Pharmacology for Hematology Oncology Flashcards
Heparin mechanism
cofactor for antithrombin: II, Xa decr
Used to monitor heparin
PTT
rapid reversal of heparin
protamine sulfate
Enoxaparin
LMWH
dalteparin
LMWH
mechansim, advantage of LMWH
acts on Xa, no lab monitoring, not reversible
Mechanism of HIT
antibody-heparin-PF4 complex (IgG)
Argatroban
hirudin (leech derivative)- HIT alternative
bivalirudin
hirudin (leech derivative)- HIT alternative
Used to monitor warfarin
PT
Used to reverse warfarin
Vit K, fres frozen plasma
Apixaban
Factor Xa inhibitor
rivaroxaban
Factor Xa inhibitor
Aminocaproic acid
used to treat thrombolytic toxicity

TNK-tPA, thrombolytic
Aspirin overdose
respiratory alkalosis superimposed by metabolic acidosis
Clopidogrel
irreversible ADP receptor and GPIIb/IIIa inhib
ticopidine
irreversible ADP receptor and GPIIb/IIIa inhib
Prasugrel
irreversible ADP receptor and GPIIb/IIIa inhib
ticagrelor
irreversible ADP receptor and GPIIb/IIIa inhib
Use of ADP receptor inhibitors (3)
acute coronary syndrome, coronary stenting, thrombotic stroke prevention
Toxicity of ADP receptor inhibitors
neutropenia, TTP/HUS
cilostazol
PDEIII inhib
dipryrimadole
PDEIII inhib
Mechanism of PDEIII inhib
Incr cAMP in platelets, inhib plt aggregation, vasodilation
use of PDEIII Inhib
intermittent claudication, coronar vasodilation, prevent stroke, TIA, angina
Toxicity of PDEIII inhib
Nausea, headache, facial flushing, hypotension, abd pain
Abciximab
GPIIb/IIIa inhib (monoclonal Ab)
Eptifibatide
GPIIb/IIIa inhib
Tirofiban
GPIIb/IIIa inhib
Leucovorin use
reverses myelosuppresion assoc with MTX (folinic acid)
MTX mechanism
Folic acid analog; inhib dihydrofolate reductase; decr dTMP
MTX uses
leukemia, lymphoma, choriocarcinoma, sarcoma
MTX toxicity
myelosuppression, macrovesicular fatty change in liver, mucositis, teratogenic
5-FU mechanism
pyrimidine analog; inhibits thymidylate synthase
5-FU uses
colon cancer, pancreatic cancer, basal cell
5-FU toxicity
myelosuppression, photosensitivity
cytarabine mechanism
pyrimidine analog
cytarabine uses
leukemia, lymphoma
cytarabine toxicity
leukopenia, thrombocytopenia, megalobastic anemia
6-MP, 6-TG mechanism
purine (thiol) analog
