Ceftizoxime is a third-generation cephalosporin available for parenteral administration. 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.

Synthesis

Injectable third generation cephalosporin antibiotic related to cefotaxime, q.v. Exhibits broad spectrum activity and resistance to β-lactamase hydrolysis.
