Introduction

A semi-synthetic cephalosporin antibiotic.

Uses

Cefradine is a first-generation cephalosporin antibiotic used in the treatment of bacterial infections of the respiratory and urinary tracts and of the skin and soft tissues.

Associated Conditions

  • Bacterial Sepsis
  • Bloodstream Infections
  • Osteomyelitis
  • Peritonitis
  • Respiratory Tract Infections (RTI)
  • Septic Arthritis
  • Skin and Soft Tissue Infections
  • Urogenital infection bacterial

Mechanism of Action

Cefradine is a first generation cephalosporin antibiotic with a spectrum of activity similar to Cefalexin. Cefradine, like the penicillins, is a beta-lactam antibiotic. By binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, it inhibits the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins; it is possible that Cefradine interferes with an autolysin inhibitor.

Route of Elimination

Over 90 percent of the drug is excreted unchanged in the urine within six hours.

Food Interactions
