Uses

What is cefadroxil used for?

Cefadroxil is part of a class of antibiotics known as cephalosporins, specifically a first-generation cephalosporin. Cephalosporins are chemically related to penicillin, and work by binding to penicillin-binding proteins (PBPs) that are embedded on certain bacterial cell walls. This binding prevents normal crosslinking and results in a weakened cell wall that ruptures and kills the bacteria.

Cephalosporins have the same mechanism as penicillin, however, have enhanced resistance against β-lactamases.

Cefadroxil is a broad-spectrum antibiotic mainly indicated for:

  • Skin and skin structure infections
