Problems solved by technology

[0003] At present, most of the cefdinir drugs produced in China are capsules and dispersible tablets, which are not convenient for patients to take, especially for the elderly, children and other patients who have difficulty swallowing
In addition, because the cefdinir raw material is more insoluble in water, the bioavailability and stability of cefdinir drugs are lower, therefore, how to develop a kind of cefdinir with higher bioavailability and stability and convenient for patients to take Nepalese medicine has become a problem to be solved urgently in this field

Abstract

The invention provides a cefdinir (C14H13N5O5S2), citric acid and sodium citrate dry suspension composition and a preparation method thereof. The cefdinir, citric acid and sodium citrate dry suspension composition comprises the following components in parts by weight: 100 parts of cefdinir, 1900-2100 parts of a diluent, 120-200 parts of a flocculant, 28-35 parts of a corrigent, 185-195 parts of an adhesive, 15-30 parts of a suspending aid, 8-12 parts of a flow aid and 1.5-2.5 parts of a lubricant. The cefdinir, citric acid and sodium citrate dry suspension composition disclosed by the invention is convenient for being taken by patients, and has high bioavailability and stability.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to a cefdinir (C 14 h 13 N 5 o 5 S 2 ) and citric acid and sodium citrate dry suspension composition. Background technique [0002] Cefdinir is a new generation of cephalosporin 3rd generation oral antibiotics, first synthesized in 1988, began to be used in Japan in 1991, was approved by the US FDA in December 1997, and began to be used in the United States. Because cefdinir is well absorbed orally, with few adverse reactions and broad antibacterial spectrum, it is not only effective against Gram-negative bacteria (G-), but also has high antibacterial activity against Gram-positive bacteria (G+), so it is widely used in clinical application. As for cefdinir drugs, there are "Quanzefu Capsules" produced by Xi'an Janssen and "Shifuni Capsules" produced by Tianjin Central Pharmaceutical Co., Ltd. on the domestic market. [0003] At present, domestically produced cefdin...
