Dosage & Route
- PO Uncomplicated UTI 125 mg twice daily. Respiratory tract infections 250-500 mg twice daily. Uncomplicated gonorrhea W/ oral probenecid: 1 g as a single dose. IV Meningitis 3 g 8 hrly. IM Gonorrhea W/ oral probenecid: 1.5 g as a single dose. IV/IM Surgical prophylaxis 1.5 g IV per-op, then 750 mg IM 8 hrly for up to 24-48 hr. Susceptible infections750 mg 8 hrly, up to 1.5 g 6-8 hrly for severe infections.
Therapeutic actions
- Cefuroxime binds to one or more of the penicillin-binding proteins (PBPs) which inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell wall, thus inhibiting biosynthesis and arresting cell wall assembly resulting in bacterial cell death.
- Absorption: Absorbed from the GI tract with peak plasma concentrations after 2-3 hr (oral); may be enhanced by the presence of food.
- Distribution: Pleural and synovial fluid, sputum, bone and aqueous fluids; CSF (therapeutic concentrations). Crosses the placenta and enters breast milk. Protein-binding: Up to 50%.
- Metabolism: Rapidly hydrolysed (intestinal mucosa and blood).
- Excretion: Via the urine by glomerular filtration and renal tubular secretion (as unchanged); via bile (small amounts); 70 min (elimination half-life); prolonged in neonates and renal impairment.

- Potentially Fatal: Anaphylaxis, nephrotoxicity, pseudomembranous colitis.
Contraindications

Nursing considerations
Assessment
- History: Hepatic and renal impairment, lactation, pregnancy
- Physical: Skin status, LFTs, renal function tests, culture of affected area, sensitivity tests
Interventions
- Culture infection, and arrange for sensitivity tests before and during therapy if expected response is not seen.
- Give oral drug with food to decrease GI upset and enhance absorption.
- Give oral drug to children who can swallow tablets; crushing the drug results in a bitter, unpleasant taste.
- Have vitamin K available in case hypoprothrombinemia occurs.
- Discontinue if hypersensitivity reaction occurs.
