TermDefinition
thrombolytics Alteplase (tPA), reteplase (rPA), streptokinase, tenecteplase (TNK-tPA) aids plasminogen to plasmin -> cleaves thrombin and fibrin clots. -PT, PTT, no change in platelet count RX: Early MI, early ischemic stroke, direct thrombolysis of severe PE Nonspecific reversal with - anti fibrinolytics (eg, aminocaproic acid, tranexamic acid), - platelet transfusions, - factor corrections (eg, cryoprecipitate, FFP, PCC).
ADP (P2Y12) receptor blockers Clopidogrel, prasugrel, ticagrelor (reversible), ticlopidine. irreversibly block --> Prevent expression of glycoproteins IIb/IIIa on platelet surface. RX; Acute coronary syndrome; coronary stenting. - incidence or recurrence of thrombotic stroke. AVR; Neutropenia (ticlopidine). TTP may be seen.
Phosphodiesterase inhibitors Cilostazol, dipyridamole. > cAMP in platelets --> inhibition of platelet aggregation; - vasodilators. RX; Intermittent claudication, - coronary vasodilation - (dipyridamole used for cardiac stress testing), - prevention of stroke or TIAs (combined with aspirin) AVR; Nausea, headache, - facial Flushing, - hypotension, - abdominal pain
glycoprotein receptor IIb/IIIa inhibitors Abciximab, eptifibatide, tirofiban. Abciximab is made from monoclonal antibody Fab fragments. RX; Unstable angina, percutaneous coronary intervention. AVR; Bleeding, thrombocytopenia.
Dactinomycin (actinomycin D) Intercalates into DNA ---> preventing RNA synthesis. RX; Wilms tumor, Ewing sarcoma, rhabdomyosarcoma. Used for childhood tumors. Myelosuppression.
free radical formation Doxorubicin, daunorubicin - Solid tumors, leukemias, lymphomas. - AVR; CARDIOTOXIC -Dexrazoxane (iron chelating agent) used to prevent cardiotoxicity Bleomycin - Induces free radical formation breaks in DNA strand RX; Testicular cancer, Hodgkin lymphoma. What is AVR of Bleomycin Pulmonary brosis, skin hyperpigmentation. Minimal myelosuppression.
microtubules inhibitors Paclitaxel, other taxanes -Hyperstabilize polymerized microtubules - Ovarian and breast carcinomas. AVR; Myelosuppression, neuropathy, hypersensitivity. Vincristine, vinblastine - bind β-tubulin and inhibit its polymerization into microtubules Vincristine, vinblastine -Solid tumors, - leukemias, - Hodgkin and non-Hodgkin lymphomas.
Drugs for Solid tumors Doxorubicin, daunorubicin Vincristine, vinblastine Etoposide, teniposide BeVacizumab
CISPLATIN RX; Testicular, bladder, ovary, GI, and lung carcinomas. Cross-link DNA. AVR; Nephrotoxicity, Fanconi syndrome, peripheral neuropathy, ototoxicity. Prevent nephrotoxicity with - amifostine (free radical scavenger) - chloride (saline) diuresis.
Testicular CANCER Bleomycin Cisplatin Etoposide, teniposide
BeVacizumab Monoclonal antibody against VEGF. Inhibits angiogenesis (inhibits Blood Vessel formation). RX; Solid tumors (eg, colorectal cancer, renal cell carcinoma), - wet age-related macular degeneration. AVR;- Hemorrhage, blood clots, and impaired wound healing.
ERLOTINIB EGFR tyrosine kinase inhibitor. RX; Non-small cell lung cancer. . AVR; Rash
CETUXIMAB, PANITUMUMAB Monoclonal antibodies against EGFR. Stage IV colorectal cancer (wild-type KRAS), head and neck cancer. AVR; Rash, elevated LFTs, diarrhea
IMATINIB and DASATINIB Tyrosine kinase inhibitor of bcr-abl (encoded by Philadelphia chromosome fusion gene in CML) and c-kit (common in GI stromal tumors). RX; CML, GI stromal tumors (GIST). AVR; Fluid retention.
RITUXIMAB Monoclonal antibody against CD20, RX; Non-Hodgkin lymphoma, CLL, ITP, rheumatoid arthritis. AVR; risk of progressive multifocal leukoencephalopathy.
BORTEZOMIB Proteasome inhibitors, - induce arrest at G2-M phase - apoptosis. RX; Multiple myeloma, RX; mantle cell lymphoma. AVR; Peripheral neuropathy, herpes zoster reactivation.
VEMURAFENIB Small molecule inhibitors of BRAF oncogene ⊕ melanoma. VEmuRAF-enib is for V600E- mutated BRAF inhibition. co-administered with MEK inhibitors (eg, trametinib). RX; Metastatic melanoma
Heparin Immediate anticoagulation for pulmonary embolism (PE), - acute coronary syndrome, - MI, - deep venous thrombosis (DVT). Used during pregnancy (does not cross placenta). - Follow PTT. AVR: Bleeding, thrombocytopenia (HIT), osteoporosis, drug-drug interactions antidote; use protamine sulfate
Direct thrombin inhibitors Bivalirudin, Argatroban, Dabigatran (only oral agent in class). RX; - Venous thromboembolism, atrial fibrillation. - Can be used in HIT, when heparin is BAD for the patient. AVR; Bleeding; can reverse dabigatran with idarucizumab. Consider PCC and/or anti brinolytics (eg, tranexamic acid) if no reversal agent available
Warfarin Inhibits epoxide reductase, interferes with γ-carboxylation of vitamin K–dependent clotting factors II, VII, IX, X, and proteins C, S. RX; Chronic anticoagulation; - venous thromboembolism prophylaxis, - prevention of stroke in atrial fibrillation) Metabolized by cytochrome P-450.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
