Interactions

May enhance the anticoagulant effect of vit K antagonists (e.g. warfarin). May diminish the therapeutic effect of Na picosulfate, BCG and typhoid vaccine. May decrease the protein binding of fosphenytoin and phenytoin. Probenecid may decrease renal tubular secretion of cefazolin, resulting in increased and prolonged blood levels. May increase the nephrotoxic effects of aminoglycosides.

Potentially Fatal: Anaphylaxis, pseudomembranous colitis.

Mechanism of Action

Cefazolin binds to 1 or more of the penicillin-binding proteins (PBPs) which inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell wall, thus inhibiting biosynthesis and arresting cell wall assembly resulting in bacterial cell death.
