Warnings
Black box warnings
The drug should be administered under the supervision of an experienced leukemia-chemotherapy physician. Physician must be capable of responding rapidly to severe hemorrhagic conditions or overwhelming infection.
Administer daunorubicin into a rapidly flowing IV infusion. Severe local tissue necrosis will result if extravasation occurs. Do not administer IM or SC.
Cumulative dosage that exceeds 400 to 550 mg/m² in adults, 300 mg/m² >2 years of age, or 10 mg/kg in children <2 years of age may result in a severe and potentially fatal myocardial toxicity including congestive heart failure; this may occur during therapy or several months to years after therapy.
Severe myelosuppression that could lead to infection or hemorrahage may occur when used at therapeutic doses
Dosage adjustment recommended in patients with renal or hepatic impairment
Contraindications
Hypersensitivity
Active infection
IM or SC administration (vesicant)
Patients who have received max cumulative dose of daunorubicin or doxorubicin
Patients with preexisting myelosuppression from other drug treatments
Cautions
Risk of severe cardiotoxicity (including CHF) & myelosuppression
Caution in hepatic/renal impairment
Children may be more sensitive to cardiotoxic effects than adults
Avoid pregnancy
Secondary leukemias reported when used in combination with radiation or chemotherapy
Pregnancy and lactation
Pregnancy category: d
Lactation: excretion in milk unknown/not recommended
Pregnancy categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.
C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.
D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.
X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.
NA: Information not available.
Pharmacology of Daunorubicin (Cerubidine)
Mechanism of action
Anthracycline; intercalates between DNA base pairs, impairs topoisomerase II function and subsequently inhibits DNA and RNA replication
Pharmacokinetics
Protein Bound: 50-60%
Half-life: 14-20 hr (parent drug), 24-48 hr (daunorubicinol)
Vd: 20-39.2 L/kg
Metabolism: Hepatic
Metabolites: DaunorubicinoL
Clearance: 17.3 mL/min
Excretion: Feces (40%) & urine (25%)
Administration
IV Incompatibilities
Additive: dexamethasone sodium phosphate, heparin
Y-site: allopurinol, aztreonam, cefepime, fludarabine, piperacillin/tazobactam
IV Compatibilities
Additive: cytarabine/etoposide, hydrocortisone Na-succinate
Y-site: amifostine, etoposide phosphate, filgrastim, gemcitabine, granisetron, melphalan, methotrexate, ondansetron, Na-bicarb, teniposide, thiotepa, vinorelbine
IV Preparation
Reconstitute 20 mg vial with 4 mL SWI to a final concentration of 5 mg/mL
IV Administration
Vesicant, never administer IM or SC
IVP: desired dose is withdrawn into a syringe containing 10-15 mL NS, then injected over 2-3 min into the tubing or sidearm of a freely flowing IV infusion of NS or D5W
Avoid small veins, swollen or edematous extremities, & areas overlying joints & tendons as inj sites
Has also been diluted in 100 mL of D5W or NS & infused over 30-45 min
Flush with 5-10 mL of IV solution before & after drug administration
Extravasation Management
Terminate injection or infusion immediately & aspirate back as much as possible
Apply cold pack w/circulating ice water, ice pack or cryogel pack to extravasation site for 15-20 min QID x 24-48 hr
Elevate site for 48 hr, then resume normal activity
Extravasation of <1-2 mL often heal spontaneously. If >3 mL, ulceration may occur.
Protect site from heat & sunlight
Varied results in studies using 99% DMSO to treat extravasation, follow institutional policy
If pain, erythema, &/or swelling persist beyond 48 hr, refer pt immediately to plastic surgeon for consultation & possible debridement
