gentamicin Flashcards
type of abx?
aminoglycoside
moa
inhibits protein synthesis by binding onto 30 subunit and enters bacterial cells by using oxygen transporter system - not present in anaerobes and streptococci so utility here is futile.
can be enhanced with pencillin by increases bacterial uptake as it weakens cell walls
uses
arerobic infections - pseudonoma aerginosa endocarditis sepsis intrabdominal sepsis pyelonephritis and complicated UTI
AE
ototoxicity -build up of drug in hair cells
irreversible
nephrotoxicity- renalepithheliel cell build up- decrease output increase creatinine and urea
ci
deafness
renal impairment
elderly
neonates
precaution
check hearing and renal function prior and after and during
monitor carefully using Hartford nomogram
in obese, use dose based on ideal weight to prevent overdosing
myanthesia gravis due to impaired neuromuscular transmission
drug interactions
increase risk of ototoxicity if given with diuretics such as furosemide
increased nephrotoxicity with nephrotoxic drugs, chemotherapy, platinuim, cephalopsori and vancomycin
