(19 cards)
Which drug binds to both inactive and activated platelets on the GPIIa/IIIb complex?
Abciximab
What are Eptifibatide and Tirofiban analogs of?
fibrinogen amino acid sequence - mediates complex
What are the three drugs in the GPIIIA antagonist class?
Eptifibatide, Abciximab, Tirofiban
What is the brand name for Vorapaxar?
Zontivity
Zontivity is part of what drug class?
PAR-1
Vorapaxar is approved for what use?
reduce risk of cardiovascular events in patients with peripheral arterial disease
Persantine is
Dipyridamole
What drug is used in combo with ASA to prevent ischemia?
Dipyridamole
Which antiplatelet inhibits uptake of adenosine ?
Dipyridamole (persantine)
Which drug is used mainly to prevent MI?
ASA
ASA works by inhibiting
synthesis of TXA2 by irreversible acetylation of COX-1 AND COX-2
What should not be taken with ASA?
nsaids
What are the three thienopyridines?
clopidogrel, prasugrel, ticlopidine
How does Prasugrel prevent aggregaton?
binding to the P2Y12 ADP receptor
Indications - ticlopidine
preention of thrombotic cardiovascular events
Tricagrelor inhibits aggregation by
blocking P2Y12ADP receptor - but shorter duration of action compared to thienopyridines
What drug interacts with clopidogrel?
PPIs - they inhibit CYP2C19, which activates clopidogrel. Can be used with other thienopyridines
If patients on clopidogrel require a PPI, what should be used?
pantoprazole
Which antiplatelet is used in patients with acute coronary syndrome?
