Itorex (Cefuroxime Sodium)

Cefuroxime sodium is a broad‑spectrum cephalosporin antibiotic used to treat infections of the respiratory, urinary, and skin systems.

• Community‑acquired pneumonia: eliminates causative bacteria and improves respiratory symptoms.
• Upper and lower respiratory tract infections: reduces bacterial load and accelerates recovery.
• Urinary tract infections: eradicates common uropathogens and relieves urinary symptoms.
• Skin and soft‑tissue infections: clears bacterial invasion of skin layers.
• Acute otitis media: resolves middle‑ear infection and associated pain.
• Sinusitis: treats bacterial sinus inflammation and restores normal drainage.

• Cefuroxime sodium inhibits bacterial cell‑wall synthesis by binding to penicillin‑binding proteins (PBPs) located on the inner surface of the bacterial membrane. This binding interferes with the cross‑linking of peptidoglycan strands, weakening the cell wall and leading to osmotic instability and bacterial lysis, particularly against Gram‑positive and some Gram‑negative organisms.

Cefuroxime sodium may cause a range of adverse reactions, most of which are mild and self‑limiting.

Common Side Effects

• Injection site pain: mild discomfort at the intramuscular site.
• Diarrhoea: loose stools occurring during therapy.
• Nausea: feeling of queasiness without vomiting.
• Vomiting: expulsion of stomach contents.
• Rash: mild skin redness or itching.
• Transient elevation of liver enzymes: temporary increase in hepatic markers.

Serious or Rare Side Effects

• Anaphylaxis: severe allergic reaction with breathing difficulty.
• Clostridioides difficile‑associated diarrhoea: severe colitis after antibiotic use.
• Stevens‑Johnson syndrome: rare, life‑threatening skin reaction.
• Hemolytic anemia: destruction of red blood cells.
• Thrombocytopenia: low platelet count increasing bleeding risk.
• Acute renal impairment: sudden decrease in kidney function.

Before using Itorex, clinicians should consider several safety measures.

• Assess allergy: verify no known hypersensitivity to cephalosporins or penicillins.
• Evaluate renal function: adjust dose in patients with impaired kidney function.
• Monitor hepatic enzymes: watch for significant liver enzyme elevations.
• Caution in pregnancy: use only if the potential benefit outweighs risk.
• Observe for superinfection: discontinue if signs of secondary infection appear.
• Store at 2‑8 °C: keep refrigerated, protect from light, do not freeze or shake.

Cefuroxime sodium can interact with other medicines, requiring attention to avoid reduced efficacy or increased toxicity.

Major Interactions (Avoid)

• Probenecid: may increase cefuroxime plasma levels and risk toxicity.
• Live bacterial vaccines: antibiotic may diminish vaccine effectiveness.
• Warfarin: potential enhancement of anticoagulant effect leading to bleeding.

Moderate Interactions (Monitor Closely)

• Aminoglycosides: additive nephrotoxic potential; monitor renal function.
• Loop diuretics: may increase risk of renal impairment.
• Oral contraceptives: possible reduction in contraceptive efficacy; advise alternative protection.
