pantoprazole sodium in 0.9% sodium chloride - Generic Medications

The active ingredient in pantoprazole sodium in 0.9% sodium chloride injection, a PPI, is a substituted benzimidazole, sodium 5-(difluoromethoxy)-2-[[(3,4-dimethoxy-2-pyridinyl)methyl] sulfinyl]-1 H -benzimidazole, a compound that inhibits gastric acid secretion. Its empirical formula is C16H14F2N3NaO4S, with a molecular weight of 405.4. The structural formula is: Pantoprazole sodium is a white to off-white crystalline powder and is racemic. Pantoprazole has weakly basic and acidic properties. Pantoprazole sodium 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. The thawed solution of pantoprazole sodium in 0.9% sodium chloride injection is in the pH range 9.0 to 10.5. Pantoprazole sodium in 0.9% sodium chloride injection is supplied for intravenous administration as a frozen, premixed, iso-osmotic, sterile, nonpyrogenic 50 mL or 100 mL single-dose GALAXY container in following presentations: 40 mg/100 mL (0.4 mg/mL): containing 40 mg of pantoprazole (equivalent to 45.1 mg of pantoprazole sodium USP); 1 mg edetate disodium, USP; 155 mg histidine, USP; 900 mg sodium chloride, USP; 40 mg/50 mL (0.8 mg/mL): containing 40 mg of pantoprazole (equivalent to 45.1 mg of pantoprazole sodium USP); 1 mg edetate disodium, USP; 77.5 mg histidine, USP; 450 mg sodium chloride, USP; 80 mg/100 mL (0.8 mg/mL): containing 80 mg of pantoprazole (equivalent to 90.2 mg of pantoprazole sodium USP); 2 mg edetate disodium, USP; 155 mg histidine, USP; 900 mg sodium chloride, USP; Sodium hydroxide and/or hydrochloric acid may be used to adjust pH. The solution is intended for intravenous use after thawing to room temperature. Thawed solution is expected to range from colorless to yellow over time. Pantoprazole Structural Formula
