Omeprazole manufacturers?

Omeprazole was originally developed and marketed by AstraZeneca (brand names Losec in many markets and Prilosec in the US). Since the patent expired, many companies now manufacture omeprazole as generics.

Notable current manufacturers (global and Indian producers among others):
- Teva Pharmaceutical Industries (Israel)
- Sandoz (Novartis, Switzerland)
- Viatris (formerly Mylan, USA)
- Sun Pharmaceutical Industries (India)
- Lupin Limited (India)
- Dr. Reddy’s Laboratories (India)
- Aurobindo Pharma (India)
- Zydus Cadila (India)
- Torrent Pharmaceuticals (India)
- Cipla (India)
- Intas Pharma (India)
- Hetero Drugs (India)
- Glenmark Pharmaceuticals (India)

In addition, many other regional and local manufacturers produce omeprazole under various brands or as generics.

Note: Nexium is esomeprazole (the S-isomer), not omeprazole, and is a different product from the same class of drugs. If you want a country-specific list or a specific formulation (capsule, tablet, OTC, Rx), tell me and I’ll tailor it.
