Cirrofloxacin is an antibiotic belonging to the fluoroquinolone class, primarily used to treat bacterial infections. It works by inhibiting bacterial DNA gyrase and topoisomerase IV, enzymes essential for bacterial DNA replication and repair. While effective against a range of pathogens, its use is often limited due to potential side effects and the emergence of antibiotic resistance. It is important to use cirrofloxacin and other antibiotics judiciously to preserve their effectiveness.
