doxorubicin hydrochloride, liposomal
Pharmacologic class: Anthracycline
Therapeutic class: Antibiotic antineoplastic
Pregnancy risk category D
FDA Box Warning
• Drug may cause cardiotoxicity. Myocardial damage may lead to heart failure and may occur as total cumulative dose (which includes previous use of other anthracyclines or anthracenediones) approaches 550 mg/m2. Toxicity may occur at lower cumulative doses in patients who have had previous mediastinal irradiation or are receiving concurrent cyclophosphamides.
• Acute infusion-related reactions occur in up to 10% of patients. They usually resolve over several hours to 1 day after infusion ends; in some patients, they resolve with slower infusion rate. Serious and sometimes life-threatening allergic or anaphylactoid-like infusion reactions may occur. Keep emergency equipment and drugs to treat reaction available for immediate use.
• Drug may cause severe myelosuppression.
• Reduce dosage in hepatic impairment.
• Accidental substitution of liposomal form for doxorubicin hydrochloride may cause severe adverse effects. Don't substitute on mg-per-mg basis.
Unclear. Thought to inhibit DNA and RNA synthesis by forming complex with DNA. Also exerts immunosuppressive activity. Liposomal encapsulation increases uptake by tumors, prolongs drug action, and may decrease toxicity. Cell-cycle-S-phase specific.

Route/DosageOther regimens are used
Availability (generic available)
- Monitor BP, pulse, respiratory rate, and temperature frequently during administration. Report significant changes.
- Monitor for acute infusion-related reactions consisting of flushing, shortness of breath, facial swelling, headache, chills, chest pain, back pain, chest or throat tightness, fever, tachycardia, pruritus, rash, cyanosis, syncope, bronchospasm, asthma, apnea, which may be accompanied by hypotension. Reactions usually resolve over 1 day and are usually limited to first dose. Slowing infusion rate may minimize this reaction. Reaction is thought to be due to liposome.
- Observe for signs and symptoms of anaphylaxis (rash, pruritus, laryngeal edema, wheezing). Discontinue doxorubicin liposome and notify health care professional immediately if these problems occur. Keep epinephrine, an antihistamine, and resuscitation equipment close by in case of an anaphylactic reaction.
- Monitor for bone marrow depression. Assess for bleeding (bleeding gums, bruising, petechiae, guaiac stools, urine, and emesis) and avoid IM injections and taking rectal temperatures if platelet count is low. Apply pressure to venipuncture sites for 10 min. Assess for signs of infection during neutropenia. Anemia may occur. Monitor for increased fatigue, dyspnea, and orthostatic hypotension.
- Monitor intake and output ratios, and report occurrence of significant discrepancies. Encourage fluid intake of 2000–3000 mL/day. Allopurinol and alkalinization of the urine may be used to decrease serum uric acid levels and to help prevent urate stone formation.
- Severe and protracted nausea and vomiting may occur as early as 1 hr after therapy and may last 24 hr. Administer parenteral antiemetics 30–45 min prior to therapy and routinely around the clock for the next 24 hr as indicated. Monitor amount of emesis and notify health care professional if emesis exceeds guidelines to prevent dehydration.
- Monitor for development of signs of cardiac toxicity, which may be either acute and transient (ST segment depression, flattened T wave, sinus tachycardia, and extrasystoles) or late onset (usually occurs 1–6 mo after initiation of therapy) and characterized by intractable HF (peripheral edema, dyspnea, rales/crackles, weight gain); occurs more frequently in patients receiving a cumulative dose of ≥550 mg/m2. Chest x ray, echocardiography, ECGs, and radionuclide angiography may be ordered prior to and periodically during therapy. Cardiotoxicity is more prevalent in children younger than 2 yr and geriatric patients. Dexrazoxane may be used to prevent cardiotoxicity in patients receiving cumulative doses of >300 mg/m2.
