Abstract:
with 7-amino-3-deacetoxycephalosporanic acid (7-ADCA) as the mother nucleus and p-hydroxyphenylglycine methyl ester (HPGME) as the acyl donor, in the phosphate buffer system, synthesis of cefadroxil catalyzed by immobilized penicillin acylase. Through the investigation of the influencing factors in the enzymatic synthesis of cefadroxil, the better synthesis conditions were selected. The results showed that the reaction temperature was 25 C, the reaction system pH 6.5,7-ADCA,HPGME and Immobilized enzyme dosage were 2.5%,7.5%,1.5%, the conversion of the synthetic reaction can reach 80.3%.

Abstract:
The present invention discloses a cefadroxil tablet for pet use and a preparation method thereof. Each tablet contains cefadroxil including but not limited to 0.125g,0.25g and 0.5g. The cefadroxil tablet for pets comprises the following components in parts by weight: cefadroxil 25-42%, bulking agent 30-60%, disintegrating agent 3-12%, flavoring agent 0.1-1%, lubricant 1-5%. The cefoxitin tablets for pets of the present invention are directly compressed by dry method, which avoids the production conditions of high temperature and high humidity compared with the existing products on the market, under the conditions of high humidity and the like, the content and related substances have no obvious change, and the stability is better; And the in vitro dissolution test shows that the dissolution rate of the cefoxitin benzyl tablets for pets provided by the present invention is obviously better than that of the commercially available products, it shows that the bioavailability of this product is better. The invention of cefoxitin benzyl tablets, stability, good curative effect
