cipro/levo/gemifloxacin by kidneys

moxifloxacin by liver

22

A

ciprofloxacin

levofloxacin

24

A

levo and moxifloxacin

26
Q

Adverse effects of fluroquinolones

A 
QT prolongation
tendonitis/ruptured tendons (cartilage deg)
peripheral neuropathy (inhibits GABA in CNS)
photosensitivity
27
Q

MOA of macrolides

A

attaches to 50s subunit of ribosome
no protein synthesis
bacteriostatic
affinity for domain V of 23s RNA

28
Q

MOA of ketolides

A

binds 50s rRNA

binds domain V and domain II of 23s RNA

29
Q

Resistance to macrolides

A

decreased permeability/increased efflux (gram +)
methylation of binding site (erm gene, gram +)
hydrolyzation by esterases at lactone ring (ere gene)

30
Q
