Cefoperazone; Uses, Dosage, Side effects, Interactions

Cefoperazone is a semisynthetic, broad-spectrum, third-generation cephalosporin with antibacterial activity. Cefoperazone 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 Cefoperazone

The bactericidal activity of  Ceftizoxime results from the inhibition of cell wall synthesis via affinity for penicillin-binding proteins (PBPs). Ceftizoxime is 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. Cefoperazone Sodium is the sodium salt form of cefoperazone and a semi-synthetic, broad-spectrum, beta-lactamase resistant, third-generation cephalosporin antibiotic with bactericidal activity. Cefoperazone sodium inhibits bacterial cell wall synthesis by inactivating penicillin-binding proteins (PBPs) thereby interfering with the final transpeptidation step required for cross-linking of peptidoglycan units which are a component of bacterial cell walls. This results in a reduction of cell wall stability and causes cell lysis.
