NCIt definition : A broad-spectrum, third-generation cephalosporin antibiotic derived semisynthetically
from the marine fungus Cephalosporium acremonium with antibacterial activity. As does
penicillin, the beta-lactam antibiotic cefixime inhibits bacterial cell wall synthesis
by disrupting peptidoglycan synthesis, resulting in a reduction in bacterial cell
wall stability and bacterial cell lysis. Stable in the presence of a variety of beta-lactamases,
this agent is more active against gram-negative bacteria and less active against gram-positive
bacteria compared to second-generation cephalosporins.;
Alternative definition : NCI-GLOSS: An antibiotic drug used to treat infection. It belongs to the family of
drugs called cephalosporins.;
