60-75 mg/m² IV every 21 days as a single agent; 40-60 mg/m² IV every 21-28 days in combination regimens. Cumulative lifetime dose not to exceed 450-550 mg/m² (or 400 mg/m² with prior chest irradiation).
Doxorubicin HCl liposome injection 20 mg/m2 intravenously over 1 hour every 4 weeks.
Triphasic: initial α half-life 30 min (distribution), intermediate β half-life 3-4 hours (metabolism), terminal γ half-life 20-48 hours (prolonged due to extensive tissue binding and slow efflux from tissues).
Terminal half-life is approximately 30–40 hours, prolonging drug exposure and allowing every-4-week dosing.
Primarily hepatic metabolism via aldo-keto reductases to doxorubicinol; also undergoes 4-O-demethylation and glucuronidation. CYP450 minimally involved.
Primarily hepatically metabolized by aldo-keto reductases to doxorubicinol (active metabolite); also metabolized by cytochrome P450 (minor) and glycosidases.
Primarily hepatobiliary (∼50% as unchanged drug and metabolites in bile); renal excretion accounts for ∼5-12% over 72 hours; fecal elimination ~40%.
Primarily hepatic metabolism and biliary excretion; urinary excretion accounts for <10% of the administered dose as unchanged drug.
∼70% bound to plasma proteins, primarily albumin; binding is concentration-dependent and saturable at high doses.
Approximately 90% bound to plasma proteins, primarily albumin.
Extensive: 20-30 L/kg (total body water far exceeded, indicating deep tissue compartment binding, especially in liver, spleen, heart, and bone marrow).
Vd approximately 2.8 L/m² (not directly L/kg; low Vd indicates predominant plasma compartment retention).
Not bioavailable orally (0%, due to extensive first-pass metabolism and instability in GI tract); administered only intravenously.
Only intravenous administration; oral bioavailability is negligible.
No specific dose adjustment recommended for renal impairment; however, monitor for toxicity. GFR < 10 m L/min: consider dose reduction by 50% due to potential accumulation of active metabolites.
No dose adjustment required for mild to moderate renal impairment (Cr Cl ≥30 m L/min). Not recommended in severe renal impairment (Cr Cl <30 m L/min) due to lack of data.
Child-Pugh A: reduce dose by 25%; Child-Pugh B: reduce dose by 50%; Child-Pugh C: contraindicated or reduce by 75% with extreme caution.
Child-Pugh Class A: no adjustment; Child-Pugh Class B: reduce dose by 50%; Child-Pugh Class C: not recommended.
30-75 mg/m² IV every 21-28 days; cumulative dose limit 400-550 mg/m². Dose based on body surface area; for infants < 1 year or BSA < 0.5 m², use weight-based dosing: 1-2 mg/kg IV every 21 days.
Safety and efficacy not established in pediatric patients.
No specific dose adjustment based on age alone; use with caution due to increased risk of cardiotoxicity and myelosuppression. Consider starting at lower end of dosing range (e.g., 45-60 mg/m² every 21 days) and monitor cardiac function.
No specific dose adjustment recommended, but monitor for increased toxicity (e.g., cardiotoxicity, myelosuppression) due to age-related organ function decline.
Myocardial toxicity (including delayed congestive heart failure) may occur with cumulative doses >550 mg/m²; less if prior mediastinal irradiation. Extravasation causes severe tissue necrosis. Secondary acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) reported. Hepatic impairment requires dose adjustment. Use during pregnancy only if benefit outweighs risk.
Cardiotoxicity: risk of myocardial damage, including acute left ventricular failure. Myelosuppression: severe, dose-limiting. Hepatic impairment: requires dose reduction. Infusion reactions: may be severe or life-threatening. Must be administered by physician experienced in cancer chemotherapy.
Cardiotoxicity (cumulative dose-dependent, enhanced by prior chest irradiation, age >70, pre-existing cardiac disease); myelosuppression; extravasation injury; secondary malignancies; tumor lysis syndrome; hepatic impairment; radiation recall; mutagenic and carcinogenic potential; impairment of fertility.
