Problems solved by technology

[0004] The quality of cefaclor raw materials is unstable and easy to degrade under humid and hot conditions. Therefore, the quality stability of cefaclor preparations currently on the market is generally poor, and the preparations need to be kept away from light and sealed.
In addition, because cefaclor is slightly soluble in water, its granules usually have the problem of poor suspension effect. After adding a certain amount of water to dissolve, the suspension effect of the solution is poor and stratification occurs, and it is difficult to ensure the dosage when taking it. affect the efficacy of the drug

Abstract

The invention discloses a cefaclor granule and a preparation method thereof. The cefaclor granule is prepared by mixing a cefaclor granule clathrate compound with pharmaceutically acceptable auxiliary materials. The cefaclor granule clathrate compound is prepared by following steps: dissolving polyvinyl alcohol-polyethylene glycol graft copolymer (Kollicoat IR) in ethanol; adding cefaclor in the solution; and keeping stirring the solution and removing ethanol by vacuum drying method so as to obtain the cefaclor granule clathrate compound. Stability and dissolution rate of the cefaclor granule are high, production technology is simple, and the cefaclor granule is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a cefaclor granule and a preparation method thereof. Background technique [0002] Cephalosporins play a bactericidal effect by inhibiting bacterial cell wall synthesis and are stable to most β-lactamases. Many strains producing penicillinase and cephalosporinase are still sensitive to cephalosporins. Cephalosporins in vitro and in vivo against Gram-positive cocci such as pneumococcus, Streptococcus pyogenes, Gram-negative bacilli such as influenza bacilli (including enzyme-producing strains), Moraxella catarrhalis (including enzyme-producing strains) , Escherichia coli, Proteus mirabilis, and Neisseria gonorrhoeae (including enzyme-producing strains) all have good antibacterial effects. Effects of cephalosporins on Streptococcus pneumoniae, Bacillus parainfluenzae, Proteus vulgaris, Klebsiella pneumoniae, Pasteurella multocida, Providencia sp., Salmonella sp., Shig...
