indication

For the treatment of bacterial infections caused by susceptible microorganisms.

pharmacology

Cefonicid is a second-generation cephalosporin administered intravenously or intramuscularly. Its bactericidal action results from inhibition of cell wall synthesis. It is used for urinary tract infections, lower respiratory tract infections, and soft tissue and bone infections.

mechanism of action

Cefonicid, like the penicillins, is a beta-lactam antibiotic. By binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, it inhibits the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins.

biotransformation

Not metabolized.

half life

4.5 hours

drug interactions
