Concern with cephalosporins:
may cross react with PCN allergy

Concern with aminoglycosides
highly toxic

Concern with gentamycin and tobramycin
toxic (oto, nephro, neuro)

Function of clavulonic acid when added to PCN.
inhibits penicillinase enzyme that is responsible for resistance

Name a drug with prolonged antibiotic effect:

List the four mechanisms of drug resistance:
degrade the drug, bind the drug, mutate, efflux pumps (pump drug out of cell)

Aminoglycosides gentamicin, streptomycin, tobramycin, neomycin, kanamycin, amikacin (BE CAREFUL WITH THESE “mycins”. They’re not macrolides) Aminoglycosides – gram (-) Bactericidal Aminoglycosides *treat aerobic bacteria such as escherichia coli and klebsiella species *they inhibit protein synthesis in bacteria and compromise the …
