Aztreonam + Avibactam injection is a combination of a monobactam β-lactam antibiotic and a β-lactamase inhibitor. The combination is particularly important when discussing difficult-to-treat Gram-negative bacteria and resistance mechanisms involving metallo-β-lactamases (MBLs) together with other β-lactamases. Aztreonam and avibactam have different but complementary roles. Aztreonam provides the antibacterial activity, while avibactam inhibits several susceptible β-lactamases...Read More
