Mechanism of Action Ofloxacin is a broad-spectrum fluoroquinolone antibiotic that inhibits bacterial DNA gyrase and topoisomerase IV enzymes. These enzymes are essential for bacterial DNA replication, transcription, and repair. By blocking these enzymes, Ofloxacin causes double-strand DNA breaks, leading to rapid bactericidal activity against a wide range of Gram-positive and Gram-negative organisms, as well as atypical pathogens.
