with initiating drug therapy monitor clinical responses and plasma levels use simple medication regimen,
monitor drug interaction review drug therapy dispose old medications promote adherence use beers
criteria.
Beers Criteria - correct answer -A list of medications that are generally considered inappropriate when
given to elderly people
impacts of polypharmacy - correct answer -using 5 or more medications daily leads to possible drug

Amiodarone
Ciprofloxacin
Ketocanazole (and other azoles)
Acute alcohol use
Valproate
Isoniazid
Grapefruit Juice
Sulfonamides
CYP450 inhibitors function - correct answer -slow down the metabolic activity of specific enzymes,
causing a decrease in the rate/extent of metabolism of other drugs that are substrates for those same
enzymes this can cause drug toxicity.
CYP450 inducers - correct answer -barbituates, griseofulvin, carbamazepine, rifampin, st. john wart,
chronic alcoholism, phenytoin (CRAP GPS)
