Mechanism of Action
Norfloxacin inhibits bacterial deoxyribonucleic acid synthesis and is bactericidal. At the molecular level, three specific events are attributed to norfloxacin in E. coli cells:
inhibition of the ATP-dependent DNA supercoiling reaction catalyzed by DNA gyrase, inhibition of the relaxation of supercoiled DNA, promotion of double-stranded DNA breakage.
