🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Norfloxacin, the active ingredient in this medicine, is a synthetic broad-spectrum fluoroquinolone antibiotic. It exerts its bactericidal effect by inhibiting two essential bacterial enzymes: DNA gyrase (topoisomerase II) and topoisomerase IV. DNA gyrase is responsible for introducing negative supercoils into DNA, relieving topological stress during replication, while topoisomerase IV is involved in decatenation of interlinked DNA strands. By binding to these enzymes, norfloxacin stabilizes the enzyme-DNA complex, blocking DNA replication, transcription, repair, and recombination. This leads to rapid bacterial cell death. Norfloxacin is active against a wide range of gram-negative and gram-positive bacteria, including Pseudomonas aeruginosa, but has limited activity against anaerobes.
