Abstract
Desacetyl-cefotaxime, the main metabolite of cefotaxime, possesses a broad antibacterial spectrum. Its activity is lower than that of cefotaxime, but significantly surpasses that of cefazolin against gram-negative bacteria. The β-lactamase stability of desacetyl-cefotaxime is higher than that of the parent compound. This β-lactamase stability might be responsible for the synergistic effects of cefotaxime and desacetyl-cefotaxime occasionally seen inin vitro combination studies. Desacetyl-Cefotaxim, der Hauptmetabolit von Cefotaxim, besitzt ein breites Wirkungsspektrum. In seiner antibakteriellen Aktivität ist es dem Cefotaxim zwar unterlegen, übertrifft aber Cefazolin bei den gramnegativen Erregern deutlich. Die β-Laktamasestabilität von Desacetyl-Cefotaxim ist noch höher als die der Ausgangssubstanz. Diese β-Laktamasestabilität ist möglicherweise der Grund für den inin vitro Kombinationsversuchen gelegentlich nachweisbaren synergistischen Effekt von Cefotaxim und Desacetyl-Cefotaxim.This publication has 11 references indexed in Scilit:
