Abstract

The invention provides a cefixime oral preparation. The cefixime oral preparation comprises the following components in percentage by weight: 30 to 200 parts of cefixime as an active ingredient, 500 to 1000 parts of a filler, 30 to 80 parts of a suspending agent, 5 to 30 parts of a binding agent, and 0.4 to 5 parts of a lubricating agent. The cefixime oral preparation prepared by the invention is good in suspension effect and dissolubility, and the dissolution rate of the cefixime oral preparation reaches 95% and more than 95%. Furthermore, the cefixime oral preparation is high in bioavailability, solves the defects of poor solubility of the active ingredients and low bioavailability, and has stable quality and reliability, thereby extremely having market development prospects.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations and relates to an oral preparation of cefixime. The invention also provides an oral preparation of cefixime with good quality, safety and stability. Background technique [0002] Cefixime is white to light yellow crystalline powder, odorless, with slight specific odor, easily soluble in methanol, dimethyl sulfoxide, slightly soluble in acetone, hardly soluble in ethanol, almost insoluble in water, ethyl acetate, ether, in hexane. As the third-generation oral cephalosporin antibiotic, cefixime has a broad antibacterial spectrum and strong antibacterial activity. , Proteus mirabilis, and Neisseria gonorrhoeae (including enzyme-producing strains) all have good antibacterial activity, are stable to most β-lactamases, and have the advantages of small side effects. Streptococcus (except Enterococcus), pneumococcus, Neisseria gonorrhoeae, Branhamella catarrhalis, Escherichia coli, K...
