Abstract

The invention relates to a pharmaceutical composition containing ilaprazole sodium and a preparation method thereof. The pharmaceutical composition is prepared from the ilaprazole sodium and ilaprazole derivatives, wherein the ilaprazole derivatives comprise ilaprazole sulfone, ilaprazole thioether, ilaprazole carboxyl ylide, ilaprazole hydroxyl ylide, ilaprazole mercaptomethyl ylide, ilaprazole methyl ylide, ilaprazole thiocyanmethyl ylide, ilaprazole dithiodimer, ilaprazole trithiodimer and ilaprazole nitrogen oxide. The pharmaceutical composition can be used for treating peptic ulcer hemorrhage and stress ulcer, and preventing upper gastrointestinal hemorrhage caused by serious illnesses.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a pharmaceutical composition containing ilaprazole sodium and a preparation method thereof. Background technique [0002] Ilaprazole (Ilaprazole Sodium), chemical name: 5-(1 hydrogen-pyrrol-1-yl)-2~[[(4-methoxy-3-methyl)-2-pyridyl]-methanol Base]-sulfinyl-1 hydrogen-benzimidazole sodium salt. Ilaprazole is the latest generation of proton pump inhibitor (PPI) developed and marketed by Livzon Group, which is widely used in various acid-related gastrointestinal diseases, such as duodenal ulcer, gastric ulcer and reflux esophagitis Wait. Compared with other PPIs, ilaprazole has the strongest antacid activity, no individual differences in treatment, and stronger ability to control acid at night, and is expected to become a core product in the PPI market. [0003] Chinese patents CN1184970C and CN1225240C respectively disclose ilaprazole oral tablet and its microparticle preparatio...
