EMBLAVEO Powder for solution for infusion Ref.[110084] Active ingredients: Avibactam Aztreonam Aztreonam and Avibactam

Aztreonam exhibits activity in vitro against gram-negative aerobic pathogens, including P. aeruginosa. Aztreonam binds to penicillin-binding proteins of susceptible bacteria, which leads to inhibition of bacterial cell wall synthesis, followed by filamentation and cell lysis.

Aztreonam inhibits bacterial peptidoglycan cell wall synthesis following binding to penicillin-binding proteins (PBPs), which leads to bacterial cell lysis and death. Avibactam is a non β-lactam, β-lactamase inhibitor that acts by forming a covalent adduct with the enzyme that is stable to hydrolysis. Avibactam inhibits both Ambler class A and class C β-lactamases and some class D enzymes, including extended-spectrum β-lactamases (ESBLs), Klebsiella pneumoniae carbapenemase (KPC) and OXA-48 carbapenemases, and AmpC enzymes.