- Assess injection site frequently for redness, irritation, or inflammation. Doxorubicin liposome is an irritant but may infiltrate painlessly even if blood returns on aspiration of infusion needle. Severe tissue damage may occur if doxorubicin liposome extravasates. If extravasation occurs, stop infusion immediately, restart, and complete dose in another vein. If possible, withdraw 3–5 mL of blood to remove doxorubicin liposome. Local infiltration of antidote is not recommended. Delineate the infiltrated area on patient's skin with a felt-tip marker. Elevate for 48 hr above heart level using a sling or stockinette dressing with an observation window cut in the dressing. Avoid pressure or friction. Do not rub the area. Observe for signs of increased erythema, pain, or skin necrosis. If increased symptoms occur, consult a plastic surgeon. After 48 hr, encourage patient to use extremity normally to promote full range of motion.
- Assess oral mucosa frequently for development of stomatitis. Increased dosing interval and/or decreased dose is recommended if lesions are painful or interfere with nutrition.
- Continue to assess oral mucosa regularly during and for at least 6 yr for ulceration or any discomfort; may indicate secondary oral cancer.
- Monitor for skin toxicity with prolonged use; palmar-plantar erythrodysesthesia usually occurs after 6 wk of treatment and consists of swelling, pain, and erythema of the hands and feet. This may progress to desquamation but usually regresses after 2 wk. In severe cases, modification and delay of future doses of doxorubicin liposome may be necessary.
- Lab Test Considerations: Monitor CBC and differential prior to and periodically during therapy. The WBC nadir occurs 10–14 days after administration, and recovery usually occurs by the 21st day. Thrombocytopenia and anemia may also occur. ↑ dosing interval and/or ↓ dose is recommended if ANC is <1000 cells/mm3 and/or platelet count is <50,000 cells/mm3. If ANC 1500 – 1900 cells/mm3 and platelets 75,000–150,000 cells/mm3 (Grade 1), resume treatment with no dose reduction. If ANC 1000 – <1500 cells/mm3and platelets 50,000 – <75,000 cells/mm3 (Grade 2), wait until ANC >1500 and platelets >75,000; then redose with no dose reduction. If ANC 500 – 999 cells/mm3and platelets 25,000 – <50,000 cells/mm3 (Grade 3), wait until ANC >1500 and platelets >75,000; then redose with no dose reduction. If ANC <500 and platelets <25,000 cells/mm3 (Grade 4), wait until ANC >1500 and platelets >75,000, then redose at 25% dose reduction or continue full dose with cytokine support.
- Monitor renal (BUN and creatinine) and hepatic (AST, ALT, LDH, and serum bilirubin) function prior to and periodically during therapy. Dose reduction is required for bilirubin >1.2 m g/dL or serum creatinine >3 m g/dL.
- May cause ↑ serum and urine uric acid concentrations.
Potential Nursing DiagnosesRisk for infection (Adverse Reactions)
Decreased cardiac output (Adverse Reactions)
- high alert: Fatalities have occurred with incorrect administration of chemotherapeutic agents. Before administering, clarify all ambiguous orders; double-check single, daily, and course-of-therapy dose limits; have second practitioner independently double-check original order, calculations, and infusion pump settings.
- high alert: Do not confuse doxorubicin hydrochloride liposome (Doxil) with doxorubicin hydrochloride (Adriamycin, Rubex) or with daunorubicin hydrochloride (Cerubidine). Do not confuse Doxil with Paxil. Clarify orders that do not include generic and brand names.
- Prepare solution in a biologic cabinet. Wear gloves, gown, and mask while handling medication. Discard IV equipment in specially designated containers.
- Aluminum needles may be used to administer doxorubicin but should not be used during storage, because prolonged contact results in discoloration of solution and formation of a dark precipitate. Solution is red.
- Intermittent Infusion: Diluent: Dilute dose, up to 90 mg, in 250 mL and doses >90 mg in 500 mL of D5W. Do not dilute with other diluents or diluents containing a bacteriostatic agent. Solution is not clear, but a translucent red liposomal dispersion. Do not use in-line filters. Refrigerate diluted solutions and administer within 24 hr of dilution.
- Rate: Initial rate of infusion should be 1 mg/min to minimize risk of infusion reactions. If no reactions occur, increase rate to complete administration within 1 hr. Do not administer as a bolus or undiluted solution. Rapid infusion may increase infusion-related reactions.
