Matrix claims that Pantoprazole Sodium DR tablets, a proton pump inhibitor drug, are generic version of Wyeth‘s Protonix DR tablets.
Protonix is in a group of drugs called proton pump inhibitors which decrease the amount of acid produced in the stomach.
Protonix is used to treat erosive esophagitis (damage to the esophagus from stomach acid) and other conditions involving excess stomach acid such as Zollinger-Ellison syndrome.
