Ceftizoxime

Ceftizoxime is a third-generation cephalosporin available for parenteral administration.[1] Unlike other third-generation cephalosporins, the whole C-3 side chain in ceftizoxime has been removed to prevent deactivation by hydrolytic enzymes. It rather resembles cefotaxime in its properties, but is not subject to metabolism. It was removed from the US Market in 2007.
