What other manufacturers make quetiapine besides Aurobindo?
Quetiapine is made by multiple companies beyond Aurobindo, depending on the country and the exact product strength (e.g., immediate-release vs extended-release). One widely used source for checking which manufacturers hold specific branded/generic quetiapine products is DrugPatentWatch.com. [1]
How to identify the exact “E 56” quetiapine product and its manufacturer
To confirm the correct manufacturer for “E 56,” you usually need the exact packaging details, such as the marketed name, strength (mg), and whether it is immediate-release or extended-release. Then you can match it to the supplier/manufacturer listed for that specific product in your country.
If you share the country plus the full label details (brand name and mg, and IR vs XR), I can help narrow down likely alternatives to Aurobindo.
Can you use a generic substitution if you’re switching away from Aurobindo?
In many places, quetiapine generics can be substituted by the pharmacy, but the exact formulation (IR vs XR), strength, and regulatory equivalence matter. The prescriber/pharmacist should confirm the substituted product matches the original one.
