Problems solved by technology

However, cefuroxime axetil is a lipophilic compound with poor water solubility and aggregates when exposed to water. The raw materials are unstable to humidity and heat. The existing dosage forms mainly include tablets, dispersible tablets, capsules, and dry suspensions. Conventional dosage forms such as tablets However, cefuroxime axetil tastes slightly bitter, and chewing it in the mouth can slightly irritate the oral mucosa, which makes patients resistant to the drug and reduces the Patient compliance with clinical medication

Abstract

The invention provides cefuroxime axetil composition freeze-dried orally disintegrating tablets and a preparation method of the orally disintegrating tablets, relates to the field of a medicine and a medicine preparation method technology and mainly solves the problems in the prior art that the cefuroxime axetil preparation is poor in curative effect and not suitable for children and the patients who are difficult to swallow. The cefuroxime axetil composition freeze-dried orally disintegrating tablets are prepared from the following components by weight: 25-50% of cefuroxime axetil, 25-75% of mannitol, 2-4% of gelatin, 0.1-0.15% of trichlorosucrose and 42-67% of tertiary butanol-water. The cefuroxime axetil composition freeze-dried orally disintegrating tablets prepared by the above components are easy in preparation process, and simple in components, and mainly meet the administration requirements of children and the patients who are difficult to swallow; moreover, the cefuroxime axetil composition freeze-dried orally disintegrating tablets have the advantages of being fast to disintegrate, convenient to take, and good in taste; and the tablets take effect quickly and are fully absorbed, and the first pass effect of the liver is avoided.

Description

Technical field: [0001] The invention relates to the technical field of medicines and preparation methods of medicines, in particular to a freeze-dried orally disintegrating tablet of a cefuroxime axetil composition and a preparation method thereof. Background technique: [0002] The chemical name of cefuroxime axetil is: (6R,7R)-7-[2-furyl(methoxyimino)acetamido]-3-carbamoyloxymethyl-8-oxo-5-thia- 1-Azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid, 1-acetoxyethyl ester. C20H22N4O10S, molecular weight 510.48, soluble in acetone, insoluble in water. Its chemical structural formula is: [0003] [0004] Cefuroxime axetil is an esterification preparation of the second-generation cephalosporin cefuroxime. After oral administration, it is decomposed by esterase in the intestinal mucosa and blood to form cefuroxime and its effect. It has a broad antibacterial spectrum and strong antibacterial activity, and has good antibacterial activity against both Gram-positive and Gram-negat...
