1. Pharmacology

Cefuroxime Axetil is a cephalosporin antibiotic that works by inhibiting the synthesis of bacterial cell walls. The active form, cefuroxime, binds to penicillin-binding proteins, disrupting cell wall synthesis and leading to bacterial lysis.

2. Indication

Cefuroxime Axetil is used for treating a variety of bacterial infections, including:

  • Upper and lower respiratory tract infections (e.g., otitis media, pharyngitis, bronchitis, pneumonia).

  • Urinary tract infections.

  • Skin and soft tissue infections.

  • Lyme disease (early stages).

  • Gonorrhea.

  • Sinusitis.

3. Dosage & Administration

  • Adults:

    • For mild to moderate infections: 250 mg to 500 mg twice daily.

    • For severe infections: 500 mg to 1,000 mg twice daily.

  • Children: The dosage depends on age and weight, typically 20 mg/kg/day in divided doses.

Cefuroxime Axetil should be taken with food to enhance absorption.

4. Interaction

Cefuroxime Axetil may interact with:

  • Probenecid: May increase cefuroxime levels by reducing renal excretion.

  • Anticoagulants: Increased bleeding risk when used together.

  • Oral contraceptives: Potential reduced effectiveness of birth control.

5. Contraindications

  • Hypersensitivity to cephalosporins or penicillins.

  • History of severe allergic reactions to beta-lactam antibiotics.

6. Side Effects

Common side effects include:

  • Gastrointestinal disturbances (e.g., diarrhea, nausea).

  • Allergic reactions (e.g., rash, urticaria).

  • Headache.

  • Dizziness.

  • Elevated liver enzymes.

  • Rarely, severe reactions like anaphylaxis or Stevens-Johnson syndrome.

7. Pregnancy & Lactation

  • Pregnancy: Category B (no evidence of harm in animal studies, but should be used when clearly needed).

  • Lactation: Cefuroxime is excreted in breast milk in low concentrations. It should be used with caution during breastfeeding, considering the potential risk of side effects to the infant.

8. Precautions & Warnings

  • Renal impairment: Dose adjustments may be required in patients with impaired renal function.

  • Diarrhea: Should be used with caution in patients with a history of gastrointestinal disease.

  • Superinfection: Prolonged use may lead to the overgrowth of non-susceptible organisms.

9. Overdose Effects

Symptoms of overdose may include:

  • Gastrointestinal disturbances (e.g., nausea, vomiting).

  • Central nervous system effects (e.g., seizures, confusion).

  • Acute renal failure in severe cases.

Treatment involves supportive care, including hydration and monitoring.

10. Therapeutic Class

  • Antibiotic: Second-generation cephalosporin.

11. Storage Conditions

  • Store at room temperature, away from moisture and heat.

  • Do not freeze.

  • Keep the medication in its original packaging to protect it from light.

12. Chemical Structure

Cefuroxime Axetil is a prodrug of cefuroxime. The chemical structure consists of:

  • A beta-lactam ring (responsible for its antibacterial activity).

  • A cephalosporin nucleus with an acetoxyethyl side chain (which is cleaved after absorption to release the active cefuroxime).

The chemical formula of cefuroxime axetil is C20H22N6O10S3.
