Omeprazole and Sodium Bicarbonate capsules are a combination of omeprazole, a proton-pump inhibitor, and sodium bicarbonate, an antacid. Omeprazole is a substituted benzimidazole, 5-methoxy-2- [[(4-methoxy-3,5-dimethyl-2-pyridinyl)methyl]sulfinyl]-1H-benzimidazole, a racemic mixture of two enantiomers that inhibits gastric acid secretion. Its empirical formula is C17H19N3O3S, with a molecular weight of 345.42. The structural formula is: Omeprazole is a white to off-white crystalline powder which melts with decomposition at about 155ºC. It is a weak base, freely soluble in ethanol and methanol, and slightly soluble in acetone and isopropanol and very slightly soluble 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 capsules are 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 capsule shell contains gelatin, titanium dioxide and the colorants FD&C Blue # 1, FD&C Red # 3, FD&C Red 40 and the components of blue imprinting edible ink are TekPrintTM SB-6003 Blue Ink (butyl alcohol, dehydrated alcohol, FD&C Blue # 2 aluminum lake, isopropyl alcohol, propylene glycol, shellac, strong ammonium 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.
