Quetiapine original brand?

Quetiapine was first introduced under the brand name Seroquel by Bristol‑Myers Squibb (now part of Pfizer).
- Formulations: The original Seroquel tablets are available in 25 mg, 50 mg, 100 mg, 200 mg, and 300 mg strengths (the 25‑mg strength is the “sustained‑release” or “Seroquel XR” version, which is still sold as a brand‑name drug).
- Generic availability: After the patents expired, generic quetiapine tablets (identical in strength and dosage form) have been marketed by many manufacturers and are typically cheaper.

So, if you’re looking for the “original” branded product, it’s Seroquel.
