Omeprazole and sodium bicarbonate is a combination of omeprazole, a proton-pump inhibitor, and sodium bicarbonate, an antacid. Omeprazole is a substituted benzimidazole, 5-methoxy-2- [[(4-methoxy-3,5dimethyl-2-pyridinyl)methyl]sulfinyl]-1 H-benzimidazole, a racemic mixture of two enantiomers that inhibits gastric acid secretion. Its empirical formula is C 17H 19N 3O 3S, with a molecular weight of 345.42. The structural formula is: Omeprazole, USP is a white or almost white powder which melts with decomposition at about 155°C. Soluble in dichloromethane, practically insoluble in water. The stability of omeprazole is a function of pH; it is rapidly degraded in acid media but has acceptable stability under alkaline conditions. Omeprazole and sodium bicarbonate is supplied as immediate-release capsules. Each capsule contains either 40 mg or 20 mg of omeprazole and 1100 mg of sodium bicarbonate with the following excipients: croscarmellose sodium and sodium stearyl fumarate. The capsules consist of gelatin and titanium dioxide. In addition the 20 mg/1100 mg capsule shell contains sodium lauryl sulfate and the 40 mg/1100 mg capsule shell contains FD&C Blue 1. The capsules are printed with edible ink containing black iron oxide, butyl alcohol, dehydrated alcohol, isopropyl alcohol, propylene glycol, potassium hydroxide, shellac and strong ammonia solution. Omeprazole and sodium bicarbonate capsules are immediate-release formulations that contain sodium bicarbonate which raises the gastric pH and thus protects omeprazole from acid degradation. STR
