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.

Drug Interaction Integrate drug-drug
interactions in your softwareAcemetacin Acemetacin may decrease the excretion rate of Amdinocillin which could result in a higher serum level. Acenocoumarol Amdinocillin may increase the anticoagulant activities of Acenocoumarol. Ambroxol The risk or severity of methemoglobinemia can be increased when Amdinocillin is combined with Ambroxol. Amikacin The serum concentration of Amikacin can be decreased when it is combined with Amdinocillin. Articaine The risk or severity of methemoglobinemia can be increased when Amdinocillin is combined with Articaine. - Food Interactions
