Nexium (esomeprazole) and Protonix (pantoprazole) are both Proton Pump Inhibitors (PPI) that are approved by the Food and Drug Administration (FDA) for the treatment of erosive espophagitis, gastroespohgael refulx disease (GERD), Helicobacter pylori infection and Zollinger-Ellison syndrome. PPIs work by inhibiting the action of the proton pump which supresses stomach acid.
Additional Indications for Protonix
Protonix is also approved for the treatment of duodenal ulcers, gastric ulcers, peptic ulcers and ulcer prevention.
Additional Indications for Nexium
Nexium is approved for pathological hypersecretory conditions, and NSAID-Induced Gastric Ulcers in addition to the conditions mentioned above.
Duration of Therapy
Perhaps the biggest difference between these two PPIs is the recommended duration of treatment. Nexium is only indicated for short term therapy, although physicians can prescribe it for longer. Protonix is typically prescribed for longer treatment. Nexium also needs to be taken one hour prior to eating. Protonix may be taken at any time.
