  • avoid pregnancy w/ rubella & vericella for 3 months 
  • tylenol for discomfort 
  • educate 
Term

Immunosuppressants 

"-limus"

Contraindications: None given 


Nursing Implications:  

  • need contraceptive use during Tx & 12 weeks after therapy ends 
  • Take drug at same time every day 
  • Take w/ meals 
  • Use same solution consistently 
  • Specific instructions to mix 
Term

Tumor Necrosis Factor - α Blocking Agent 

"-mab", "-cept"

Definition

Action:  Neutralizes the activity of tumor necrosis factor - alpha 


Drug: 

  • infliximab (Remicade) 


Use: rheumatoid arthritis / Chrohn's disease 


Adverse Effects: headache / dizziness / fatigue / anxiety / fever / rash 


Contraindications: None given 


Nursing Implications:  

  • Aminister immediately after reconstituion 
  • do not breastfeed 
  • watch for blood in stools 
  • monitor for TB 
  • May be premedicated w/ acetaminophen or diphenhydramine 
Term

Antineoplastic Agents 

Definition

Action:  Interfere w/ cell replication, w/ supply of nutrients, genetics in the nucleus 


Characteristics:

  • cell cycle specific vs. non-cell cycle specific 
  • specific percentage of kills 
  • drug resistance
  • harmful to rapidly dividing healthy cells

Only given by certified chemotherapy nurses



Given via central line 



Adverse Effects: GI / hair loss / mucositis / anemia / bleeding / neutropenia / thrombocytopenia 

 

Nursing Implications:  

  • chemotherapy precautions from patients actively receiving chemo agents (in place up to 48 hours since last dose of therapy) 
  • common side effects (listed above) 
  • teach nutrition 
Term

Antimetabolites

Definition

Action:  specific to a cell cycle --> enter cancer cells & deprive the cell of substances needed for formation of DNA 


Drug: 

  • methotrexate (Rheumatrex)
  • fluorouracil (5-FU)


Use: effective against rapidly growing tumors 


Adverse Effects: bone marrow suppression / mucositis / GI ulcerations / alopecia 

 


Nursing Implications:  

For Methotrexate:

  • Avoid alcohol
  • Avoid aspirin 
  • avoid sunlight 
  • Excreted by kidneys 
For 5-FU: 
  • Drink plenty of water 
Term

Plant Alkaloids

Definition
  • originate from vinca genus plant
  • are cell cycle specific 

Action:  stop mitosis


Drug:

Use: Hodgkin's Lymphoma / Acute Lymphoblastic Leukemia (ALL)


Adverse Effects: severe tissue damage w/ inflitrate (extraversation) / peripheral nerve toxicity / alopecia / mucositis (stomatitis - in mouth) 


Contraindications: hepatic impairment 


Nursing Implications:  

  • prepare patient for side effects
  • start anti-emetics (anti-vomiting) before & maintain them on a schedule 
  • Eat 
  • alopecia solutions
  • Urge use of soft tooth brush, rinsing, drinking fluids, & using systemic analgesics to combat mucositis 
  • Watch for bleeding 
Term

Alkylating Agents

Definition
  • developed from mustard gas agents

Action:  Interfere w/ cell division and structure of DNA during ALL phases of cell cycle


Drug: 

  • cyclophoshamide (Cytoxan)
  • cisplatin (Platinol) 


Use: wide spectrum of malignancies / hematological & solid cancers (Platinol) 


Adverse Effects: cystitis (Cytoxan) / N/V, nephrotoxicity, ototoxicity (Platinol) 


Contraindications: None given 


Nursing Implications:  

For Cytoxan:

  • take on empty stomach
  • increase fluids 
For Platinol:
  • check renal function 
Term

Anti-Tumor Antibiotics 

Definition

Action:  Bind to DNA and block DNA & RNA transcription 


Drug: 

  • doxorubicin (Adriamycin) 


Use: leukemia, breast, lung, & ovary cancer


Adverse Effects: bone marrow depression / GI / cardiotoxicity / tissue necrosis w/ IV infiltrate / alopecia 


(hepatic impairment increases these effects) 


Contraindications: None given 


Nursing Implications:  

  • May turn urine red
  • check for edema & SOB 
Term
