week 12 pharm part 2 (actual drugs) Flashcards
(33 cards)
what are the two antimetabolites
methotrexate
fluorouracil
what are the two antitumout antibiotics
doxorubicin
bleomycin
what are the two mitotic inhibitors
vincristine
paclitaxel
what is the alkylating agent
cyclophosphamide
what is the MOA of cyclophosphamide
it causes alkylation of DNA which destroys DNA in cancer cells and prevents them from being able to repair themselves
which phase does cyclophosphamide act on
any phase of the cell cycle
what is a unique adverse effect of cyclophosphamide
may cause bladder injury
what is the MOA of methotrexate
it inhibits folic acid which is required for DNA and RNA synthesis
which phase of the cell cycle does methotrexate act on
S phase
what is a unique adverse effect of methotrexate
pulmonary fibrosis
what is leucovorin rescue
its a drug used to enhance the effects of methotrexate while reducing harm to normal cells.
can also be adjunct with fluorouracil
what enzyme does fluorouracil inhibit
thymidylate syntehtase
which type of tumours do fluorouracil treat
solid tumours (with surgery and radiation as well)
what phase of the cell cycle does fluorouracil act on
s phase
between doxorubin and bleomycin, which drug will injure the lungs and which may injure bone marrow and heart
doxorubin: myelosuppression and heart damage
bleomycin: lung injury
how do the anti tumour antibiotics work
they injure cells with direct interaction with DNA, slips through DNA, binds to it and destroys it all together
which phase of the cell cycle does doxorubin act on
cell cycle phase non specific
which phase of the cell cycle does bleomycin act on
G2
what is the MOA of vincristine
it binds to tubular and disrupts mitosis (stops cells from splitting)
which cytotoxic drug is a known vesicant
vincristine
which phase of the cell cycle does vincristine act on
M phase
which phase of the cell cycle does paclitaxel act on
late G2 and M phase
what are some unique adverse effects of paclitaxel
cardiotoxicity and peripheral neuropathy
whats the main difference between antiestrogens and aromatase inhibitors
antiestrogens: blocks estrogen receptors, used for younger women
aromatase inhibitors: blocks enzyme that makes estrogen, better for post menopausal women
