ACS pt 2 contd Flashcards
rogers
what is cangrelor?
IV option of P2Y12 inhibitor
platelet inhibition with 2 minutes
very expensive
when should cangrelor be used?
during a PCI when a patient did not receive loading P2Y12 inhibitor
when is DAPT recommended?
12 months in STEMI or NSTEMI/UA patients
always aspirin and P2Y12 inhibitor with loading dose and maintenance
what is the dosing of clopidogrel (plavix)?
300-600mg
75mg daily
what is dosing of ticagrelor (brilinta)?
loading: 180mg
maintenance: 90mg BID
what is the dosing of prasugrel (effient)?
loading: 60mg
maintenance: 10mg daily
what is the dosing of cangrelor?
loading: 30mcg/kg IV, followed by 4mcg/kg/min for 2 hours
maintenance: not recommended, use oral agent
why is the 600mg of clopidogrel preferred?
results in greater, more rapid, and more reliable platelet inhibition compared to 300mg
when would a 300mg loading dose of clopidogrel be preferred?
when a patient is on a fibrinolytic and under the age of 75
when is no loading dose of clopidogrel required?
if a patient is over 75 and on a fibrinolytic
what are the SE of ticagrelor (brilinta)?
dyspnea (SOB)
ventricular pauses
what P2Y12 inhibitors have greater inhibition of platelet aggregation?
ticagrelor and prasugrel
what enzyme converts clopidogrel?
CYP2C19
when is prasugrel (effient) CI?
in pts with history of TIA/stroke
when is prasugrel (effient) not recommmended?
in patients over 75 years old, under 60kg, or have a high bleeding risk
maintenance dose of 5mg may be used if deemed necessary
what P2Y12 inhibitor drugs are recommended in ischemia guided strategy?
ticagrelor and clopidogrel preferred
why would a person switch from clopidogrel to either ticagrelor or prasugrel?
inadequate response due to genetics or CV events
why would a person switch from ticagrelor to clopidogrel?
bleeding
cost
SOB
adherence
why would a person switch from prasugrel to clopidogrel?
bleeding
cost
stroke/TIA
when treating via early invasive strategy for NSTEMI/UA, what P2Y12 inhibitor should be used?
any is fine
preference for ticagrelor or prasugrel
for a STEMI pt, what P2Y12 inhibitors are preferred?
if taking fibrinolytic, clopidogrel
if had PCI, ticagrelor or prasugrel preferred
what is the counseling points of aspirin?
need to take lifelong to prevent heart attack
take with food
risk of bleeding
what is the counseling points for generic P2Y12 inhibitor?
take with aspirin for one year to prevent heart attack
risk of bleeding
what is the counseling points for specifically ticagrelor?
take 12 hours apart
let doctor know if experience SOB
