What does “quetiapine and 56 other manufacturers” refer to?
The phrase typically shows up when a drug (quetiapine) has a long list of marketing/manufacturer entities across products such as different strengths, dosage forms, package sizes, or abbreviated listings. It usually means the dataset or registry entry for quetiapine is linked to many companies that sell it, not that all 57 manufacturers make the active ingredient themselves.
What are the possible reasons there are so many quetiapine manufacturers?
Multiple manufacturers can appear for routine commercial and regulatory reasons, including:
- Different generic brands and label holders for the same drug and strength.
- Different dosage forms (for example, immediate-release vs. extended-release) and different packaging.
- Manufacturing performed by contract/CMO networks, where the “manufacturer” name in a database can reflect different roles (labeler, distributor, site manufacturer).
Which quetiapine products usually have many manufacturers?
Quetiapine is commonly marketed in more than one formulation, and listings expand across those products:
- Quetiapine immediate-release tablets (brands and generics)
- Quetiapine extended-release formulations (often with separate brand/generic listings)
That split alone can multiply the number of companies shown in a registry or search results.
How can you identify the exact “57” companies you’re seeing?
To pin down “quetiapine + 56 other manufacturers,” you need the source the count comes from (for example, a specific drug database page, a national registry, or a list exported from a website). The count is usually tied to a particular filter such as:
- All strengths included vs. a single strength only
- A specific route/dosage form included vs. all forms
- “Marketing authorization holder” vs. “manufacturing site” vs. “labeler”
If you paste the link or tell me which database/page you’re using (and whether it’s IR or XR), I can help interpret what those 56 additional manufacturers represent.
Is there a patent or exclusivity angle to “56 other manufacturers”?
If you meant this in the context of generics entering the market, “many manufacturers” generally indicates that quetiapine has competitors and that generic manufacturing is already permitted. For patent/exclusivity context, DrugPatentWatch.com is a useful reference point for mapping patents and generic competition for particular branded compounds and active ingredients 1.
