Problems solved by technology

[0007] But, because the viscosity of ceftazidime pivoxil hydrochloride raw material is too strong, and chemical performance is unstable under high temperature and high humidity conditions
Based on this point, the prior art generally believes that the wet granulation process is not only difficult to make granules, but also the active ingredients contained are easily degraded during the granulation and drying process

Abstract

The invention discloses a cefetamet pivoxil hydrochloride tablet and a preparation method thereof. On the premise of specific active ingredients of the cefetamet pivoxil hydrochloride, the invention takes into account the varieties and dosages of disintegrating agents and joint usage thereof, suitable components and ratios of bonding agents and other filling agents, and the micronization treatment of the raw and auxiliary materials and selection of corresponding optimized process conditions. Experiment results indicate that compared with the prior art, the product of the invention has quick disintegration and dissolution and stable quality.

Description

technical field [0001] The invention relates to a ceftazidime hydrochloride dispersible tablet and a preparation method of the dispersible tablet. Background technique [0002] In the prior art, β-lactam antibiotics are the most clinically used antibiotics, the most widely used, the most varieties, the best curative effect and the highest evaluation. Among them, cephalosporin series products account for about 70%. Among cephalosporins, ceftazidime pivoxil hydrochloride is an oral third-generation broad-spectrum cephalosporin antibiotic, which has the characteristics of broad-spectrum, high efficiency, enzyme resistance, and low toxicity. Compared with similar varieties of cephalexin and cephradine, it has antibacterial With the advantages of stronger activity and smaller dose, it overcomes the shortcomings of Pioneer series products that are unstable to β-lactamase, and is an ideal substitute for cephalexin and cephradine. [0003] On the market, ceftazidime pivoxil prepara...
