What is Norfloxacin?
Norfloxacin, the active ingredient in Norfloxacina Sandoz, is a fluoroquinolone antibiotic presented as an oral dosage form for oral use. It treats a range of bacterial infections, particularly in the urinary and genitourinary tracts, and is prescribed for adults and selected pediatric patients. The drug exerts its antibacterial effect by inhibiting key enzymes involved in bacterial DNA replication, leading to bactericidal activity against susceptible Gram‑negative and some Gram‑positive organisms.
GNH USA supplies Norfloxacina Sandoz as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.
What is Norfloxacin used for?
Norfloxacina Sandoz, a fluoroquinolone antibiotic, is indicated for several bacterial infections affecting the urinary and genitourinary systems.
- Urinary tract infections: eradicates susceptible bacteria causing uncomplicated cystitis and pyelonephritis. - Acute prostatitis: achieves bacterial clearance in inflammation of the prostate gland. - Uncomplicated gonorrhea: provides effective therapy against Neisseria gonorrhoeae strains. - Traveler's diarrhea: reduces duration and severity of bacterial diarrheal illness acquired abroad.
What are the side effects of Norfloxacin?
Norfloxacina Sandoz may cause a range of adverse reactions, which are classified by frequency and severity.
Common Side Effects: - Nausea: mild stomach upset often reported. - Diarrhea: loose stools occurring during treatment. - Headache: transient cranial discomfort. - Dizziness: sensation of light‑headedness. - Abdominal pain: cramping or discomfort in the stomach area. - Rash: mild skin erythema or itching.
Serious or Rare Side Effects: - Tendon rupture: risk of Achilles or other tendon tears. - QT interval prolongation: potential cardiac arrhythmia. - Severe allergic reactions: including Stevens‑Johnson syndrome or anaphylaxis.
What precautions apply to Norfloxacin?
When prescribing Norfloxacina Sandoz, clinicians should observe several precautionary measures to minimise risks.
- Assess renal function: dose adjustment may be required in impaired clearance. - Avoid in patients with known hypersensitivity to fluoroquinolones. - Monitor for tendon pain: discontinue if signs of tendonitis appear. - Caution in patients with cardiac arrhythmias: evaluate QT interval before use. - Store at ambient temperature below 25°C: keep in original container, protect from moisture and light.
What does Norfloxacin interact with?
Norfloxacina Sandoz can interact with other medicines, altering its efficacy or safety profile.
Major Interactions (Avoid): - Antacids containing aluminum or magnesium: reduce absorption of norfloxacin. - Warfarin: may increase anticoagulant effect and bleeding risk.
Moderate Interactions (Monitor Closely): - NSAIDs (e.g., ibuprofen): may increase risk of central nervous system stimulation. - Theophylline: potential for increased serum levels and toxicity. - Corticosteroids: combined use may raise risk of tendon rupture.
