Ofloxacine Eg (Ofloxacin)

Ofloxacin is indicated for infections caused by susceptible bacteria affecting various organ systems.

• Urinary tract infection: eradicates susceptible uropathogens and resolves dysuria and frequency.
• Acute bacterial sinusitis: eliminates causative organisms and improves nasal congestion.
• Community‑acquired lower respiratory tract infection: clears pathogens responsible for bronchitis and pneumonia.
• Skin and soft‑tissue infection: treats cellulitis and wound infections caused by susceptible strains.
• Gonorrhea (uncomplicated): provides bactericidal activity against Neisseria gonorrhoeae.

• Ofloxacin inhibits bacterial DNA gyrase and topoisomerase IV, enzymes essential for DNA replication, transcription, and repair. By binding to these enzymes, it prevents the supercoiling and relaxation of DNA, leading to interruption of bacterial cell division and ultimately bacterial cell death. The drug exhibits concentration‑dependent bactericidal activity against a broad spectrum of Gram‑negative and some Gram‑positive organisms.

Adverse reactions to Ofloxacin can range from mild to severe and may vary with patient factors.

Common Side Effects

• Nausea: mild to moderate gastrointestinal upset.
• Diarrhea: loose stools, occasionally watery.
• Headache: transient cranial discomfort.
• Dizziness: sensation of light‑headedness.
• Abdominal pain: cramp‑like discomfort.
• Rash: mild skin erythema.

Serious or Rare Side Effects

• Tendon rupture: sudden tendon pain or rupture, especially Achilles.
• QT interval prolongation: risk of cardiac arrhythmias.
• Severe allergic reactions: anaphylaxis, Stevens‑Johnson syndrome.
• Clostridioides difficile‑associated diarrhea: severe colitis.
• Hepatic dysfunction: elevated liver enzymes, jaundice.
• Peripheral neuropathy: tingling or numbness in extremities.

Before prescribing Ofloxacin, clinicians should consider several safety aspects.

• Renal impairment: dose adjustment may be required in reduced kidney function.
• History of tendon disorders: avoid use in patients with prior tendon injury.
• QT prolongation risk: monitor ECG in patients with cardiac arrhythmia history.
• Pregnancy and lactation: reserve for situations where benefits outweigh potential risks.
• Concomitant medications: review for interactions that may increase toxicity.
• Store at ambient temperature: keep in original packaging, protect from moisture and direct sunlight.

Ofloxacin may interact with other medicines, altering efficacy or safety.

Major Interactions (Avoid)

• Antacids containing aluminum or magnesium: reduce Ofloxacin absorption.
• NSAIDs (e.g., ibuprofen): increase risk of central nervous system adverse effects.
• Systemic corticosteroids: heighten risk of tendon rupture.
• Other fluoroquinolones (e.g., ciprofloxacin): additive QT prolongation.
• Warfarin: may enhance anticoagulant effect and increase bleeding risk.

Moderate Interactions (Monitor Closely)

• Theophylline: Ofloxacin can raise plasma theophylline concentrations.
• Cyclosporine: increased cyclosporine levels may occur.
• Diabetes medications (e.g., insulin): possible alteration of glucose control.
