Abstract
The invention provides a compound preparation containing vonoprazan and non-steroidal anti-inflammatory drugs. The compound preparation is characterized by being an inner-outer multi-layer preparation prepared from the vonoprazan and one or more than one non-steroidal anti-inflammatory drugs; an isolation layer is arranged between the inner-layer drug and the outer-layer drug to prevent contact of the vonoprazan and the non-steroidal anti-inflammatory drugs. The vonoprazan can inhibit gastric acid secretion, improve the clinical symptoms such as gastric acid increasing and epigastrium pain, reduce the pessimal stimulation of the non-steroidal anti-inflammatory drugs such as aspirin to the stomach and significantly reduce the occurrence rate of gastric mucosal erosion and anabrosis, and therefore the protective effect on the stomach is achieved.
Description
technical field [0001] The invention relates to the field of medicine, in particular to a compound preparation prepared by a specific process from vonoprazan, non-steroidal anti-inflammatory drugs and pharmaceutical excipients. Background technique [0002] Vonorazan was developed by Japan's Takeda Pharmaceutical Co., Ltd. and is a new type of gastric acid secretion inhibitor. The specific structural formula is as follows: [0003] [0004] In the final step of gastric acid secretion from parietal cells, it can competitively inhibit the combination of potassium ions and hydrogen-potassium ATPase, and thus is classified as a potassium-competitive acid inhibitor (P-CAB). Vonorazan has a strong and long-lasting inhibitory effect on gastric acid secretion, and can inhibit the recurrence of gastric ulcer or duodenal ulcer caused by low-dose aspirin and non-steroidal anti-inflammatory drugs. [0005] Currently, proton pump inhibitors (PPIs) are widely prescribed for the first-...
