Ofloxacin Unimed Pharma (Ofloxacin)

Ofloxacin is a fluoroquinolone antibiotic used to treat bacterial infections affecting various organ systems.

• Urinary tract infection: eradicates susceptible Gram‑negative and Gram‑positive pathogens, relieving symptoms and preventing complications.
• Acute bacterial sinusitis: reduces bacterial load and improves sinus drainage in adults.
• Skin and soft‑tissue infection: clears susceptible Staphylococcus and Streptococcus species, promoting wound healing.
• Community‑acquired pneumonia: targets common respiratory pathogens, aiding recovery.

• Ofloxacin exerts its antibacterial effect by inhibiting bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, enzymes essential for DNA replication, transcription, and repair. By binding to the enzyme‑DNA complex, it prevents the resealing of DNA strands, leading to accumulation of double‑strand breaks and bacterial cell death. The dual targeting of gyrase and topoisomerase IV broadens its activity against Gram‑negative and Gram‑positive organisms.

Like other fluoroquinolones, Ofloxacin may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects

• Nausea: mild gastrointestinal upset.
• Diarrhea: loose stools, often self‑limiting.
• Headache: transient cranial discomfort.
• Dizziness: occasional vertigo or light‑headedness.
• Rash: mild skin erythema or itching.

Serious or Rare Side Effects

• Tendon rupture: especially Achilles, requiring immediate medical attention.
• QT interval prolongation: may predispose to cardiac arrhythmias.
• Severe allergic reaction: anaphylaxis or angioedema.
• Clostridioides difficile colitis: severe diarrhea due to gut flora disruption.

Appropriate use of Ofloxacin requires careful assessment of patient risk factors and clinical conditions.

• Hypersensitivity: avoid in patients with known allergy to fluoroquinolones or related compounds.
• Tendon disorders: discontinue if tendon pain, swelling, or inflammation occurs.
• Cardiac risk: caution in patients with known QT prolongation or electrolyte imbalance.
• Pregnancy and lactation: use only if clearly needed, as safety data are limited.
• Renal/hepatic impairment: dose adjustment may be required; monitor function.
• Pediatric use: reserve for specific indications and weight‑based dosing under supervision.
• Store at ambient temperature: keep below 25 °C, retain in original packaging, protect from moisture.

Ofloxacin can interact with several medicines, altering its efficacy or increasing toxicity.

Major Interactions (Avoid)

• Antacids containing aluminum or magnesium: chelate Ofloxacin, reducing absorption.
• Sucralfate: binds the drug and markedly decreases bioavailability.
• Warfarin: may enhance anticoagulant effect, increasing bleeding risk.
• Corticosteroids: combined use raises risk of tendon rupture.
• Theophylline: Ofloxacin can increase plasma levels, leading to toxicity.

Moderate Interactions (Monitor Closely)

• Non‑steroidal anti‑inflammatory drugs (NSAIDs): may increase risk of CNS stimulation.
• Diabetes medications (e.g., insulin, sulfonylureas): Ofloxacin may affect glucose control.
• Cyclosporine: potential for increased serum concentrations.
• Oral contraceptives: may reduce effectiveness; advise additional contraception.
