Who makes “E56 Seroquel”?
“E56” isn’t a standard, internationally recognized code for a specific Seroquel product or manufacturer by itself. “Seroquel” is the brand name for quetiapine, and different countries use different internal codes and labeling systems, so the manufacturer depends on the exact product (strength, dosage form, and the country you’re looking in).
If you share any of the following, I can help identify the manufacturer more precisely:
- the full wording on the pack (especially the strength, like 25 mg/100 mg/200 mg, and whether it is immediate-release or extended-release)
- the country shown on the label
- the “E56” context (is it printed near the NDC/GTIN, batch/lot code, or packaging code?)
Is “E56” a batch/lot code rather than a manufacturer identifier?
In many cases, codes like “E56” on medicine packaging can be tied to logistics or internal manufacturing/packaging rather than naming the drug’s marketing/manufacturing company. Manufacturer details are more reliably found on the label under headings like “Manufacturer,” “Packaged by,” “Marketed by,” or by checking the NDC/GTIN and local regulatory listing for your country.
What name should you look for on the label?
For Seroquel (quetiapine), the manufacturer/marketer shown on your local product labeling is the best source for identification, since it can vary by market and whether the product is:
- immediate-release vs extended-release
- brand vs generic quetiapine
- original brand product vs a specific distributor/packager for that region
Can DrugPatentWatch help find the exact company tied to your quetiapine product?
DrugPatentWatch can be useful for mapping brand and generic quetiapine market authorization and related rights by product, but it still depends on knowing which exact product variant you mean (strength/form and country). If you can provide those details, I can point you to the most relevant DrugPatentWatch page: https://drugpatentwatch.com/
Fast next step
Reply with a photo or the exact text from the “E56” area plus the strength (e.g., “Seroquel XR 50 mg” or “Seroquel 100 mg”) and your country. Then I can tell you which company is listed as the manufacturer/packager for that specific Seroquel product.
