Therapeutic Class

4-Quinolone Antibiotic

Pharmacology

Levoxin contains Levofloxacin, the L-isomer of ofloxacin. It works by inhibiting bacterial DNA gyrase and topoisomerase IV, enzymes essential for DNA replication, transcription, repair, and recombination. This action disrupts bacterial cell division and results in bactericidal activity.

Levoxin exhibits excellent tissue penetration and has activity against a wide range of pathogens including:

• Streptococcus pneumoniae

• Haemophilus influenzae

• Staphylococcus aureus (non-MRSA)

• Escherichia coli

• Klebsiella spp.

It is particularly useful in infections where other antibiotics may fail due to resistance.

Indications

Levoxin 500 mg/100 ml is indicated for the treatment of:

• Respiratory tract infections: Acute bacterial sinusitis, acute exacerbations of chronic bronchitis, community-acquired pneumonia, and nosocomial pneumonia

• Skin and soft tissue infections: Uncomplicated and complicated infections

• Urinary tract infections: Uncomplicated and complicated infections

• Chronic bacterial prostatitis

Dosage and Administration

• Acute sinusitis: 500 mg once daily for 10–14 days

• Acute exacerbations of chronic bronchitis: 250–500 mg once daily for 7–10 days

• Community-acquired pneumonia: 500 mg once or twice daily for 7–14 days

• Nosocomial pneumonia: 750 mg once daily for 7–14 days

• Skin & soft tissue infections: 500 mg once or twice daily for 7–14 days

• Chronic prostatitis: 500 mg once daily for 28 days

• Urinary tract infections: 250 mg once daily for 7–10 days; 3 days for uncomplicated infections

Levoxin is administered orally, with or without food. Adequate fluid intake is recommended during therapy to prevent crystalluria.
