ZOMIG (zolmitriptan) is distributed in the US by AstraZeneca Pharmaceuticals LP under the prescription brand. Manufacturing and supply are handled through a network that includes AstraZeneca’s internal sites and contract manufacturing partners used for finished dose production and packaging. Zolmitriptan supply chains also involve API and intermediate sourcing that feed multiple finished-dose makers globally, depending on strength, dosage form, and market.
Who supplies ZOMIG (zolmitriptan) in the US?
US brand distribution: AstraZeneca Pharmaceuticals LP is the labeled holder/distributor for ZOMIG products listed in US FDA systems (Orange Book and labeling).
Common supplier categories
- Finished dose manufacturers (FDF): produce ZOMIG tablets and ZOMIG Nasal Spray (and, where applicable, other ZOMIG presentations) for AstraZeneca branding.
- Packaging and labeling partners: bottle blister packs, carton, and insert packaging under GMP.
- API and intermediate suppliers: produce zolmitriptan API and/or key intermediates that are then finished into tablet or spray formulations.
- Logistics and distribution: wholesalers and 3PLs move product through the US distribution chain after release testing.
What companies manufacture ZOMIG tablets and zolmitriptan nasal spray?
A complete, product-by-product mapping of which specific plants or contract manufacturers make each ZOMIG dosage form requires a dossier-level look at current FDA labeling manufacturing sections and current Orange Book “Applicant/Manufacturer” entries for each NDA listing. That plant-level mapping is not fully determined from the information provided here.
What can be stated from the US regulatory perspective: ZOMIG products are marketed under AstraZeneca’s label, and manufacturing is performed under GMP by AstraZeneca and its supply chain partners, with site attribution varying by dosage strength and lifecycle stage (launch-era vs. post-sourcing changes).
ZOMIG dosage forms and typical supplier roles
- Tablets (including multiple strengths):
- Tablet manufacturing, granulation and compression
- Film coating
- Packaging into bottles or blisters
- Nasal spray:
- Aqueous formulation filling into nasal device components
- Device assembly and inspection
- Packaging into cartons with patient instructions
Where does ZOMIG zolmitriptan API come from?
Zolmitriptan API is sourced from specialty chemical manufacturers that produce chiral or routed intermediates and finish to API grade under cGMP. In practice, API sourcing can shift over time by market authorization, quality agreement terms, and supply risk management.
From a competitive-intelligence standpoint, ZOMIG API and intermediates typically originate from one or more of:
- Chiral API producers with route capability to zolmitriptan
- Custom synthesis and API manufacturers with US- and EU-facing quality systems
However, a definitive list of exact API suppliers for ZOMIG cannot be produced from the information provided in this request.
What does the Orange Book say about ZOMIG suppliers and listings?
The FDA’s Orange Book identifies:
- Active ingredient (zolmitriptan)
- Dosage form(s)
- NDA / applicant
- Patents and exclusivities tied to those products
Orange Book entries also include “applicant” and sometimes manufacturing labeling information, but patent/exclusivity listings are not a direct substitute for a full supplier map.
For business use: Orange Book confirms the regulatory label holder and provides a reference point for which legal entities are responsible for the NDA. For plant-level sourcing, the prescribing information and CMC sections are the primary artifacts.
How can you identify ZOMIG manufacturers from product labeling?
The most reliable supplier identification method is the “Manufactured for” or “Distributed by” sections in ZOMIG labeling for each dosage form and strength. Labeling often lists:
- Applicant/distributor entity
- Manufacturer entity
- Address of the manufacturer site (or “manufactured by” contract maker)
For supply chain due diligence and dispute work, label-based manufacturer identification is higher fidelity than generic web claims.
Which companies are potential competitors in zolmitriptan supply (generics and authorized partners)?
Even though ZOMIG is brand-distributed by AstraZeneca, competitor entry in zolmitriptan often includes:
- Generic manufacturers filing ANDAs for tablets and nasal spray equivalents
- Authorized generic or supply-license programs depending on market dynamics
Which companies are active depends on whether a specific zolmitriptan dosage form has an active generic in the market at present. This cannot be fully enumerated from the supplied prompt alone.
What is the sourcing risk profile for ZOMIG supply?
Typical risks in triptan supply chains include:
- API single-source or limited-source constraints for a niche molecule
- Chiral synthesis capacity bottlenecks
- Device component availability for nasal spray presentations
- Regulatory change control and site transfer timing
ZOMIG’s supply continuity is managed through commercial sourcing redundancy (multiple lots and, commonly, multiple manufacturing sites for a given dosage form), but exact site redundancy must be validated against current labeling and FDA CMC submissions.
What suppliers are used for ZOMIG manufacturing in other regions (EU/UK)
Across major markets, Zomig supply networks often mirror:
- Multi-site EU production for tablets
- Separate spray manufacturing and device assembly partners
- API sourcing from chemical manufacturing clusters
A region-specific supplier list requires market-specific labeling and local regulatory submissions, which are not provided here.
Key Takeaways
- US distribution/labeling for ZOMIG is under AstraZeneca Pharmaceuticals LP.
- ZOMIG supply chain includes finished dose manufacturers, packaging/labeling partners, and API producers, with supplier assignments varying by dosage form, strength, and lifecycle.
- A precise supplier list by company and facility requires extraction from current ZOMIG labeling manufacturing statements and/or NDA/applicant manufacturing references; the prompt does not include those artifacts.
FAQs
1) Who is the distributor for ZOMIG in the United States?
AstraZeneca Pharmaceuticals LP.
2) Are ZOMIG nasal spray suppliers different from tablet suppliers?
Typically yes. Nasal spray has device assembly and filling steps that are often handled by different manufacturing capability sets than tablet production.
3) How do I find the exact manufacturer of ZOMIG for a specific strength?
Use the “Manufactured for” / “Manufactured by” statements in the prescribing information for that exact dosage form and strength.
4) Where can I check ZOMIG legal entity responsibility and listings?
The FDA Orange Book provides NDA/appliant-level listing context, while the label provides manufacturing-entity context.
5) Do generic zolmitriptan suppliers compete with AstraZeneca’s ZOMIG manufacturing?
They compete at the product level in the market, but supply chain overlap depends on whether API or intermediates are shared and whether contract production is used across brands.
