Abstract

The invention discloses a cefuroxime axetil tablet and a preparation method thereof. The cefuroxime axetil tablet is characterized by comprising the following components: cefuroxime axetil, starch, lactose, micropowder silica gel, a 2% hydroxypropyl methyl cellulose aqueous solution, sodium carboxymethyl starch and magnesium stearate, and the cefuroxime axetil tablet is prepared by reasonably allocating a proportion of the components according to a wet method pelleting tabletting technology. The method solves the problems that cefuroxime axetil meets water or alcohol to generate very high viscosity, and dry method pelleting tabletting or direct powder tabletting can only by adopted generally; special equipment and special auxiliary materials are not required; a qualification rate is high in a production process; and the production cost is lowered.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to a cefuroxime axetil tablet and a preparation method thereof. Background technique [0002] Cefuroxime axetil (Ceftin) is a second-generation semi-synthetic cephalosporin created by GlaxoSmithKline. It has the characteristics of human pharmacokinetics, high blood concentration, can penetrate into sputum, bone tissue and inflammatory cerebrospinal fluid, has little nephrotoxicity, and can be administered orally. [0003] A number of cefuroxime axetil tablets have been launched in China, mainly Xilixin (GlaxoSmithKline), North China Pharmaceutical, Shenzhen Zhijun and other brands. Due to the very strong viscosity of cefuroxime axetil when it meets water or ethanol, manufacturers at home and abroad generally believe that wet granulation cannot be used for tabletting, and instead adopt dry granulation or full powder tabletting. [0004] The preparation method of dry granu...
