Chemotherapy Week 3 Flashcards
(42 cards)
2 Forms of Chemotherapy
Antineoplastic and Cytotoxic antibiotics
Antineoplastic Drug Category and Examples
Antimetabolite: methotrexate
Mitotic Inhibitor: vincristine
Alkylating agent: cyclophosphamide
Cytotoxic Antibiotic generic drug example
doxorubicin
MOA of Chemotherapy
cytotoxic during specific cell-cycle phase
Mitotic MOA
kills cells at the start of mitosis
alkylating MOA
react chemically with parts of RNA, DNA, or cellular proteins
Hormones MOA
used in cancers sensitive to estrogen stimulation
Indication of methotrexate
acute and chronic lymphocytic leukemia, psoriasis, RA
Indication of Vincristine and doxorubicin
acute lymphocytic leukemia
indication of ALL chemo
breast/ovarian/testicular cancer and Hodgkin’s lymphoma
indication of cyclophosphamide
alkylating
-acute lymphomas, leukemia, breast/ovarian/bladder cancers
SE AE of ALL chemo drugs
Alopecia, N/V, anorexia, diarrhea, stomatitis, low WBC, and decreased bone marrow suppression
Cyclophosphamide SE/AE
peripheral neuropathy, ototoxicity, nephrotoxicity
Doxorubicin SE/AE
acute cardiac toxicity
-left ventricular failure cardiomyopathy, HF
Interactions with Methotrexate
ASA, NSAIDS leads to toxicity
Interactions with Vincristine
any drug toxic to the liver because hepatotoxicity is already an AE
Nsg implications of Chemo and assess
Infection Prevention
monitor extravasation
Avoid direct skin and eye contact w/ drug
premedicate N/V with antiemetic
assess
CBC (WBCs RBCs and platelets) UA for blood and infection, AST/ALD for liver function, kidney function BUN and creatine
Other drugs: Hydroxyurea, MOA and Indication, SE/AE, Nsg
Kills cancer cells by interrupting DNA synthesis
Tx squamous cell cancer
SE/AE- HA, hyperuricemia, nephrotoxicity
Nsg: monitor bleeding & infection
-WBC < 2,500
-Platelets < 100,000
Cancer Cell specific agent: Imatinib
MOA, indication SE/AE, Nsg
MOA: stops Ca growth by inhibiting enzymes
indication: tx of adults with chronic myelocytic leukemia
SE AE: N/V, HF, Edema
Hormone Modulators:
Selective Estrogen Receptor modulator AND
Progestin
Tamoxifen
and
medroxyprogesterone
MOA of hormone modulators
as antineoplastics, they block receptors and prevent cancer growth that are sensitive to a specific hormone (estrogen)
TX metastatic breast Ca
hormone modulators selective estrogen receptor: tamoxifen
and progestin SE AE and Nsg
Menopause like - hot flashes, vag dryness, moody, depression
endometrial Cancer, GI toxic, CVA, hypercalcemia, DVT and PE
Nsg
take with Ca and Vit D because lowered calcium = osteoporosis
Extravasation
leaks of antineoplastic drugs into surrounding tissues during IV
permanent tissue damage resulting in skin grafts, surgery, amputation
Nsg extravasation
stop infusion ASAP, and aspirate any remaining drug, do not remove the catheter, contact the pharmacist and provider
apply sterile dressings, elevation and rest of limp
document and follow protocol
