Study Notes
Classification of Cefalosporins
- Cefepime: Fourth generation; known for broad-spectrum activity, particularly against Gram-negative bacteria.
- Cefuroxime: Second generation; effective against respiratory tract infections and has some resistance to β-lactamases.
- Cefazolin: First generation; often used for surgical prophylaxis, effective against Gram-positive cocci.
- Cefotaxime: Third generation; good penetration into the central nervous system, used for severe infections such as meningitis.
- Ceftaroline: Fifth generation; specifically targets MRSA (methicillin-resistant Staphylococcus aureus) and other resistant strains.
- Ceftazidime: Third generation; particularly effective against Pseudomonas aeruginosa and useful in treating nosocomial infections.
- Cefalexin: First generation; commonly used for skin and soft tissue infections, well absorbed orally.
- Ceftriaxone: Third generation; often used for treating gonorrhea and has a long half-life, allowing for once-daily dosing.
- Cefoxitin: Second generation; effective against anaerobic bacteria, often used in intra-abdominal infections.
- Cefaclor: Second generation; effective against various infections, particularly in respiratory and urinary tracts.
