carpapenems
imipenem
meropenem
doripenem
ertapenem
monobactam
azetreonam
carbapenems used for*
EMPIRIC THERAPY
due to broad spectrum of activity [+/- aerobic/ anaerobic*]
also hard infections to get rid of [ extended spectrum b lactamases]
imipenem use
broadest spectrum
tx enterobacter
penicillin resistant pneumonia
meropenem has
more activity against gram -
structure of carbapenem
5 A ring with S outside of the ring
metabolism of imipenem?*
add?
metabolized in kidney by renal dehydropeptidase
you add cilastatin to prevent the buildup of toxic metabolites (primaxin)
adverse effects
NVD. cross allergy w pncn
imipenem:
- can lower seizure threshold
chemical structure of monobactam
single blactam without A ring
importance of monobactams
(AZtreonam)
since it has no A ring it can be used in people with penicillin allergies!!!!
aztreonam spectrum*
AEROBIC** GRAM - RODS
Monobactam tx
serious infections [meningitis, pneumonia, sepsis]— for people allergic to pncn*
UTI
INHALATION for CF to reduce pseudomonas** infections (cayston)
