PROTONIX

INDICATIONS

Protonix blocks the production of stomach acid. It is prescribed to heal a condition called erosive esophagitis (a severe inflammation of the passage to the stomach) brought on by a persistent backflow of stomach acid (gastroesophageal reflux disease). Later, it may be prescribed to maintain healing and prevent a relapse. It is also used in the treatment of conditions marked by constant overproduction of stomach acid, such as Zollinger-Ellison syndrome. Protonix is a member of the “proton pump inhibitor” class of acid blockers.
