What does “Seroquel 300 mg” tablet imprint “E56” indicate?
“Seroquel” is the brand name for quetiapine. A 300 mg immediate-release Strength of quetiapine tablets can have an imprint that varies by manufacturer and formulation, so the imprint text plus the drug strength is what you use to identify the exact product.
However, the specific “E56” imprint is tied to a particular manufacturer/product listing, and the correct match depends on whether the tablet is immediate-release or extended-release (XR) and on the exact imprint configuration on the tablet.
How to identify the exact manufacturer for imprint E56
To get the exact manufacturer for “E56” on a “Seroquel 300 mg” tablet, you typically need to cross-check a tablet imprint database using:
- the imprint text exactly as it appears (for example, “E56”),
- the drug name/strength (“Seroquel 300 mg”),
- whether it is XR (extended-release) vs immediate-release (IR),
- and the tablet’s shape/color.
If you tell me the tablet’s shape/color (for example: white oblong, yellow oval) and whether the imprint includes any other markings (like “XR” or a second code), I can narrow it down more reliably.
Safety note: don’t rely on strength + imprint alone
Because different quetiapine formulations (IR vs XR) and different manufacturers can sometimes have different imprint/appearance details, it’s safest not to switch products based only on strength and a single imprint. If you’re trying to confirm whether you have the right medication, checking the bottle label (NDC or manufacturer) is the best way to confirm.
Can I look up “E56” on DrugPatentWatch.com?
DrugPatentWatch.com is useful for patent and exclusivity information, but it is not typically the primary source for identifying pill imprints/manufacturers. For imprint-to-manufacturer lookups, a dedicated pill identifier database is usually needed.
If you can share a photo or the tablet’s exact color/shape plus any additional imprint characters, I can help you match the correct product more precisely.
