Therapeutic Class

4-Quinolone Antibiotic / Fluoroquinolone

Pharmacology

Levoxin 500 mg is a third-generation, synthetic, chiral fluoroquinolone. Its antibacterial activity is achieved through inhibition of bacterial DNA gyrase and topoisomerase IV, enzymes crucial for DNA replication, transcription, and repair. By disrupting these processes, Levoxin effectively halts bacterial growth and induces cell death.

It exhibits in vitro activity against a wide spectrum of bacteria, including:

• Gram-negative organisms such as Escherichia coli, Klebsiella spp., Pseudomonas aeruginosa

• Gram-positive organisms such as Streptococcus pneumoniae, Staphylococcus aureus

Levoxin is rapidly absorbed after oral administration, achieving therapeutic concentrations in blood and tissues, including the lungs, urinary tract, and prostate.
