Fitz - Antimitotic/microtubule drugs & Drugs that break DNA strands Flashcards
inhibit tubulin polymerization > block assembly of microtubules
Vinca alkaloids - start with “vin”
enhance tubulin polymerzation > stabilize microtubules
taxanes - “tax” in middle
tx: vinblastine

phase of the cell cycle that vinca alkaloids and taxanes act at
M phase
sub for vincristine when neuropathy is severe
vinbastine
mode of MDR to vinca alkaloids and taxanes
increased expression of P-glycoprotein > increased extrusion of drug from cells
vinca alkaloids and taxanes administration and metabolism
