Protonix, or Pantoprazole, is used to treat certain conditions in which there is too much acid in the stomach. It is used to treat duodenal and gastric ulcers and gastroesophageal reflux disease (GERD), a condition in which the acid in the stomach washes back up into the esophagus.
Protonix works by decreasing the amount of acid produced by the stomach

The active ingredient in PROTONIX (pantoprazole sodium) Delayed- Release Tablets is a substituted benzimidazole, sodium 5-( difluoromethoxy)- 2- [[( 3,4- dimethoxy- 2- pyridinyl) methyl] sulfinyl]- 1 H- benzimidazole sesquihydrate, a compound that inhibits gastric acid secretion. Its empirical formula is C16 H14 F2 N3 NaO4 S x 1.5 H2 O, with a molecular weight of 432.4. Pantoprazole sodium sesquihydrate is a white to off- white crystalline powder and is racemic. Pantoprazole has weakly basic and acidic properties. Pantoprazole sodium sesquihydrate is freely soluble in water, very slightly soluble in phosphate buffer at pH 7.4, and practically insoluble in n- hexane. PROTONIX is supplied as a delayed- release tablet for oral administration, available in 2 strengths. Each delayed- release tablet contains 45.1 mg or 22.6 mg of pantoprazole sodium sesquihydrate (equivalent to 40 mg or 20 mg pantoprazole, respectively) with the following inactive ingredients: calcium stearate, crospovidone, hydroxypropyl methylcellulose, iron oxide, mannitol, methacrylic acid copolymer, polysorbate 80, povidone, propylene glycol, sodium carbonate, sodium lauryl sulfate, titanium dioxide, and triethyl citrate.
