Esomeprazole magnesium is the generic name for the drug.. my father has idiopathic pancreatitis(diet) and was prescribed nexium. Nexium works better but the 1st generation and now generic omeprazole/ranitidine serve the same function but require more frequency. For example in a hospital pantoprazole and similar ppi are used instead for cost effectiveness..
Tried and true so much cheaper. Id like to meet someone who could home brew nexium I'd hug them.
