Levofloxacin Crescent Pharma (Levofloxacin Hemihydrate)

Levofloxacin is a fluoroquinolone antibacterial that targets a broad spectrum of bacterial pathogens in various infection sites.

• Community‑acquired respiratory tract infection: resolves infection caused by susceptible organisms and improves respiratory symptoms.
• Acute bacterial sinusitis: eradicates the causative bacteria and relieves sinus congestion.
• Acute bacterial exacerbation of chronic bronchitis: reduces bacterial load and helps restore lung function.
• Uncomplicated urinary tract infection: eliminates the infecting pathogen and alleviates urinary symptoms.
• Complicated urinary tract infection: provides bactericidal activity against resistant strains in the urinary system.
• Skin and soft‑tissue infection: treats bacterial cellulitis, abscesses and other soft‑tissue infections.

• Levofloxacin inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, enzymes essential for DNA replication, transcription and repair. By binding to these enzymes, it prevents the supercoiling and separation of DNA strands, leading to bacterial cell death. The drug exhibits concentration‑dependent bactericidal activity against a wide range of Gram‑positive and Gram‑negative organisms.

Levofloxacin may cause adverse reactions ranging from mild to severe.

Common Side Effects

• Nausea: mild to moderate upset stomach.
• Diarrhea: loose stools that may be self‑limiting.
• Headache: transient cranial discomfort.

Serious or Rare Side Effects

• Tendon rupture: especially Achilles tendon, may occur during or after therapy.
• QT interval prolongation: can precipitate cardiac arrhythmias.
• Severe allergic reactions: including anaphylaxis and angioedema.

When prescribing Levofloxacin, several safety considerations should be evaluated.

• Renal impairment: dose adjustment may be required based on renal function.
• History of tendon disorders: avoid use due to risk of tendon rupture.
• QT interval prolongation: monitor ECG in patients with cardiac risk factors.
• Pregnancy and lactation: use only if benefits outweigh potential risks.
• Concomitant medications: review for possible drug interactions.
• Store at ambient temperature: keep in original container, protect from moisture and light.

Levofloxacin can interact with other medicines, affecting its efficacy or safety.

Major Interactions (Avoid)

• Antacids containing aluminum or magnesium: reduce levofloxacin absorption.
• Warfarin: may increase anticoagulant effect and bleeding risk.
• Theophylline: can raise serum theophylline concentrations.
• Cyclosporine: may increase cyclosporine levels and nephrotoxicity.

Moderate Interactions (Monitor Closely)

• NSAIDs: may enhance central nervous system stimulation.
• Corticosteroids: combined use increases risk of tendon rupture.
• Diabetic agents: may potentiate hypoglycemia.
