What is the difference between azithromycin and other antibiotics?
Azithromycin belongs to a class of antibiotics called macrolides [2]. Macrolides work by preventing bacteria from producing proteins essential for their growth and reproduction [2]. This mechanism of action distinguishes it from other antibiotic classes, such as penicillins, which target bacterial cell wall synthesis, or fluoroquinolones, which interfere with DNA replication [3]. Azithromycin's pharmacokinetic profile also means it can be dosed less frequently than many other antibiotics [2].
