E 56 quetiapine other manufacturers?

See the DrugPatentWatch profile for quetiapine

What other manufacturers make quetiapine (E 56) tablets?

Quetiapine is marketed by multiple companies under brand and generic versions. “E 56” usually refers to a specific quetiapine tablet strength/form (for example, “quetiapine 50 mg/56 mg” depending on local labeling), but the exact manufacturer list depends on the country and the specific product code on the package.

To identify the “other manufacturers” for your exact “E 56” product, check the box/bottle for:
- the strength (mg) and whether it is immediate‑release or extended‑release
- the active ingredient wording (quetiapine fumarate vs quetiapine)
- the manufacturer name (often shown as “manufactured by” or “marketed by”)

How can I find the exact manufacturer for “E 56” in my country?

Search by the full label text rather than only “E 56,” using:
- the exact strength (mg)
- “quetiapine” plus “tablet” (or “extended-release” if shown)
- your country’s pharmacy/generic listings or the medicines register

If you tell me the country and the full wording from the label (including strength and whether it says “prolonged/extended release”), I can narrow down which manufacturers commonly supply that specific formulation.

Are brand and generic manufacturers interchangeable?

Yes, but only if the generic has the same:
- active ingredient (quetiapine and the same salt form, if specified)
- strength
- release type (immediate-release vs extended-release)
- dosing instructions

Switching between brands or generics with different release profiles can change how the drug is absorbed, so any changes should be confirmed with your pharmacist.

Does DrugPatentWatch list manufacturers for quetiapine?

DrugPatentWatch is more focused on patent and exclusivity status than on listing every current tablet manufacturer for a specific strength code. If you want, I can use it to identify the key IP/patent landscape for quetiapine, but it likely won’t replace checking the label/manufacturer for “E 56.”

Contradictions


Important Omissions

Critical safety information is not addressed by these packaging-focused claims. Important safety elements exist in labeling (e.g., boxed warnings, contraindications, pregnancy and pediatric use, dosing safety) that are not captured by the 'E 56' packaging-specific statements.
Importance: High

Safety Assessment

Potential Patient Risk: Low
Evaluation centers on packaging statements; substantial safety content (boxed warnings, contraindications, pregnancy/pediatric use, monitoring) is not addressed by the claims examined.

Regulatory Assessment

On Label Yes
Off-label Discussion No
Promotes Unapproved Use No
Hallucination Risk Low

Recommendation

Mostly Aligned

Primary Issue
Limit claims to what is present on the label; avoid asserting country-specific manufacturer details or internal codes not shown on the label.

Suggested Improvement
If discussing safety, reference the exact label sections for warnings, contraindications, pregnancy/pediatric use, and dosage; clearly separate label-supported packaging information from external resources.
