Cefuroxime is a bactericidal second-generation cephalosporin antibiotic that kills a wide spectrum of Gram-positive & negative bacteria, including many beta-lactamase-producing strains. Cefuroxime works by interfering with the transpeptidation process, which stops bacteria from making cell walls. Streptomyces clavuligerus produces clavulanic acid, a naturally derived beta-lactamase inhibitor. It has a structure comparable to beta-lactam antibiotics, and it binds to beta-lactamase enzymes and inactivates them irreversibly. Clavulanic acid protects Cefuroxime against breakdown by beta-lactamase enzymes, making it a viable therapy option for bacterial infections.

Pharmacology:
Cefuroxime is a bactericidal second generation cephalosporin antibiotic which is active against a wide range of Gram-positive and Gram-negative susceptible organisms including many beta-lactamase producing strains. Cefuroxime inhibits bacterial cell wall synthesis by interfering with the transpeptidation process. Clavulanic acid is a naturally derived beta lactamase inhibitor produced by Streptomyces clavuligerus. It has similar structure to beta lactam antibiotics which binds irreversibly to beta-lactamase enzymes and inactivates them. Clavulanic acid gives protection of Cefuroxime from degradation by beta lactamase enzymes and provides a solution for the treatment of bacterial infections caused by beta lactam resistant bacteria.

Route of administration: Orally.Interaction: Concomitant administration of probenecid with Cefuroxime-Clavulanic Acid increases the area under the serum concentration versus time curve by 50%. Drug that reduces gastric acidity may result in a lower bioavailability of Cefuroxime and tend to cancel the effect of postprandial absorption. Contraindications:Cefuroxime-Clavulanic Acid is contraindicated in patients with known allergy to cephalosporin & in patients with Pseudomembranous Colitis. Side Effects: Generally Cefuroxime-Clavulanic Acid is well tolerated. However, a few side effects like nausea, vomiting, diarrhea, abdominal discomfort or pain may occur. As with other broad-spectrum antibiotics, prolonged administration of Cefuroxime and Clavulanic acid combination may result in overgrowth of nonsusceptible microorganisms. Rarely (<0.2%) renal dysfunction, anaphylaxis, angioedema, pruritis, rash and serum sickness like urticaria may appear.  Pregnancy & Lactation: While all antibiotics should be avoided in the first trimester if possible. However, Cefuroxime-Clavulanic Acid can be safely used in later pregnancy to treat urinary and other infections. Cefuroxime-Clavulanic Acid is excreted into the breast milk in small quantities. However, the possibility of sensitizing the infant should be kept in mind.  Precautions & Warnings: Cefuroxime should be given with care to patients receiving concurrent treatment with potent diuretics & who has history of colitis.  Therapeutic Class:Second generation Cephalosporins Storage Conditions: Store in a cool, dry place (below 30o C), away from light and moisture. Keep out of the reach of children.
