Study Notes
Cephalosporin Classes Overview
- Cephalosporins are classified into generations based on their spectrum of activity and chemical structure.
- Each generation has different effectiveness against bacteria and is used for various infections.
1st Generation Cephalosporins
- Primarily effective against Gram-positive bacteria and some Gram-negative bacteria.
- Common agents include:
- Cephazolin: Often used for surgical prophylaxis.
- Cephalexin: Administered for skin infections and respiratory tract infections.
- Cefadroxil: Similar uses to Cephalexin, available in a once-daily dosing form.
2nd Generation Cephalosporins
- Broader spectrum against Gram-negative bacteria compared to the first generation.
- Key agents include:
- Cefoxitin: Effective against anaerobes; commonly used in intra-abdominal infections.
- Cefaclor: Used for respiratory tract and urinary tract infections.
- Cefprozil: Used for skin and respiratory infections, effective against certain resistant strains.
- Cefuroxime: Used for respiratory, ear, and skin infections; has oral and injectable forms.
- Cefotetan: Noted for effectiveness against anaerobic bacteria.
- Cefamandole: Can be used in serious infections, though less commonly prescribed now.
3rd Generation Cephalosporins
- Increased Gram-negative coverage, including some strains resistant to earlier generations.
- Main agents include:
- Ceftriaxone: Broad-spectrum; often used in severe infections such as meningitis.
- Cefotaxime: Commonly utilized for various infections, including sepsis.
- Cefpodoxime: Available orally, used for respiratory and urinary tract infections.
- Ceftibuten: Effective for respiratory infections, convenient oral form.
- Cefdinir: Used for skin infections and otitis media in children.
- Ceftizoxime: Has a broad-spectrum coverage; effective against resistant strains.
- Ceftazidime: Notable for activity against Pseudomonas aeruginosa.
4th Generation Cephalosporins
- Extended spectrum, with effectiveness against both Gram-negative and Gram-positive bacteria, as well as resistant strains.
- Cefepime: Used in serious infections and for hospital-acquired pathogens; provides broad-spectrum coverage.
5th Generation Cephalosporins
- Designed to combat resistant Gram-positive bacteria, including MRSA.
- Ceftaroline: The only cephalosporin effective against MRSA; used in skin infections and community-acquired pneumonia.
