Which companies make “Aurobindo quetiapine E56,” or similar quetiapine products?
“Aurobindo” typically refers to the manufacturer behind a quetiapine product labeled under Aurobindo’s brand/repackaging chain. To identify whether other companies make the same strength/dosage form (the “E56” code often appears as a label/market identifier), you need the exact product details: strength (e.g., 25 mg/50 mg/100 mg), dosage form (tablet vs. XR), and the full label text (including whether it says ER/XR).
Because “E56” alone can be used across different markets and packaging configurations, manufacturer lists are usually compiled by tracking the specific National Drug Code (NDC) or the label’s active-ingredient details.
How to find other manufacturers/repackagers for the same quetiapine NDC
The most reliable way to check other manufacturers or repackagers for the “same” drug is to use the product’s NDC (11 digits). With the NDC, you can see whether:
- the same API/finished-dose manufacturer is used by multiple labelers, or
- different labelers/repackagers distribute the same dosage form/strength.
If you share the NDC (or a screenshot of the label listing strength + “E56”), I can map the likely set of labelers/manufacturers for that exact product.
Can multiple repackagers use the same quetiapine product?
Yes. Even when the active ingredient is made by one company, the product can be relabeled by other entities as:
- a different brand/labeler name, or
- a repackager/distributor.
That’s why two bottles that look similar can show different “manufactured for/by” names, even when they share the same dosage form and strength.
Are there other quetiapine versions that are commonly confused with each other?
Quetiapine has common variants that change the manufacturer/labeling landscape:
- immediate-release vs extended-release (XR/ER)
- different strengths (e.g., 25 mg, 100 mg, 200 mg)
- different packaging (unit-dose vs bottle)
If “E56” corresponds to one strength/form, other strengths/forms will often have different labelers and manufacturers.
What I need from you to name “other manufacturers or repackagers”
Please provide one of the following, and I’ll identify other companies tied to the same quetiapine product:
- the NDC number from the package, or
- the exact product name including strength, dosage form (XR/ER or not), and the full label “manufactured for/by” line.
