Indications & Uses
Reonam is indicated for:
Pharmacology
Aztreonam is a synthetic monobactam antibiotic that kills bacteria by stopping the synthesis of their cell walls. It works by binding strongly to penicillin binding protein 3 (PBP3), which blocks the final stage of peptidoglycan crosslinking, the process that holds the bacterial cell wall together. With PBP3 blocked, the bacterium's own cell wall enzymes, known as autolysins, go on to break down the wall and cause the cell to rupture. Aztreonam may also work by interfering with a natural inhibitor of these autolysins.
