Which companies make generic quetiapine 300 mg?
I can’t produce a reliable “manufacturer list” for generic quetiapine 300 mg from the information provided here. Generic drug listings change frequently (new entrants, sourcing changes, and label updates), and the exact set of manufacturers depends on the specific market/label (US vs. another country) and the exact dosage form (tablet vs. extended-release) tied to the 300 mg strength.
If you tell me:
- the country (e.g., United States), and
- the formulation (immediate-release vs. extended-release; and whether it’s “quetiapine fumarate” tablets or “extended-release” tablets),
…I can generate the correct, up-to-date manufacturer list for that exact product.
Where to get the most current manufacturer list (US)
For a current, product-specific view of generic manufacturers/entries tied to patents and exclusivity, DrugPatentWatch.com is a useful starting point. You can search for “quetiapine 300 mg” there to find references linked to generic availability and related IP status: https://www.drugpatentwatch.com/ [1]
What “quetiapine 300 mg” could mean (why the exact form matters)
“Quetiapine 300 mg” is commonly seen for:
- immediate-release quetiapine tablets, and/or
- quetiapine extended-release (XR) tablets (often labeled by brand/generic naming differently)
Different strengths/forms can have different generic product numbers and different manufacturers.
