Cefpiramide is a third-generation, semi-synthetic, beta-lactam cephalosporin antibiotic with antibacterial activity. Cefpiramide binds to penicillin-binding proteins (PBPs), transpeptidases that are responsible for crosslinking of peptidoglycan. By preventing crosslinking of peptidoglycan, cell wall integrity is lost and cell wall synthesis is halted.

4 Drug and Medication Information

4.1 Drug Indication

For treatment of severe infections caused by susceptible bacteria such as P. aeruginosa.

5 Pharmacology and Biochemistry

5.1 Pharmacology

Cefpiramide is a cephalosporin active against Pseudomonas aeruginosa. It has a broad spectrum of antibacterial activity. Cefpiramide works by inhibiting bacterial cell wall biosynthesis. The plasma half-lives of cefpiramide in rabbits, dogs, and rhesus monkeys were much longer than those of cefoperazone and cefazolin.

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

J01DD - Third-generation cephalosporins

J01DD11 - Cefpiramide
