Floromox 400 mg Tablet contains Moxifloxacin Hydrochloride, a fourth-generation fluoroquinolone antibiotic. It is effective against a broad spectrum of gram-positive, gram-negative, anaerobic, and atypical bacteria. Moxifloxacin works by inhibiting bacterial enzymes DNA gyrase and topoisomerase IV, which are essential for DNA replication, transcription, and repair, leading to bacterial cell death.
