Drug Overview

Drug Name

• Generic Name: Cefuroxime
• Brand Names: Ceftin (oral), Zinacef (parenteral)

Classification

Cefuroxime is classified as a second-generation cephalosporin antibiotic.

Mechanism of Action

Cefuroxime is bactericidal, inhibiting bacterial cell wall synthesis by binding to penicillin-binding proteins. This disrupts peptidoglycan cross-linking, weakening the cell wall and causing bacterial lysis. It is effective against gram-positive bacteria (e.g., Streptococcus pneumoniae, Staphylococcus aureus) and gram-negative bacteria (e.g., Haemophilus influenzae, Escherichia coli, Klebsiella pneumoniae), with improved activity against beta-lactamase-producing strains compared to first-generation cephalosporins.

Indications

Cefuroxime is indicated for:

• Respiratory Tract Infections: Pharyngitis, tonsillitis, sinusitis, bronchitis, and community-acquired pneumonia caused by susceptible pathogens (e.g., S. pneumoniae, H. influenzae).
• Otitis Media: In children and adults, caused by S. pneumoniae, H. influenzae, or Moraxella catarrhalis.
• Skin and Skin Structure Infections: Caused by S. aureus or Streptococcus pyogenes.
• Urinary Tract Infections (UTIs): Caused by E. coli or Klebsiella pneumoniae.
• Bone and Joint Infections: Caused by S. aureus (parenteral).
• Gonorrhea: Uncomplicated cases caused by Neisseria gonorrhoeae.
• Lyme Disease: Early-stage disease caused by Borrelia burgdorferi (oral).
• Perioperative Prophylaxis: To prevent surgical site infections (parenteral).
• Meningitis or Sepsis: In select cases caused by susceptible pathogens (parenteral, under specialist guidance).

Note: Ineffective against viral infections or atypical bacteria (e.g., Mycoplasma, Chlamydia).

Dosage & Route

• Adults:
  • Oral (Ceftin):
    • Respiratory infections, skin infections: 250–500 mg every 12 hours for 7–10 days.
    • UTIs: 250 mg every 12 hours for 7–10 days.
    • Lyme disease: 500 mg every 12 hours for 14–21 days.
    • Gonorrhea: 1 g single dose.
  • Parenteral (Zinacef):
    • Mild to moderate infections: 750 mg IV/IM every 8 hours.
    • Severe infections (e.g., pneumonia, bone infections): 1.5 g IV every 8 hours.
    • Surgical prophylaxis: 1.5 g IV single dose preoperatively, may repeat every 8 hours for 24 hours.

    • Severe infections (e.g., meningitis): 100–150 mg/kg/day IV in 3 divided doses (maximum 6 g/day).
• Geriatrics: No dose adjustment needed unless renal impairment is present.
• Renal Impairment:
  • Creatinine clearance 10–30 mL/min: Standard dose every 12–24 hours (oral or parenteral).
  • Creatinine clearance <10 mL/min: Standard dose every 24–48 hours.
• Route: Oral (tablets: 250 mg, 500 mg; suspension: 125 mg/5 mL, 250 mg/5 mL); Intravenous (IV); Intramuscular (IM).

Administration Notes:

• Oral: Take with food to enhance absorption and reduce gastrointestinal upset. Shake suspension well; measure with a calibrated device. Store suspension in refrigerator; discard after 10 days.
• Parenteral: Administer IV over 3–5 minutes (direct) or 15–30 minutes (infusion). For IM, inject into large muscle (e.g., gluteus); reconstitute per manufacturer instructions.
• Rotate IM injection sites to prevent tissue damage.

Nursing Considerations

Assessment

• Baseline Evaluation:
  • Assess for signs of infection (e.g., fever, purulent discharge, pain, dysuria).
  • Obtain culture and sensitivity results (if available) to confirm susceptibility.
  • Check renal function (serum creatinine), liver function, and allergy history, especially to penicillins or cephalosporins.
• Medical History: Screen for gastrointestinal disorders (e.g., colitis), bleeding disorders, or history of hypersensitivity reactions.
• Allergy History: Approximately 10% of penicillin-allergic patients may react to cephalosporins; confirm no severe reactions (e.g., anaphylaxis).
• Medication Review: Identify concurrent use of drugs affecting renal function or gut flora.

Interventions

• Administration:
  • Oral: Administer with food; ensure accurate pediatric dosing using weight-based calculations.
  • Parenteral: Use aseptic technique; verify IV compatibility and patency. For IM, aspirate to avoid vascular injection.
  • Ensure timely administration to maintain therapeutic levels, especially for severe infections.
• Monitoring:
  • Monitor for resolution of infection symptoms (e.g., reduced fever, improved respiratory status).
  • Assess for adverse effects, particularly diarrhea, rash, or signs of hypersensitivity.
  • Monitor renal and hepatic function in prolonged therapy or renal impairment.
  • Observe for signs of superinfection (e.g., oral thrush, vaginal candidiasis) with extended use.
  • For IV/IM, inspect injection sites for redness, swelling, or phlebitis.
• Safety Measures:
  • Educate on completing the full course to prevent antibiotic resistance.
  • Ensure emergency equipment is available for anaphylactic reactions.
  • Store medication securely to prevent accidental ingestion by children.

