The active ingredient in pantoprazole sodium delayed-release tablets, USP is a substituted benzimidazole, sodium 5-(difluoromethoxy)-2-[[(3,4-dimethoxy-2-pyridinyl) methyl] sulfinyl]- 1H -benzimidazole sesquihydrate, a compound that inhibits gastric acid secretion. Its empirical formula is C 16 H 14 F 2 N 3 NaO 4 S x 1.5 H 2 O, with a molecular weight of 432.4. The structural formula is: Pantoprazole sodium (sesquihydrate), USP is a white to off-white crystalline powder and is racemic. Pantoprazole has weakly basic and acidic properties. Pantoprazole sodium (sesquihydrate), USP is freely soluble in water, very slightly soluble in phosphate buffer at pH 7.4, and practically insoluble in n-hexane. The stability of the compound in aqueous solution is pH-dependent. The rate of degradation increases with decreasing pH. At ambient temperature, the degradation half-life is approximately 2.8 hours at pH 5 and approximately 220 hours at pH 7.8. Pantoprazole sodium is supplied as a delayed-release tablet, available in two strengths (20 mg and 40 mg). Each pantoprazole sodium delayed-release tablet, USP contains 45.1 mg or 22.55 mg of pantoprazole sodium (sesquihydrate), USP (equivalent to 40 mg or 20 mg pantoprazole, respectively) with the following inactive ingredients: calcium stearate, crospovidone, hydroxypropyl cellulose, hypromellose, mannitol, methacrylic acid copolymer dispersion, propylene glycol, sodium carbonate, talc, titanium dioxide, and triethyl citrate. Pantoprazole sodium delayed-release tablets, USP, 20 mg and 40 mg meet USP dissolution test 3. Image