Cardiotoxicity (cumulative dose-dependent, monitor LVEF), myelosuppression (neutropenia, thrombocytopenia), infusion reactions (premedicate), hand-foot syndrome (palmar-plantar erythrodysesthesia), secondary malignancies, extravasation necrosis, hepatic impairment (dose adjustment), immunosuppression, embryo-fetal toxicity.
Hypersensitivity to doxorubicin or any component; severe hepatic impairment; severe myelosuppression; baseline cardiac dysfunction; previous treatment with maximum cumulative doses of doxorubicin or other anthracyclines.
Absolute: history of hypersensitivity to doxorubicin or other anthracyclines. Relative: severe hepatic impairment, severe myelosuppression, pre-existing cardiomyopathy, prior treatment with maximum cumulative doses of anthracyclines (e.g., doxorubicin >550 mg/m², liposomal doxorubicin >900 mg/m²).
Grapefruit and grapefruit juice should be avoided as they may inhibit CYP3A4 metabolism and increase doxorubicin toxicity. No other significant food interactions; maintain adequate hydration and nutrition.
No specific food interactions reported. Avoid grapefruit juice per general chemotherapy precautions. Maintain adequate oral hygiene; avoid spicy or acidic foods during mucositis.
FDA Pregnancy Category D. First trimester: high risk of major congenital malformations (e.g., CNS, cardiovascular) and spontaneous abortion. Second and third trimesters: risk of fetal growth restriction, oligohydramnios, and neonatal myelosuppression. Avoid use unless maternal benefit outweighs fetal risk.
Doxorubicin hydrochloride liposome injection (DOXIL) is classified as Pregnancy Category D. There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans. Potential benefits may warrant use of the drug in pregnant women despite potential risks. First trimester: High risk of teratogenicity including major malformations (e.g., cardiovascular, neural tube defects). Second and third trimesters: Risk of fetal growth restriction, oligohydramnios, and neonatal myelosuppression. Use only if clearly needed and no safer alternative.
Not recommended. Doxorubicin is excreted into human breast milk; M/P ratio not available. Potential for serious adverse reactions in nursing infants (e.g., immunosuppression, neutropenia). Discontinue breastfeeding during treatment and for at least 10 days after last dose.
Doxorubicin is excreted in human milk. The milk-to-plasma (M/P) ratio for doxorubicin is approximately 0.5 to 2.0 based on limited data. Because of the potential for serious adverse reactions in nursing infants from doxorubicin (e.g., myelosuppression, cardiotoxicity), discontinue breastfeeding during and for at least 3 months after the last dose of DOXIL.
No established dose adjustments in pregnancy. Pharmacokinetic changes (increased plasma volume, altered protein binding) may require monitoring for toxicity or efficacy. Use lowest effective dose; consider dose reduction for myelosuppression or cardiotoxicity. Administration frequency may be modified based on gestational age and maternal tolerance.
Pharmacokinetic data in pregnancy are limited; however, physiological changes (e.g., increased plasma volume, hepatic clearance) may alter doxorubicin exposure. No specific dose adjustment guidelines exist. Use the standard dose based on body surface area (BSA) while closely monitoring for toxicity. Consider dose reduction if severe myelosuppression or hepatic impairment occurs. Avoid use in the first trimester if possible.
Pre-medicate with antiemetics (e.g., 5-HT3 antagonist) prior to administration. Monitor left ventricular ejection fraction (LVEF) at baseline and periodically due to cumulative dose-related cardiotoxicity (lifetime max 450-550 mg/m2, lower with prior chest radiation). Extravasation causes severe tissue necrosis; administer through a free-flowing IV line. Reduce dose in hepatic impairment (bilirubin >1.2 mg/d L). Observe for urine discoloration (red) for 1-2 days post-infusion. Avoid concurrent use with trastuzumab or other cardiotoxic agents.
Monitor for infusion reactions; premedicate with dexamethasone and antihistamines. Palmar-plantar erythrodysesthesia (hand-foot syndrome) may require dose delay/reduction. Cumulative dose >550 mg/m² increases cardiotoxicity risk. Do not substitute with non-liposomal doxorubicin.
