28
Q

aminoglycosides (concentration/time dependent)

A

concentration dependent

29

post antibiotic effect

A

continued suppression of bacterial growth when levels are below MIC for the organism

30
Q

antibiotics with post antibiotic effect

A

aminoglycosides

31

43
Q

PCNs MOA

A

beta lactams that inhibit cell wall synthesis by binding to
