Pharmacology
- Indication
Used in the treatment of urinary tract infections caused by some strains of E. coli and klebsiella and enterobacter species. Used mainly against Gram negative organisms.
- Pharmacodynamics
Amdinocillin is a novel, semisynthetic penicillin effective against many gram-negative bacteria. The antibacterial activity of amdinocillin is derived from its ability to bind specifically and avidly to Penicillin Binding Protein-2 (PBP 2). Amdinocillin is active alone against many gram-negative organisms. Pseudomonas and non-fermenting gram-negative bacteria, however, are usually resistant. Amdinocillin, in combination with many beta-lactams, exhibits marked synergy against many enterobacteriaceae. No such synergy can be demonstrated for gram-positive organisms or pseudomonas species. Amdinocillin is not beta-lactamase stable. Organisms which produce high levels of plasma-mediated beta-lactamase are resistant to the drug. Co-administration of probenecid results in markedly elevated plasma levels of amdinocillin and delays its excretion.
- Mechanism of action
Amdinocillin is a stong and specific antagonist of Penicillin Binding Protein-2 (PBP 2). It is active against gram negative bacteria, preventing cell wall synthesis by inhibiting the activity of PBP2. PBP2 is a peptidoglycan elongation initiating enzyme. Peptidoglycan is a polymer of sugars and amino acids that is the main component of bacterial cell walls.
