  • 3rd side (hint)
What do you use to monitor heparin? enoxaparin? warfarin?
Hep: PTT
enox: don't need to monitor
Warfarin: PT
Rapid reversal of heparin? warfarin?
hep: protamine sulfate
warf: IV vit K and fresh frozen plasma
How do you administer/where does it act for hep and warf?
Hep: IV acts in blood
Warf: oral acts in liver
Between hep and warf, which is teratogenic
warfarin (because it crosses the placenta)
Which is for acute decoag (DVT, PE, MI, stroke) and which is for chroinc anticoag (post STEMI)?
Hep for acute
Warf for chronic
(think about how each acts)
What do you use in Heparin Induced Thrombocytopenia?
Lepirudin, Bivalirudin

how do they work?
directly inhibit thrombin
what drugs can be used in early MI or early ischemic stroke?
Thrombolytics: streptokinase, urokinase, tPA (alteplase)
In whom are thrombolytics contraindicated?
what do you treat toxicity with?
pts with a history of bleeds or pt with recent surgery

Aminocaproic acid
inhibit platelet aggregation by irreversibly blocking ADP receptors thus preventing GpIIb/IIIa expression?
clopidogrel and ticlopidine

used for?
Acute coronary syndrome, stenting
phosphodiesterase III inhibitor which increases cAMP in platelets thus inhibiting aggregation?
cilostazol, dipyridamole

used for?
intermittent claudication, coronary vasodilation, prevention of strokes, angina (since also a vasodilator)
GpIIb/IIIa direct inhibition?
what drug types block DNA synthesis?
Antimetabolites and Etoposide
What drug types block G2?
bleomycin and etoposide
What drugs block mitoses?
Vinca alkaloids and taxols
folic acid analog that inhibit dihydrofolate reductase?

1) myelosuppression (rescued by leucovorin)
2) Macrovesicular fatty change in liver
3) Teratogen (neural tube defects)
pyrimidine analog which inhibits thymidylate synthase

myelosuppression not rescued by leucovorin
purine (thiol) analog that decrease de novo purine synthesis
6-mercaptopurine AND 6-thioguanine

what substance increases 6-MP toxicity?
pyrimidine analog that inhibits DNA polymerase
cytarabine (ara-C)
intercalates in DNA?
Actinomycin D

used for?
Childhood tumors: Wilm's, Ewing's sarcoma, rhabdomyosarcoma
Generate free radicals and non-covalently intercalates in DNA
Doxorubicin and daunorubicin

Cardiotoxicity (dilated cardiomyopathy),
myelosuppression and alopecia
induces free radical formation

pulmonary fibrosis, skin changs
inhibits topoisomerase II which increases DNA degradation
Drugs used for testicular cancer?
Etoposide, Bleomycin and cisplatin
(eradicate ball cancer)
What does cyclophosphamide need to be activated?
bioactivation by liver

toxicity of cyclo
hemorrhagic cystitis
used for brain tumors since they cross the bbb?
Nitrosoureas (carmustine, lomustine, streptozocin)
alkalates DNA?

pulmonary fibrosis and hyperpigmentation
alkaloids that bind to tubulin in M-phase and block polymerization of microtubules so that mitotic spindle cannot breakdown
Vincristine and Vinblastine

peripheral neuropathy (crist), bone marrow suppression (blast)
hyperstabilize polymerized microtubules in M-phase so spindle can't breakdown

used for?
ovarian and breast cancers
cross link DNA
Cisplatin, carboplatin

nephrotoxic and acoustic nerve damage
inhibits ribonucleotide reductase thus decreasing dna synthesis

used in?
Sickle cell, melanoma, CML
triggers apoptosis

used for?
cancers and immunosuppression
SERMs act how in breast/bone?
antagonist in breast (used in breast cancer)
agonist in bone (fights osteoporosis)
which of the SERMs is a partial agonist at the endometrium?

therefore what happens?
increased risk of endometrial carcinoma and hot flashes

(raloxifene doesn't have these side effects)
monoclonal antibody against HER-2 (a tyrosine kinase) Used in metastatic breast cancer

monoclonal antibody against CD-20 (B-cell neoplasms)
what is synergistic with methotrexate?
