Cefetamet is a semisynthetic, beta-lactamase-stable, third-generation cephalosporin with antibacterial activity. Cefetamet binds to and inactivates penicillin-binding proteins (PBPs) located on the inner membrane of the bacterial cell wall. PBPs are enzymes involved in the terminal stages of assembling the bacterial cell wall and in reshaping the cell wall during growth and division. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity. This results in the weakening of the bacterial cell wall and causes cell lysis.
Mechanism of Action of Cefetamet
The bactericidal activity of cefetamet results from the inhibition of cell wall synthesis via affinity for penicillin-binding proteins (PBPs). Cefetamet highly resistant to a broad spectrum of beta-lactamases and is active against a wide range of both aerobic and anaerobic gram-positive and gram-negative organisms.
