supporting the NDA product and (ii) generic entrants using ANDA supply chains and permitted labeling.
Who are the commercial suppliers of Ambien CR (zolpidem ER) in the US?
The brand supply chain for Ambien CR is aligned with AbbVie’s commercial operations for the zolpidem ER franchise in the US. In practical supplier terms, the “supplier” most relevant to buyers, pharmacies, and distributors is the labeled commercial manufacturer and packager stated on the FDA label, which reflects the parties responsible for release into US commerce.
What company supplies Ambien CR under the FDA label?
Label-holder/sponsor (brand organization): Allergan (now part of AbbVie).
Commercial supply channel: AbbVie distributor/wholesaler network for branded zolpidem ER product.
Which manufacturing sites typically produce the branded extended-release tablets?
Ambien CR is an oral extended-release dosage form. The manufacturing and packaging responsibilities for FDA-labeled product typically sit with one or more contract manufacturing organizations (CMOs) or internal AbbVie/Allergan manufacturing sites named on the FDA label and/or in NDA records.
What manufacturing companies produce Ambien CR tablets and where are they made?
Ambien CR is a solid oral extended-release product. Supplier identity in regulated drug supply is best evidenced by the FDA label “Manufactured for…” / “Distributed by…” text and the NDA labeling and drug product manufacturing information tied to the approved product.
How to identify the true AMBIEN CR product manufacturers
- Use the US package labeling for “Manufactured for” and “Distributed by” lines.
- Cross-check FDA’s drug label version for the current label changes.
- Use Orange Book/NDA product references to confirm dosage form, strength, and labeling.
Which companies supply generic zolpidem ER that compete with Ambien CR?
Generic competition for zolpidem extended-release is commonly handled by multiple ANDA holders with different supplier networks. Each ANDA’s commercial “supplier” is the labeled manufacturer/packager for that ANDA product, and the actual manufacturing may be executed by CMOs.
What supplier pattern do generic zolpidem ER products follow?
- ANDA holders (brandless) contract with at least one tablet manufacturing and compression network.
- Extended-release tablets require controlled formulation and release profiling, so ANDA suppliers typically use validated extended-release bead/granule or matrix manufacturing systems depending on the approved product.
What patent and exclusivity status affects Ambien CR’s supplier landscape?
Supplier diversity increases once exclusivity and key market-entry barriers lapse. For zolpidem ER products, the driver is not only patent expiration but also the availability of ANDA approvals and any relevant litigation/settlement that blocks launch.
When does Ambien CR lose exclusivity?
Ambien CR’s market exclusivity and patent coverage are product-specific and depend on the NDA and any listed patents in the FDA Orange Book for zolpidem ER. Once key patents expire and barriers clear, generic suppliers expand quickly.
What do FDA approvals say about Ambien CR’s labeled manufacturing and packaging?
FDA approval binds the product’s identity, manufacturing controls, and labeling. For “suppliers,” the regulatory anchor is the FDA label and NDA product description.
Regulatory evidence that governs who can supply Ambien CR
- NDA label manufacturer/packager statements (release responsibility)
- ANDA product labeling for authorized generic suppliers
- cGMP manufacturing site approvals in FDA databases linked to the NDA/ANDA
Which distributors supply Ambien CR to pharmacies and wholesalers?
In US practice, branded products flow through the major pharmaceutical distribution channels. The distributor and wholesaler-facing “supplier” is the product’s authorized distribution chain controlled by the brand organization, with distribution handled by wholesalers and specialty channels.
How does Ambien CR compare with other zolpidem ER competitors on supply?
Ambien CR’s supply differs from other zolpidem ER products mainly by:
- brand labeling vs generic labeling
- manufacturing network (brand vs ANDA labeled manufacturer)
- potential differences in excipients and extended-release technology, even when API is the same
Key Takeaways
- Ambien CR (zolpidem tartrate extended-release) is supplied through AbbVie’s brand organization (formerly Allergan) under the labeled product distribution chain.
- The most reliable way to identify exact tablet manufacturers and packagers is the current FDA label “Manufactured for…” and “Distributed by…” lines for Ambien CR.
- Generic zolpidem ER supply is fragmented across multiple ANDA holders, each with its own labeled manufacturing/packaging responsibility and CMO network.
- Patent/exclusivity clearance determines when additional suppliers enter and when launch barriers fall.
FAQs
1) Who is the “manufacturer” listed on the Ambien CR package label?
The manufacturer is the party named on the current US package labeling under “Manufactured for…” for Ambien CR.

4) Do CMOs supply Ambien CR extended-release tablets?
Extended-release tablet supply commonly uses qualified manufacturing and packaging networks, which may include CMOs, as reflected on the FDA label.
5) What drives the number of suppliers available for zolpidem ER?
ANDA approvals and any patent or settlement barriers that delay generic launch determine supplier count and timing.
