🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Norfloxacin inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, enzymes that are essential for DNA replication, transcription, repair, and recombination. By blocking these enzymes, norfloxacin prevents the supercoiling of bacterial DNA, leading to inhibition of bacterial growth and ultimately bacterial cell death. It is bactericidal against a wide range of gram-negative and gram-positive bacteria.
