Question: what is the difference of omeprazole and esomeprazole?
Answer: Compared to omeprazole 20 mg, esomeprazole 40 mg provides greater acid control in patients with GERD and keeps stomach pH at higher than 4 for a longer period of time (higher pH = less acidity = less pain). What about esomeprazole 40 mg vs. omeprazole 40 mg?
