Question: what is the difference between nexium and salpraz?
Answer: To be fair, for GERD Nexium 40 mg (prescription) was slightly better than omeprazole 20 mg (OTC) at week eight. But omeprazole also comes in a 40 mg tablet; 20 mg is a lower dose omeprazole. There was no difference between Nexium 20 mg and omeprazole 20 mg at week four.
