It binds to DNA and inhibits nucleic synthesis.
INDICATIONS
Acute lymphoblastic leukemia, acute myeloblastic leukemia,
Wilms tumor, neuroblastoma, soft tissue and bone sarcomas,
breast carcinoma, ovarian carcinoma, transitional cell bladder
carcinoma,. thyroid carcinoma, lymphomas of both Hodgkin
and non-Hodgkin types, bronchogenic carcinoma and gastric
carcinoma.
CONTRAINDICATIONS:
Treatment is contraindicated in patients who receive previous
treatment with complete cumulative doses of Doxorubicin
Hydrochloride and/or Daunorubicin and also in patients who
have marked myelosuppression, or those at risk of cardiac
diseases.
PREGNANCY:
Safety for use during pregnancy not established. Use only
when the potential benefits outweigh the potential hazards
to the fetus.
DRUG INTERACTIONS:
The drug may potentiate the toxicity of the other antineoplastics.
Exacerbation of cyclphosphamide-induced hemorrhagic cystitis
and enhancement of the hepatotoxicity of 6 mecraptopurine
have occurred. Barbiturates may increase the total plasma
clearance of Doxorubicin Hydrochloride. Serum levels of
digoxin may be decreased by combination chemotherapy (including
Doxorubicin Hydrochloride).
ADVERSE REACTIONS:
The major dose-limiting toxicities are myelosuppression
and cardiotoxicity.
OVERDOSAGE
Acute overdosage enhance the toxic effects of mucositis,
leukopenia and thrombocytopenia. Treat the severely myelosuppressed
patients by hospitalization, antibiotics, platelet and granulocyte
transfusions and give symptomatic treatment of mucositis.
DOSAGE AND ADMINISTRATION:
For IV use only.
Recommended dosage schedule based on body surface area :
60 to 75 mg/m2 as a single IV injection administered
at 21 day intervals. Give the lower dose to patients with
inadequate marrow reserves due to old age, prior therapy
or neoplastic marrow infiltration.
Alternative dose schedules : 30 mg/m2 on each
of 3 successive days repeated every 4 weeks. Another alternative
dose schedule is weekly doses of 20 mg/m2 which
may produce a lower incidence of CHF.
Dosages in patients with elevated bilirubin : Serum bilirubin
1.2 to 3 mg/dl give 50 % of normal dose;>3mg/dl, give
25% of normal dose.
