Indications
In combination with other antineoplastics in the treatment
of leukemias.
Action
Forms a complex with DNA, which subsequently inhibits
DNA and RNA synthesis (cell-cycle phase-nonspecific).
Therapeutic Effects: Death of rapidly replicating
cells, particularly malignant ones. Also has
immunosuppressive properties.
Pharmacokinetics
Absorption: Administered IV only, resulting in complete
bioavailability.
Distribution: Widely distributed. Crosses the placenta.
Metabolism and Excretion: Extensively metabolized
by the liver. Converted partially to a compound
that also has antineoplastic activity (daunorubicinol);
40% eliminated by biliary excretion.
Half-life: Daunorubicin —18.5 hr. Daunorubicinol—
26.7 hr.
TIME/ACTION PROFILE (effects on blood
counts)
ROUTE ONSET PEAK DURATION
IV 7–10 days 10–14 days 21 days
Contraindications/Precautions
Contraindicated in: Hypersensitivity to daunorubucin
or any other components in the formulation;
Symptomatic HF/arrhythmias; Pregnant or lactating
women.
Use Cautiously in: Active infections or decreased
bone marrow reserve; Geriatric patients or patients
with other chronic debilitating illnesses (dosage reduction
recommended for patients 60 yr); May reactivate
skin lesions produced by previous radiation therapy;
Hepatic or renal impairment (dosage reduction recommended
if serum creatinine 3 m g/dL or serum bilirubin
1.2 m g/dL); Patients who have received previous
anthracycline therapy or who have underlying cardiovascular
disease (increased risk of cardiotoxicity); Patients
with child-bearing potential.
Adverse Reactions/Side Effects
EENT: rhinitis, abnormal vision, sinusitis. CV: CARDIOTOXICITY,
arrhythmias. GI: nausea, vomiting, esophagitis,
hepatoxicity, stomatitis. GU: red urine, gonadal
suppression. Derm: alopecia. Hemat: anemia, leukopenia,
thrombocytopenia. Local: phlebitis at IV site.
Metab: hyperuricemia. Misc: chills, fever.
Interactions
Drug-Drug: Additive myelosuppression with other
antineoplastics. May decrease antibody response to
live-virus vaccines and increase risk of adverse reactions.
Cyclophosphamide increases the risk of cardiotoxicity.
Increased risk of hepatic toxicity with other
hepatotoxic agents.
Route/Dosage
Other dose regimens are used. In adults, cumulative
dose should not exceed 550 mg/m2 (450 mg/m2 if previous
chest radiation).
IV (Adults 60 yr): 45 mg/m2/day for 3 days in first
course, then for 2 days of second course (as part of
combination regimen).
IV (Adults 60 yr): 30 mg/m2/day for 3 days in first
course, then for 2 days of second course (as part of
combination regimen).
IV (Children 2 yr): 25 mg/m2 once weekly (as part
of combination regimen). In children 2 yr or BSA
0.5 m2, dosage should be determined on a mg/kg basis.
Availability (generic available)
Powder for injection: 20 mg/vial. Solution for
injection: 5 mg/mL.
