`Laboratory Chemical Safety Summary (LCSS)
`
`Norfloxacin is a synthetic fluoroquinolone (FLUOROQUINOLONES) with broad-spectrum antibacterial activity against most
`gram-negative and gram—positive bacteria. Norfloxacin inhibits bacterial DNA GYRASE.
`
`> from MeSH
`
`Norfloxacin is a Quinolone Antimicrobial. The chemical classification of norfloxacin is Quinolones.
`
`> FDA Pharmacology Summary from FDA Pharm Classes
`
`Norfloxacin is a synthetic, broad-spectrum fluoroquinolone with antibacterial activity. Norfloxacin inhibits activity of DNA
`gyrase, thereby blocking bacterial DNA replication. Norfloxacin concentrates in the renal tubules and bladder and is
`bactericidal against a wide range of aerobic gram-positive and gram—negative organisms.
