Q

What are the inhibitors of intermediary metabolism?

PO or IV or Both?

A

Sulfonamides
TMP-SMX - both
TMP - PO

17
Q

Do cell wall inhibitors work on atypical bugs? Why?

A

No, atypical bacteria do not have cell walls, so cell wall inhibitors don’t do anything to them

18
Q

What antibiotics are eliminated by non renal mechanisms?

A 
D CRIMES
Doxycycline
Clindamycin
Rifampin
Isoniazid
Erythromycin-like (macrolides)
Sulfonamides (TMP-SMX)
19
Q

Antibiotics eliminated by non-renal mechanisms have what complications?

A

Potential for drug drug interactions
Genetic polymorphisms in metabolizing enzymes
Potential for hepatotoxicity

20
Q

What antibiotic mechanisms are bactericidal?

A

Inhibition of cell wall synthesis
Disruption of cell membrane function
Interference with DNA function or sythesis

21
Q

What antibiotic mechanisms are bacteriostatic?

A

Inhibition of protein synthesis (except for aminoglycosides, they’re bactericidal)
Inhibition of intermediary metabolic pathways

22
Q

What are the gram + cocci?

A

Streptococci, staphylococci, enterococci

23
Q

What are the gram - cocci?

A

Neisseria (meningitidis, gonorrhoeae) and M. catarrhalis

24
Q

What are the gram - rods?

A

E. coli, pseudomonas, H. influenzae

25
Q

What is a gram + rod?

A

Listeria

26
Q

What anaerobes are of most concern?

A

Gram + rods = C. diff, H. pylori

Gram - rods = Bacteroides fragilis

27
Q

What are the atypical bacteria?

A

Chlamydia, Mycoplasma, Rickettsia

28
Q

What does it mean to be narrow spectrum?

A

Effective against either gram + OR gram -

29
Q

What does it mean to be extended spectrum?

A

Effective against gram + AND gram -

30
Q

What does it mean to be broad spectrum?

A

Effective against gram + AND gram - AND atypical

31
Q 
Some drugs selectively accumulate. Where do the following accumulate and is it good or bad?
Clindamycin
Macrolides
Tetracyclines
Nitrofurantoin
Aminoglycosides
A

Clindamycin - Bone, good for osteomyelitis
Macrolides - lungs, good for URIs/pneumonia
Tetracyclines- gingiva and sebum (good for periodontitis and acne). Also Ca++ in a bad way that is bad for bone development and teeth in children
Nitrofurantoin - Urine, good for UTIs
Aminoglycosides- Inner ear and renal brush border, bad(causes ototoxicity and nephrotoxicity)
