Abstract

The invention discloses a pantoprazole sodium-containing enteric-coated tablet and a preparation method thereof. The enteric-coated tablet is obtained by sequentially coating a tablet core with an isolating coating and an enteric coating, wherein the tablet core is formed by evenly mixing medicine-containing granules with a filler and a lubricant and then directly tabletting, and a preparation method of the medicine-containing granules comprises the following steps of: dissolving pantoprazole sodium into absolute ethyl alcohol, adding polacrilin potassium, drying and volatilizing to remove ethanol, and sieving dried materials. The varieties of auxiliary materials are fewer, the drug release is fast, the stability of the preparation is high, the production technology is simple, no sticking phenomenon exists in tabletting, and the industrial production is easy.

Description

technical field [0001] The invention belongs to the technical field of chemical preparations, and in particular relates to a solid oral preparation of pantoprazole sodium, in particular to an enteric-coated tablet containing pantoprazole sodium and a preparation method thereof. Background technique [0002] Pantoprazole sodium (PAZ-Na) is a new generation of proton pump inhibitors after omeprazole and lansoprazole. + / K + -ATPase inhibits gastric acid secretion, and mainly treats duodenal ulcer, gastric ulcer, Zoller's syndrome and reflux esophagitis. Pantoprazole is one of several common proton pump inhibitors (PPI) on the market at present, according to literature reports, the bioavailability of pantoprazole is 7 times higher than omeprazole, and the selectivity to parietal cells is more dedicated. Pantoprazole is a dialkoxypyridylbenzimidazole compound with good target specificity and acid stability, and daily oral standard dose (40mg) of pantoprazole can inhibit 98% o...
