Q

Vinca Alkaloid Information

A
  • Box warning: vesicants, for IV administration ONLY

- SE: Peripheral sensory neuropathy, autonomic neuropathy

17
Q

Doxetaxel

A
  • Taxane
  • Premedicate for HSR with steroids x3d prior to tx
  • Can cause severe fluid retention
18
Q

Paclitaxel

A
  • Taxane
  • Doesn’t require premedication for HSR
  • Okay to use PVC bag/tubing
  • Use 0.22 micron filter
19
Q

Taxane Information

A
  • Box warning: severe allergic rxn
  • Allergic rxn are due to solvent system, not the drug
  • Use non-PVC bag and tubing
  • Give BEFORE platinum-containing compound (reduces taxane elimination)
20
Q

5-FU

A
  • Fluorouracil, Pyrimidine analog antimetabolite

- Given with leucovorin to increase efficacy

21
Q

Xeloda

A
  • Capecitabine, Pyrimidine analog antimetabolite
  • Oral prodrug of 5-FU
  • DPD deficiency increases risk of severe toxicity
  • Take with food
22
Q

Pyrimidine Analog Antimetabolite SE

A
  • Hand-foot syndrome
  • Diarrhea
  • Mucositis
23
Q

Trexall

A
  • MTX, Folate Antimetabolite
  • Leucovorin used as rescue in high-dose regimens
  • Levoleucovorin is also a rescue option
  • Hydration and IV Na-bicarbonate must be given to alkalize urine and decrease nephrotoxicity risk
  • NSAIDs and salicylates decrease its clearance
24
Q

Glucarpidase

A
  • Antidote for MTX
  • Lowers levels of MTX when toxicity/overdose is occurring
  • Used when hydration/alkalization isn’t adequate
25
Q

Folate Antimetabolite Information

A
  • Box Warning: Myelosuppression, renal damage, hepatotoxicity, GI toxicity, teratogenic
  • SE: Nephrotoxic, hepatotoxic, nausea, mucositis

28
Q

Cetuximab

A
  • Targets EGFR
  • Must test for KRAS wildtype to use
  • SE: Acneiform rash

  • Avoid sunlight, use sunscreen, topical steroids and abx can be used to reduce skin damage
29
Q

Rituxin

A
  • Rituximab
  • Targets CD antigens, inhibits them
  • Premedicate with Benadryl, APAP, and steroid
