Azactam, with the generic name aztreonam, is a synthetic monocyclic beta-lactam antibiotic specifically classified under the monobactam family. It is primarily used to combat a wide range of bacterial infections, including those affecting the urinary tract, lower respiratory tract, skin, abdomen, and female reproductive organs, as well as for septicemia. Azactam works by inhibiting bacterial cell wall synthesis, leading to the death of the bacteria. It is particularly effective against gram-negative bacteria and is often used in patients who are allergic to penicillin or cephalosporin antibiotics, as it tends to be well-tolerated with a lower risk of cross-allergenicity. Administered intravenously or intramuscularly, Azactam is a potent option in the arsenal against bacterial infections, especially in hospital settings or for severe infections that are resistant to other antibiotics.
