what is the difference between pantoprazole sodium and omeprazole?
Protonix (pantoprazole) is usually only taken once a day for long-lasting heartburn relief, but it can increase your risk of bone fractures if you've used it for a long time. Prilosec (omeprazole) lasts longer (up to 72 hours) than other classes of acid reducers (like Zantac, Pepcid, or Tums).
