Drug MOA Flashcards
What is the mechanism of increased uric acid in cancer patients?
Tumor Lysis Syndrome.
- tumor intracellular components like Ca+, K+, Phos+, and nucleic acids spill out
- purines from the nucleic acids get converted into uric acid by xanthine oxidase
Neupogen
Filgrastim
Colony Stimulating Factor will stimulate production of WBC to treat neutropenia

Marinol
Dronabinol
activating cannabinoid receptors in the CNS and inhibiting the vomiting control in the medulla oblongata
Ativan
Lorazepam
enhances GABA (an inhibitor neurotransmitter) to decrease neuronal excitability that will suppress anticipatory N/V

Tamoxifen
Selective-Estrogen Receptor Modulator for ER+/PR+ breast cancers
binds to estrogen receptors on tumors to prevent growth from estrogen binding and feeding the tumor

Selective Estrogen Receptor Modulator used for prophylaxis in select post-menopausal women
Fulvestrant
Selective Estrogen Receptor Degrader that causes the estrogen receptors to downregulate and degrade
Arimidex
Anastrozole
Aromatase inhibitor that treats postmenopausal breast cancer by blocking the peripheral conversion of of androgens to estrogens

Trastuzumab
Herceptin
binds to HER2 (oncogene) to block the dimerization to block the amplified cell growth
Lupron Depot
Leuprolide
GnRH Agonist or LH agonist that initially increase LH to increase testosterone but eventually will create a negative feedback loop to decrese testosterone production
