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
MOA docetaxel?
anti-microtubule
prevents microtubule depolymerisation and disassembly
decreasing free tubular
SE docetaxel?
neutropenia
MOA irinotecan?
topoisomerase inhibitors
inhibits topoisomerase I, prevents relaxation of supercoiled DNA
SE irinotecan
myelosuppresion
Cisplatin MOA?
causes cross linking in DNA
SE cisplatin?
ototoxicity, peripheral neuroapathy, hypomagnesaemia
MOA hydroxyurea (hydroxycarbamide)
inhibits ribonucleotide reductase
less DNA synthesis
SE hydroxyurea?
myelosuppression
