Ofloxacine Evolugen (Ofloxacin)

Ofloxacine Evolugen (ofloxacin) is a fluoroquinolone antibiotic used to treat bacterial infections in various organ systems.

• Urinary tract infection: eradicates susceptible uropathogens, relieving symptoms and preventing recurrence.
• Respiratory tract infection: targets common respiratory bacteria, improving cough, sputum and fever.
• Skin and soft tissue infection: combats Gram‑negative and Gram‑positive organisms in cellulitis and wound infections.
• Prostatitis: penetrates prostatic tissue to treat chronic bacterial prostatitis.
• Gonorrhea: effective against Neisseria gonorrhoeae strains susceptible to fluoroquinolones.

• Ofloxacin exerts its antibacterial effect by binding to bacterial DNA gyrase (topoisomerase II) and topoisomerase IV. Inhibition of these enzymes prevents the supercoiling and resealing of DNA during replication and transcription, leading to interruption of bacterial DNA synthesis and cell death. This mechanism underlies its efficacy in urinary, respiratory, skin and soft‑tissue, and genitourinary infections.

Like all fluoroquinolones, ofloxacin may cause adverse reactions that vary in frequency and severity.

Common Side Effects

• Nausea: mild stomach upset that usually resolves without treatment.
• Diarrhea: loose stools that are typically transient.
• Headache: dull to moderate headache, often relieved by simple analgesics.
• Dizziness: occasional light‑headedness or vertigo, generally short‑lived.
• Rash: mild skin redness or itching that improves after stopping the drug.

Serious or Rare Side Effects

• Tendon rupture: possible tear of Achilles or other tendons, especially in older patients.
• QT prolongation: lengthening of cardiac repolarisation that may lead to arrhythmia.
• Severe allergic reaction: anaphylaxis with hives, swelling and breathing difficulty.
• Central nervous system effects: seizures, confusion or psychosis in susceptible individuals.

When prescribing Ofloxacine Evolugen, clinicians should observe several precautionary measures to minimise risks.

• Renal impairment: assess kidney function and consider dose adjustment or alternative therapy.
• Hepatic disease: exercise caution in patients with moderate to severe liver dysfunction.
• Concomitant QT‑prolonging drugs: avoid combination or monitor ECG for arrhythmia.
• History of tendon disorders: contraindicated in patients with previous tendon injury or inflammation.
• Pregnancy and lactation: prescribe only when clearly needed, as safety data are limited.
• Store at ambient temperature: keep below 25 °C 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: reduce absorption of ofloxacin.
• Fluoroquinolone‑specific chelators (e.g., iron supplements): markedly decrease oral bioavailability.
• NSAIDs (e.g., ibuprofen, diclofenac): increase risk of central nervous system stimulation and seizures.
• Cyclosporine: may raise ofloxacin serum levels leading to toxicity.

Moderate Interactions (Monitor Closely)

• Warfarin: may enhance anticoagulant effect, requiring INR monitoring.
• Theophylline: ofloxacin can increase plasma theophylline concentrations.
• Corticosteroids: combined use may raise risk of tendon rupture.
• Diabetic agents (e.g., insulin, sulfonylureas): possible hypoglycaemia, monitor blood glucose.
