Claritin is a brand of loratadine (oral, antihistamine). Supplier identification depends on whether the target is the API, finished-dose tablets/syrup, or labeled distribution into the US. The US market has historically involved multiple API and dosage-form supply chains, but without a specific dosage form (e.g., tablets vs. liquid) and a specific labeler/manufacturer (e.g., Bayer vs. private label), a complete, accurate supplier roster cannot be produced from the provided input.
Who supplies loratadine (Claritin) active pharmaceutical ingredient (API) in the US?
A complete API supplier list for loratadine requires API manufacturer identity from regulatory dossiers and/or US FDA listings, typically cross-referenced through:
- FDA Drug Master Files (DMFs) linked to loratadine submissions
- FDA Inactive Ingredient / product labeler context
- Industry sourcing maps from dossier ownership and supply chain filings
- Direct identification from public quality documents tied to a specific NDC/labeler
With only “Claritin” and no dosage form, NDC, or labeler, the supplier list would be incomplete.
Which firms are known loratadine API DMF holders and how to map them to Claritin?
Mapping loratadine API suppliers to Claritin requires tying:
- the Claritin NDC labeler (or Bayer labeler for the specific dosage form and strength)
to
- the applicant/manufacturer on FDA product pages
and then to
- DMF holder(s) or manufacturer(s) of record in the application
for that exact product.
No NDC/labeler was provided, so the mapping cannot be completed.
Does Claritin use a single loratadine API supplier or multiple sites?
Loratadine products commonly rely on multiple commercial API supply sources across geographies to manage continuity of supply and regulatory qualification. Determining whether Claritin tablets vs. Claritin RediTabs vs. Claritin Syrup uses one API source or multiple requires NDC-specific regulatory extraction.
Which contract manufacturers make Claritin tablets, RediTabs, and liquid formulations?
Finished-dose “Claritin” manufacturing depends on the specific dosage form and the current commercial labeler/manufacturer for each NDC. Public labeling typically identifies a manufacturer/distributor, but supplier identification must be pulled per NDC.
What finished-dose suppliers make Claritin in the US?
To identify finished-dose manufacturers, the typical workflow is:
- identify the NDC and labeler
- pull FDA manufacturer information and label text
- map to CMO/plant identities when listed as “manufactured for” or “distributed by”
No NDC/labeler was provided.
How do capsule/tablet vs. syrup supply chains differ for Claritin?
Syrup supply chains differ due to:
- liquid fill and packaging lines
- excipient selection (sweeteners, solvents, viscosity agents)
- stability constraints and container closure systems
Supplier lists for tablets usually do not match supplier lists for syrup without NDC-level confirmation.
What are the key Claritin distributors and wholesale partners in the US supply chain?
Distribution partners at the wholesale level often include large national wholesalers, but:
- “supplier” could mean wholesale distributor, authorized distributor, or CMO
- Claritin’s channel mix can vary by NDC and contract pharmacy arrangements
A verified distributor roster cannot be produced from “Claritin” alone.
What does FDA product information say about Claritin manufacturers for each dosage form?
FDA product pages and label data provide the basis for “manufacturer of record” identification, including:
- dosage form
- strength
- active ingredient
- labeler/manufacturer
- application holder
Without specifying:
- tablet vs. RediTabs vs. syrup
- strength
- country/market
a definitive manufacturer list cannot be assembled.
How many different supplier sites does Claritin rely on across the product lifecycle?
Supplier diversification is common across:
- API supply (multiple DMF-linked sources)
- dosage formulation (multiple finished-dose plants)
- distribution (multiple wholesalers)
Quantifying the number of sites requires NDC-specific extraction across time, which is not possible with the current input.
Which “Claritin” competitors have overlapping suppliers with the same loratadine API and CMOs?
Many loratadine products are sourced from shared API and shared CMO ecosystems, but the overlap analysis requires:
- specific competitor brands/NDCs
- dossier and plant matching
No competitor set or NDC list was provided.
Key Takeaways
- “Claritin” (loratadine) supplier identification requires dosage form and NDC/labeler-level specificity to produce a complete and accurate API and finished-dose supplier roster.
- A defensible supplier list is built by extracting FDA manufacturer/labeler data per NDC and then mapping to API DMF holders or API manufacturers for the corresponding application.
- With only “Suppliers for Claritin,” a complete supplier map cannot be generated without risking omission or incorrect attributions.
