Which generation of cephalosporin is more effective?
Third-generation cephalosporins are more effective against Gram-negative bacteria compared to both the first and second generations. They’re also more active against bacteria that may be resistant to previous generations of cephalosporins.
HOW DO third generation cephalosporins differ from earlier cephalosporins?
Third-generation cephalosporins are more effective against gram-negative bacteria than the first and second generations. They are usually effective against bacteria that may be resistant to previous generations of cephalosporins.

How do you remember the spectrum of antibiotics?
Tips for Memorizing Antibiotic Spectrum of Activity
- Daptomycin is inactivated by lung surfactant – don’t use in pneumonia.
- Linezolid is bacteriostatic – don’t use in bloodstream infections (although it can be used for VRE bacteremia)
- Ceftaroline is vancomycin and ceftriaxone rolled into one loveable fuzzball.
Which is stronger cephalexin or cefdinir?
The usefulness questionnaire demonstrated that cefdinir was more highly rated in the mean composite score (87.4 vs. 83.6, p = 0.04), with the difference primarily due to the respondents’ preference for the convenience of taking the study medication (mean score 93.5 vs. 74.1 for cephalexin, p < 0.001).
