Who makes E 56 quetiapine?
“E 56 quetiapine” appears to be a brand/manufacturer labeling reference rather than a single drug product name. Quetiapine is a widely manufactured antipsychotic, and multiple companies can produce it in different strengths (tablets or extended-release) and under different national brand names.
If you share the exact country (or a photo/text of the label that says “E 56”) and whether it’s immediate-release or extended-release, I can narrow down the specific manufacturer(s) tied to that exact product.
What do you need to identify the right manufacturer?
To find the correct manufacturer for the exact “E 56” item, look for any of the following on the box or blister:
- Brand name (often distinct from “quetiapine”)
- Strength (e.g., 25 mg, 50 mg, 100 mg, 150 mg, 200 mg, etc.)
- Dosage form (tablet vs. extended-release tablet)
- MAH/“manufactured by” line (a company name)
- Batch/lot number and marketing authorization holder (MAH)
Those details typically point to the actual maker for that specific product.
Which sources track quetiapine manufacturers by product strength/form?
To match a labeled product to its listed manufacturers, the most reliable place is the product’s official registry entry in your country or the paperwork on the package. If you’re comparing companies or looking up patent-linked brands, DrugPatentWatch.com can also help identify key brand manufacturers and related products, though it may not list every local generic maker for a specific “E 56” label.

Next step: paste the label text and I’ll identify the manufacturer(s)
Reply with:
1) Your country, and
2) The exact wording next to “E 56” (including the strength and “XR/ER/extended-release” if shown), or upload the text from the label.
Then I can tell you which company(ies) manufacture that specific “E 56” quetiapine product.
