Cephalosporins are a widely used class of antibiotics that belong to the beta-lactam family. They are effective against a broad spectrum of bacterial infections and are often chosen for their safety profile and efficacy. Understanding the common brand names and formulations of cephalosporins is essential for healthcare professionals and students alike.

Overview of Cephalosporin Generations

Cephalosporins are categorized into five generations based on their spectrum of activity and resistance to beta-lactamases. Each generation has specific brand names and formulations that are widely recognized in clinical practice.

First-Generation Cephalosporins

First-generation cephalosporins are primarily effective against gram-positive bacteria. They are commonly used for skin infections, surgical prophylaxis, and respiratory tract infections.

  • Cefadroxil – Brand name: Duricef
  • Cephalexin – Brand name: Keflex, Keftab

Second-Generation Cephalosporins

Second-generation cephalosporins have increased activity against gram-negative bacteria and are often used in respiratory tract infections and surgical prophylaxis.

  • Cefuroxime – Brand name: Ceftin, Zinacef
  • Cefaclor – Brand name: Ceclor
  • Cefotan (Cefotetan) – Brand name: Cefotan

Third-Generation Cephalosporins
