omacetaxine

(oh′ma-set-ax′een)

Synribo

Func. class.:
Antineoplastic-miscellaneous

Chem. class.:
Cephalotaxine ester (derived from the Evergreen tree:
Cephalotaxus harringtonia)

ACTION:

Inhibits protein synthesis by binding to site of large ribosome subunit, it reduces Bcr-Abl and Mcl-1 independent of direct Bcr-Abl binding, inducing apoptosis

USES:

Chronic or accelerated phase chronic myelogenous leukemia (CML) with resistance or/and intolerance to 2 or more tyrosine kinase inhibitors

CONTRAINDICATIONS:

Pregnancy (D), breastfeeding, hypersensitivity

Precautions:
Children, bleeding, diabetes mellitus, female patients, geriatric patients, hyperglycemia, hyperosmolar hyperglycemic state (HHS), infection, anemia, neutropenia, thrombocytopenia

PHARMACOKINETICS

Protein binding ≤50%, half-life 6 hr, peak 30 min

INTERACTIONS

Increase:
Bleeding risk—anticoagulants, salicylates, NSAIDs, avoid use when platelets are <50,000 cells/mL

NURSING CONSIDERATIONS
Assess:

 

Black Box Warning:

CBC, differential, platelet count before treatment and weekly, during induction/maintenance, then every 2 wk as needed

 
Pregnancy D:
assess for pregnancy before starting treatment

 
Infection:
monitor temp every 4 hr; fever might indicate beginning of infection

• 
CV status: B/P, edema, flushing

• 
CNS changes: confusion, paresthesias, dysesthesia, pain, weakness

 
Hypersensitive reactions, anaphylaxis:
hypotension, dyspnea, angioedema, generalized urticaria; discontinue infusion immediately

 
Bone marrow depression/bleeding:
hematuria, guaiac, bruising or petechiae, mucosa or orifices every 8 hr; obtain prescription for viscous lidocaine (Xylocaine); avoid invasive procedures

• 
Effects of alopecia on body image; discuss feelings about body changes

• 
Diabetes mellitus:
avoid in poorly controlled disease, monitor blood glucose levels frequently

Evaluate:

• 
Therapeutic response: decreased CML, positive hematologic response

Teach patient/family:

• 
To report signs of infection: fever, sore throat, flulike symptoms

• 
To report signs of anemia: fatigue, headache, faintness, SOB, irritability

• 
To report bleeding; to avoid use of razors, commercial mouthwash

• 
To avoid use of aspirin, ibuprofen

• 
That hair may be lost during treatment; that a wig or hairpiece might make patient feel better; that new hair may be different in color and texture
