Therapeutic Class

4-Quinolone Antibiotic / Fluoroquinolone

Pharmacology

Levoxin 250 mg is a synthetic chiral fluorinated carboxyquinolone. It exerts its antibacterial effect by inhibiting:

• DNA gyrase – preventing DNA supercoiling

• Topoisomerase IV – blocking DNA replication and repair

This dual mechanism results in rapid bacterial cell death, making Levoxin effective against pathogens including:

• Gram-negative bacteria: E. coli, Klebsiella spp., Pseudomonas aeruginosa

• Gram-positive bacteria: Streptococcus pneumoniae, Staphylococcus aureus

Levoxin is well absorbed orally, achieving therapeutic levels in tissues such as the lungs, urinary tract, and skin.
