Ceforanide is a semi-synthetic, broad-spectrum, beta-lactam, second-generation cephalosporin antibiotic with bactericidal activity. Ceforanide causes inhibition of 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 the cell wall. This results in a reduction of cell wall stability and causes cell lysis.

4 Drug and Medication Information

4.1 Drug Indication

For the treatment of infections caused by susceptible organisms.

5 Pharmacology and Biochemistry

5.1 Pharmacology

Ceforanide is a semisynthetic second-generation cephalosporin. The cephalosporins are bactericidal drugs with both gram-positive and gram-negative activity. They inhibit bacterial cell wall synthesis in a way similar to the penicillins.

5.2 MeSH Pharmacological Classification

Anti-Bacterial Agents

Substances that inhibit the growth or reproduction of BACTERIA. (See all compounds classified as Anti-Bacterial Agents.)

5.3 ATC Code

J - Antiinfectives for systemic use

J01 - Antibacterials for systemic use

J01D - Other beta-lactam antibacterials

J01DC - Second-generation cephalosporins

J01DC11 - Ceforanide

5.4 Absorption, Distribution and Excretion

Absorption

Rapidly absorbed following intramuscular injection.

5.5 Metabolism/Metabolites

The major drug elimination route was urinary excretion with 85% of the dose being excreted unchanged in the urine within 12 hr, and no metabolites with antibiotic activity were observed in urine.

5.6 Biological Half-Life

2.6 to 2.98 hours

5.7 Mechanism of Action

The bactericidal activity of ceforanide results from the inhibition of cell wall synthesis via affinity for penicillin-binding proteins (PBPs).
