9
Q
penicillin MOA + origin
A
- obtained from mold
- bactericidal
- disrupts cell wall synthesis which kills the cell
10
Q
cephalosporins MOA + generations + whats drug does this drug substitute and why?
A
- disrupts cell wall synthesis
- bactericidal
- 4 generations
- substitute for penicillin when allergy
11
Q
cephalosporins adverse effects
A
- GI disturbances
- nephrotoxicity
- doesn’t react with alcohol
- allergy
12
