Oncology Flashcards
MOA cyclophosphamide?
alkylating agent
causes cross linked in DNA
SE cyclophosphamide?
haemorrhagic cystitis
myelosuppression
transitional cell carcinoma
Bleomycin MOA?
Cytotoxic antibody
degrades preformed DNA
SE bleomycin?
lung fibrosis
MOA anthracyclines e.g. doxorubicin?
cytotoxic antibodies
stabilises DNA topoisomerase II complex
inhibits DNA and RNA synthesis
Methotrexate MOA?
Antimetabolite
inhibits dihydrofolate reductase and thymidylate synthesis
SE methotrexate?
myelosuppression
mucositis
liver fibrosis
lung fibrosis
MOA 5-FU?
antimetabolite
pyrimidine analogue inducing cell cycle arrest and apoptosis by blocking thymidylate synthase
SE 5-FU?
myelosuppression
mucositis
dermatitis
MOA 6MP?
antimetabolite
purine analogue that is activated by HGPRTase, decreasing purine synthesis
SE 6MP?
myelosuppression
MOA cytarabine?
pyrimidine antagonist
antimetabolite
interferes with DNA synthesis specifically at the S phase of the cell cycle and inhibits DNA polymerase
SE cytarabine?
myelosuppression
ataxia
MOA vincristine/vinblastine?
anti-microtubule
inhibits formation of microtubules
SE vincristine/vinblastine?
vincristine: peripheral neuropathy (reversible), paralytic plus
vinblastine: myelosuppression
