Who makes omeprazole?

Omeprazole is made by many pharmaceutical companies around the world. The drug was originally developed by AstraZeneca (it’s sold under brand names like Losec in many markets and Prilosec in the U.S.), but today most markets dispense it as a generic made by numerous manufacturers.

Common generic makers include Teva, Sandoz, Mylan (now Viatris), Sun Pharma, Lupin, Dr. Reddy’s, Cipla, and many others.
