Levofloxacino Stada (Levofloxacin)

Levofloxacin is a fluoroquinolone antibiotic used to treat bacterial infections in various organ systems.

• Community‑acquired pneumonia: effective in eliminating the causative bacteria and improving respiratory symptoms.
• Acute bacterial sinusitis: reduces sinus inflammation by eradicating the infecting organisms.
• Uncomplicated urinary tract infection: clears the infection and relieves urinary discomfort.
• Complicated urinary tract infection: provides bactericidal activity against resistant uropathogens.
• Acute bacterial skin and skin structure infections: resolves cellulitis, abscesses, and wound infections.
• Chronic prostatitis: penetrates prostatic tissue to treat persistent bacterial prostatitis.

• Levofloxacin exerts its antibacterial activity by binding to the bacterial enzymes DNA gyrase (topoisomerase II) and topoisomerase IV. Inhibition of these enzymes prevents the supercoiling and separation of DNA strands required for replication and transcription, leading to bacterial cell death. The drug displays concentration‑dependent killing against a broad spectrum of Gram‑negative and Gram‑positive organisms.

Levofloxacin may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects

• Nausea: mild gastrointestinal upset that usually resolves without intervention.
• Diarrhea: loose stools that may be self‑limiting.
• Headache: transient cranial discomfort.
• Dizziness: occasional sense of light‑headedness.
• Rash: mild skin erythema or pruritus.
• Insomnia: difficulty falling or staying asleep.

Serious or Rare Side Effects

• Tendon rupture: sudden pain and loss of function, especially in the Achilles tendon.
• QT interval prolongation: risk of cardiac arrhythmias.
• Peripheral neuropathy: numbness or tingling in extremities.
• Clostridioides difficile infection: severe colitis following disruption of gut flora.
• Anaphylaxis: life‑threatening allergic reaction requiring immediate medical attention.
• Hepatic dysfunction: elevated liver enzymes or jaundice.

When prescribing levofloxacin, clinicians should consider several safety factors.

• Renal impairment: adjust therapy based on renal function and monitor kidney parameters.
• History of tendon disorders: avoid use or discontinue promptly if tendon pain or swelling occurs.
• Cardiac risk: caution in patients with QT prolongation or other arrhythmias.
• Pregnancy and lactation: use only if benefits outweigh potential risks; safety data are limited.
• Drug interactions: review concomitant medications for potential interactions.
• Store at ambient temperature: keep below 25 °C, in the original packaging, protected from moisture and light.

Levofloxacin can interact with several medicines, requiring careful management.

Major Interactions (Avoid)

• Antacids containing magnesium or aluminum: reduce levofloxacin absorption.
• Warfarin: may increase anticoagulant effect and bleeding risk.
• Theophylline: heightened risk of toxicity.

Moderate Interactions (Monitor Closely)

• NSAIDs: may increase risk of central nervous system stimulation.
• Corticosteroids: elevated chance of tendon injury.
