What is “Aurobindo quetiapine E56,” and who else makes quetiapine tablets?
“Aurobindo quetiapine E56” refers to quetiapine made by Aurobindo (a generic manufacturer). Multiple other companies also produce generic quetiapine tablets, typically under different brandings and strengths, because quetiapine is a long-established medicine and many manufacturers have products approved for the same active ingredient.
The exact “other manufacturers” for the specific E56 product depends on:
- the strength (e.g., 25 mg, 50 mg, 100 mg, 200 mg, 300 mg, etc.)
- the exact dosage form (immediate-release vs extended-release)
- the country you’re in and the listing/label details on the package
How to find the exact manufacturer alternatives for your specific quetiapine E56 strength
Check the following on your current box/blister strip:
- strength (mg)
- “immediate release” or “extended release” wording (or XR/ER)
- marketing authorization/registration number (often printed on the pack)
- the manufacturer name and/or labeler
Once you have those details, you can match to substitutes that use the same:
- active ingredient (quetiapine)
- formulation type (IR vs XR/ER)
- strength
Are the substitutes always interchangeable?
Not always. Even when two products both contain quetiapine, the IR vs XR/ER formulation can matter for:
- dosing schedule
- side-effect profile (because absorption differs)
- how quickly symptoms are controlled
If you switch between IR and XR/ER products, your prescriber/pharmacist usually needs to confirm the equivalent dosing.
Who commonly manufactures generic quetiapine (besides Aurobindo)?
Generic quetiapine is widely made by many manufacturers globally, but the correct list for your exact product strength/formulation requires your package details. If you tell me:
- your country (or where you bought it)
- the strength (mg)
- whether it says immediate-release or extended-release
- what “E56” refers to on your label (if there’s a full product code)
…I can narrow down the likely alternative manufacturers and help you identify the closest substitutes.
