Abstract

The invention relates to a mosapride citrate tablet and a preparation method thereof, and belongs to the technical field of medical preparations which are applied to medical use and contain organic active ingredients. With mosapride citrate as a raw material and lactose, starch and hydroxypropyl methylcellulose as adjuvant materials, and assisted by aids, the mosapride citrate tablet is prepared by conducting wet-process granulation and tabletting. The mosapride citrate tablet provided by the invention, when applied to the preparation of gastric motor drugs, has the characteristics of being rapid in dissolution, good in stability, simple in preparation process, easy for industrial mass production and the like.

Description

technical field [0001] The application relates to a mosapride citrate tablet and a preparation method thereof, belonging to the technical field of medical preparations containing organic active ingredients. Background technique [0002] Mosapride citrate is a third-generation gastric motility drug developed by Nippon Pharmaceutical Co., Ltd. It is a selective 5-HT4 receptor agonist and belongs to the third-generation gastric motility drug, mainly used for the treatment of functional dyspepsia and gastroesophageal reflux disease. The drug can significantly improve symptoms such as sourness and heartburn in patients with functional dyspepsia, and can accelerate gastric emptying and promote gastric and duodenal motility. At the same time, there are no side effects such as extrapyramidal reaction and diarrhea, and the tolerance is good. [0003] The chemical name of mosapride citrate is (±)-4-amino-5-chloro-2-ethoxy-N-{[4-(4-fluorobenzyl)-2-morphinyl]methyl }Toluamide citrate ...
