Problems solved by technology

However, the cefcapene hydrochloride tablets prepared according to the composition of the above auxiliary materials still have disintegration difficulties, resulting in unqualified dissolution rate
[0007] At present, the preparation of cefcapene pivoxil granules is to directly prepare drug-containing pellets with a centrifugal coating granulator after mixing the raw materials and auxiliary materials. However, the yield of the finished product is low because of the dust flying during the granulation and the loss is relatively large. , how to overcome the above problems is the focus of research in recent years

Abstract

The invention relates to the technical field of medicine, in particular to a cefcapene pivoxil hydrochloride granule and a preparation method thereof. The cefcapene pivoxil hydrochloride granule comprises cefcapene pivoxil hydrochloride, microcrystalline cellulose, mannitol, croscarmellose sodium, hydroxypropyl methylcellulose, talcum powder and steviosin. The obtained cefcapene pivoxil hydrochloride granule is good in stability, rapid in disintegration, good in taste and good in curative effect, and has an obvious anti-inflammatory effect which is remarkably higher than inflammatory effect inthe prior art.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to a cefcapene hydrochloride granule and a preparation method thereof. Background technique [0002] Cefcapene pivoxil hydrochloride (cefcapene pivoxil hydrochloride), its chemical name is (6R, 7R)-7-[(Z)-2-(2-aminothiazol-4-yl)-2-pentenylamino]-3 -[(aminocarbonyl)oxy]methyl-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid (2,2-dimethyl Oxypropoxymethyl) ester hydrochloride monohydrate, its structural formula is as follows: [0003] [0004] Cefcapene pivoxil hydrochloride was developed by Shionogi Co., Ltd. of Japan.
