Abstract

The invention provides a method for preparing novel cefixime tablets and cefixime capsules. In the method, cefixime, a solubilizer and water soluble auxiliary materials are micronized and then mixed with other auxiliary materials, and the obtained products are granulated by a dry method, so that the stability of cefixime tablets and cefixime capsules is improved, and the dissolution rate of cefixime is also raised. The cefixime can be quickly absorbed by a patient after the patient takes the cefixime tablets and cefixime capsules, the plasma peak time is shortened and the plasma concentration can be quickly stabilized at a higher level, so that the treating effect is improved.

Description

technical field [0001] The invention relates to a new preparation method of cefixime tablets and capsules, belonging to the field of pharmaceutical preparations. Background technique [0002] Cefixime (cefixime) is an oral third-generation cephalosporin antibiotic, developed by Japan Fujisawa Co., Ltd., and first listed in Japan in 1987 by Japan Fujisawa Pharmaceutical Co., Ltd., with a trade name of Cefspan. Cefixime has the following characteristics: broad antibacterial spectrum, it has spectrum antibacterial effect on Gram-positive bacteria and negative bacteria; long half-life, can be taken only once or twice a day, easy to use; less cross-resistance It is extremely stable to the β-lactamase produced by various bacteria, and can effectively inhibit or kill Serratia, Enterobacter, Proteus, etc. that are clinically resistant to other cephalosporin antibiotics; the dose is small, and the body is widely distributed. High curative effect, low cost of use, strong market compe...
