Levofloxacine Arrow (Levofloxacin Hemihydrate)

Levofloxacin is a fluoroquinolone antibiotic that interferes with bacterial DNA replication, making it effective for several serious infections.

• Community‑acquired pneumonia: eradicates the causative bacteria, leading to clinical improvement and resolution of infection.
• Complicated urinary tract infections: eliminates pathogenic organisms, facilitating recovery of urinary tract function.
• Skin and soft‑tissue infections: clears bacterial load, promoting healing of affected tissues.
• Intra‑abdominal infections: targets mixed bacterial flora, aiding resolution of intra‑abdominal sepsis.
• Prostatitis: reduces bacterial burden in prostatic tissue, improving symptoms.
• Acute bacterial sinusitis: resolves sinus infection by killing the responsible bacteria.

• Levofloxacin inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, enzymes essential for DNA supercoiling and replication. By binding to these enzymes, it prevents the unwinding and resealing of DNA strands, thereby halting bacterial DNA synthesis, transcription, and cell division, which leads to bacterial cell death.

Levofloxacine Arrow may cause a range of adverse reactions.

Common Side Effects

• Nausea: mild to moderate stomach upset.
• Diarrhea: loose stools, sometimes watery.
• Headache: transient cranial discomfort.
• Dizziness: sensation of light‑headedness.
• Rash: mild skin erythema or itching.
• Elevated liver enzymes: transient increase in hepatic transaminases.

Serious or Rare Side Effects

• Tendon rupture: especially Achilles tendon, may occur without warning.
• QT interval prolongation: can precipitate cardiac arrhythmias.
• Clostridioides difficile infection: severe colitis following disruption of gut flora.
• Severe allergic reactions: anaphylaxis, angioedema, or Stevens‑Johnson syndrome.
• Hepatic failure: rare but potentially life‑threatening liver injury.
• Seizures: central nervous system excitation in predisposed patients.

Levofloxacine Arrow requires careful consideration of patient‑specific factors before use.

• Renal function: assess creatinine clearance and adjust therapy in renal impairment.
• QT interval: avoid in patients with known QT prolongation or concurrent QT‑prolonging drugs.
• Concomitant NSAIDs: monitor for increased risk of central nervous system effects.
• Allergy: discontinue immediately if signs of hypersensitivity appear.
• Pregnancy: use only if the potential benefit justifies the potential risk to the fetus (category unknown).
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Levofloxacine Arrow can interact with several medicines, requiring vigilance.

Major Interactions (Avoid)

• Co‑administration with other fluoroquinolones: additive toxicity.
• Concurrent QT‑prolonging agents (e.g., macrolides, antiarrhythmics): heightened risk of arrhythmia.
• Antacids containing aluminum or magnesium: reduce levofloxacin absorption.
• Warfarin: may increase INR and bleeding risk.

Moderate Interactions (Monitor Closely)

• Corticosteroids: increased risk of tendon rupture.
• Theophylline: levofloxacin may raise serum theophylline levels.
• Cyclosporine: possible elevation of cyclosporine concentrations.