Teaching Points

• Medication Use:
  • “Take cefuroxime as prescribed, even if you feel better, to fully treat the infection.”
  • “For the liquid, shake it well, measure with the provided device, and keep it in the fridge.”
• Side Effects:
  • “You might have diarrhea or a rash. Tell us if it’s severe or you notice swelling or breathing problems.”
• Lifestyle:
  • “Take oral doses with food to help with stomach upset.”
  • “Avoid alcohol, as it may worsen stomach upset.”
• When to Seek Help:
  • “Go to the ER if you have severe diarrhea with blood, trouble breathing, or swelling.”
  • “Call your doctor if symptoms don’t improve after a few days or you get a new fever.”

Adverse Effects

Cefuroxime is generally well-tolerated, but adverse effects can occur, primarily affecting the gastrointestinal system.

Common Adverse Effects

• Diarrhea
• Nausea
• Vomiting
• Abdominal pain
• Rash
• Injection site reactions (pain, redness for IM/IV)

Serious Adverse Effects

• Hypersensitivity Reactions: Anaphylaxis, angioedema, or Stevens-Johnson syndrome (rare).
• Clostridium difficile-Associated Diarrhea (CDAD): Ranges from mild to life-threatening colitis; monitor for bloody or persistent diarrhea.
• Hematologic: Eosinophilia, leukopenia, thrombocytopenia, or hemolytic anemia (rare).
• Hepatic: Elevated liver enzymes or hepatitis (rare); monitor in prolonged use.
• Renal: Acute kidney injury (rare); monitor in renal impairment.
• Neurologic: Seizures (rare, typically in renal impairment with high doses).

Overdose: Symptoms include seizures, encephalopathy, or renal impairment. Treat with supportive care; hemodialysis may be effective due to renal excretion.

Contraindications

• Absolute:
  • Hypersensitivity to cefuroxime, other cephalosporins, or formulation components.
• Relative:
  • History of penicillin allergy (assess severity; avoid if anaphylaxis history).
  • History of C. difficile colitis or severe gastrointestinal disease.

Precautions

• Pregnancy (Category B): No evidence of fetal harm in animal studies; human data support safety. Use if benefits outweigh risks.
• Lactation: Minimal excretion in breast milk; considered safe, but monitor infants for diarrhea or rash.
• Pediatrics: Safe for infants ≥1 month (parenteral) or ≥3 months (oral); ensure accurate dosing.
• Geriatrics: No specific adjustments unless renal impairment; monitor for adverse effects.
• Renal Impairment: Adjust dose based on creatinine clearance to prevent accumulation and toxicity.

Drug Interactions

• Probenecid: Increases cefuroxime levels by reducing renal excretion; monitor for toxicity.
• Aminoglycosides: Potential for additive nephrotoxicity; monitor renal function.
• Oral Contraceptives: Antibiotics may reduce efficacy; advise backup contraception during therapy.
• Antacids or H2-Receptor Antagonists: May reduce oral absorption; separate doses by 1–2 hours.
• Live Bacterial Vaccines (e.g., typhoid): Antibiotics may reduce vaccine efficacy; time vaccination appropriately.

Nurses should review medication lists and educate patients on timing doses to avoid interactions.

Pharmacokinetics

• Absorption:
  • Oral: ~37–52% bioavailability; enhanced with food.
  • Parenteral: 100% bioavailability (IM/IV).
• Distribution: Widely distributed; 33–50% protein-bound; penetrates bone, joint, and cerebrospinal fluid (with inflamed meninges).
• Metabolism: Minimal hepatic metabolism.
• Excretion: Primarily renal (66–100% unchanged); half-life ~1–2 hours (prolonged in renal impairment).
• Onset of Action: Within hours; clinical improvement may take 2–3 days.
• Peak Effect: 2–3 hours (oral); 15–60 minutes (IV/IM).

This profile supports flexible dosing (oral or parenteral) and highlights the need for renal dose adjustments.

Special Considerations

Pregnancy

• Safe for use if indicated; widely used in pregnancy for UTIs or other infections.

Pediatrics

• Ensure accurate dosing using weight-based calculations.
• Educate caregivers on suspension storage (refrigerate) and administration.
• Monitor for diaper rash or thrush with prolonged use.

Geriatrics

• Monitor for gastrointestinal side effects and renal function.
• Simplify regimens to enhance adherence.

Renal Impairment

• Adjust dose based on creatinine clearance to prevent toxicity.
• Monitor for seizures or other neurologic effects in severe impairment.

Patient Case Example

A 10-year-old child (30 kg) with acute sinusitis is prescribed cefuroxime 15 mg/kg every 12 hours (450 mg/dose, 9 mL of 125 mg/5 mL suspension) for 10 days. The nurse confirms no penicillin allergy, educates the caregiver on refrigerating the suspension and taking it with food, and advises monitoring for diarrhea. After 5 days, the child’s sinus symptoms improve, but a mild rash appears. The nurse assesses for hypersensitivity, advises monitoring, and consults the prescriber for potential continuation or alternative therapy.

Conclusion

Cefuroxime is a versatile second-generation cephalosporin effective for a range of bacterial infections, offering both oral and parenteral options. Nurses ensure its safe use through thorough assessments, precise administration, vigilant monitoring, and comprehensive patient education. By addressing cefuroxime nursing considerations, nurses enhance patient safety, promote adherence, and prevent complications like antibiotic resistance or superinfections, tailoring care to individual needs for optimal outcomes.
