Furoclav 500 mg Tablet is a combination antibiotic containing Cefuroxime Axetil (500 mg) and Clavulanic Acid (125 mg). Cefuroxime is a second-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis, leading to the death of susceptible bacteria. Clavulanic Acid is a beta-lactamase inhibitor that protects Cefuroxime from degradation by beta-lactamase enzymes produced by certain bacteria, thereby extending its spectrum of activity.
