Protein Synthesis Inhibitors Flashcards
MOA targets
50s or 30s
MOR
efflux, target site modification, drug inhibition
all are bacteriostatic except
aminoglycosides (and some macrolides)
when used?
BL allergy/resistance, intracellular pathogen, no cell wall, in combo with BL
which are 30s
tetracycline, aminoglycosides
tetracycline drug
doxyclycine, “the tick drug”
doxyclycine MOR
efflux. also altered binding
doxyclycineMOA
reversible 30s bind, block tRNA binding. intracellular, well distributed
doxyclycine spectrum
gram +, -, spirochetes, chlamydia
doxyclycine clinical
acne, URI, STD, tick, community MRSA
doxyclycine adverse
yellow teeth, GI, photosensitivity
aminoglycosides drug
gentamicin
gentamicin MOA
30s irreversible bind, prevent translocation
gentamicin MOR
inactivate enzyme. also efflux and binding site mutation
gentamicin spectrum
gram - bacilli (PSEUD), can be used in synergy with enterococci
