What is the difference between zantac and protonix? ?
They are different drugs that are used for some of the same purposes. Zantac is used to treat GERD or ulcers. They both work to reduce the amount of acid in your stomach. Protonix has been proven to help heal the damage to the esophogus (throat) that may have occured due to the acid from the stomach entering the throat. I think Zantac takes longer to work than Protonix.
