Norfloxacin 0.3% Eye DropsThird Party Manufacturing in India

Norfloxacin is a synthetic broad-spectrum fluoroquinolone antibiotic that works by inhibiting bacterial DNA synthesis. It targets two essential bacterial enzymes: DNA gyrase (topoisomerase II) and topoisomerase IV. By binding to these enzymes, norfloxacin prevents the supercoiling and relaxation of bacterial DNA, blocking DNA replication, transcription, and repair. This dual-enzyme inhibition makes it bactericidal at therapeutic concentrations. The fluorine atom at the 6-position enhances potency against gram-negative organisms, while the piperazine moiety at the 7-position provides activity against Pseudomonas aeruginosa. Norfloxacin shows minimal cross-resistance with other antibiotic classes and remains effective against bacteria that have developed resistance to non-fluoroquinolone agents.
