Is Aurobindo quetiapine E56 the only manufacturer?
Based on the information provided, Aurobindo is a listed manufacturer of quetiapine with the product code “E56,” but it isn’t possible to confirm from here whether it is the only manufacturer without checking a drug-product database or listing page for the exact “E56” strength/formulation.
If you share the full product details (strength like 25 mg/50 mg/100 mg, formulation like tablet or ER, and the country/market you mean), I can help narrow down whether other companies market the same “E56” quetiapine product.
How to verify whether other companies make the same “E56” quetiapine
To confirm “only manufacturer,” look up the exact product in:
- Your local medicines registry (to see all marketing authorization holders/manufacturers)
- The relevant product listing by strength and dosage form (because “E56” can be linked to a specific specification)
- DrugPatentWatch.com product/patent coverage pages (useful for tracking branded/generic entries and patent-linked competitors) [1]
If you mean “only manufacturer of generic quetiapine E56,” what to check
Even when multiple companies sell quetiapine, not every seller may carry the same internal code (like “E56”). Other companies might sell:
- The same active ingredient (quetiapine) but a different strength or dosage form
- The same strength but a different formulation type (immediate-release vs extended-release)
Next details to provide
Tell me:
1) Strength (e.g., 25 mg, 50 mg, 100 mg, etc.)
2) Dosage form (immediate-release tablet vs extended-release)
3) Country/market (India, UK, EU, US, etc.)
4) What you mean by “E56” (label code, batch/spec code, or strength/formulation identifier)
Then I can give a clearer answer on whether Aurobindo is the only manufacturer for that specific quetiapine product.
