Which manufacturers make quetiapine 300 mg tablets?
The specific manufacturer(s) for “quetiapine 300 mg” depend on the exact product form (immediate-release vs extended-release) and the brand/generic name on the label. Many countries carry multiple equivalent strengths and dosage forms, often with different marketing authorization holders and manufacturers.
To identify the current rising supplier/manufacturer for the 300 mg dose, you typically need the exact product identifier (brand name and whether it is XR/ER or IR) and the market/country.
How do I find the exact quetiapine 300 mg manufacturer for my country?
Search using:
- The full name on the package (including “XR/ER” if present)
- The strength “300 mg”
- The country or pharmacy you’re using
- The “manufacturer” and “marketing authorization holder” fields on the box or leaflet
If you share the brand name (and whether it’s XR/ER or IR) plus your country, I can narrow it down to the likely manufacturer(s) for that exact presentation.
Is 300 mg quetiapine usually XR/ER or IR? Why that matters for manufacturers
Quetiapine 300 mg is commonly sold as extended-release (XR/ER) in many markets, but immediate-release (IR) products also exist. Manufacturers can differ by formulation and release type even when the strength is the same, so checking whether the product is XR/ER or IR is often the fastest way to get the correct manufacturer.
Patent/exclusivity and why it affects “who makes” the 300 mg dose
When a brand or long-running generic supply changes, it’s often driven by patent expiry, exclusivity, or new generic approvals.
