are all ppi drugs the same?
Proton-pump inhibitors (PPIs) like esomeprazole (Nexium), pantoprazole (Protonix), omeprazole (Prilosec) and lansoprazole (Prevacid) are commonly used to treat acid reflux (GERD), acid regurgitation and heartburn. They all work the same way and prevent parietal cells in the stomach lining from secreting acid.
