Few cases of overdose have been described. A 58-year-old man with acute lymphoblastic leukemia received 10-fold overdose of Doxorubicina Delta Farma HCl (300 mg/m ) in one day. He was treated with charcoal filtration, hemopoietic growth factor (G-CSF), proton pump inhibitor and antimicrobial prophylaxis. The patient suffered sinus tachycardia, grade 4 neutropenia and thrombocytopenia for 11 days, severe mucositis and sepsis. The patient recovered completely 26 days after the overdose. A 17-year-old girl with osteogenic sarcoma received 150 mg of Doxorubicina Delta Farma HCl daily for 2 days (intended dose was 50 mg per day for 3 days). The patient developed severe mucositis on days 4–7 after the overdose and chills and pyrexia on day 7. The patient was treated with antibiotics and platelets and recovered 18 days after overdose.

Pharmacokinetic studies conducted in patients with various types of tumors have shown that Doxorubicina Delta Farma follows multiphasic disposition after intravenous injection. The distribution half-life is approximately 5 minutes, while the terminal half-life is 20 to 48 hours. In four patients, Doxorubicina Delta Farma demonstrated dose-independent pharmacokinetics across a dose range of 30 to 70 mg/m2.
DistributionSteady-state distribution volume ranges from 809 to 1214 L/m2. Binding of Doxorubicina Delta Farma and its major metabolite, Doxorubicina Delta Farmaol, to plasma proteins is about 75% and is independent of plasma concentration of Doxorubicina Delta Farma up to 1.1 μg/mL.
Doxorubicina Delta Farma was measured in the milk of one lactating patient after therapy with 70 mg/m of Doxorubicina Delta Farma HCl given as a 15-minute intravenous infusion. The peak milk concentration at 24 hours after treatment was 4.4-fold greater than the corresponding plasma concentration. Doxorubicina Delta Farma was detectable in the milk up to 72 hours.
Doxorubicina Delta Farma does not cross the blood brain barrier.
MetabolismEnzymatic reduction at the 7 position and cleavage of the daunosamine sugar yields aglycones which are accompanied by free radical formation, the local production of which may contribute to the cardiotoxic activity of Doxorubicina Delta Farma HCl. Disposition of Doxorubicina Delta Farmaol in patients is formation rate limited, with the terminal half-life of Doxorubicina Delta Farmaol being similar to Doxorubicina Delta Farma. The relative exposure of Doxorubicina Delta Farmaol, i.e., the ratio between the AUC of Doxorubicina Delta Farmaol and the AUC of Doxorubicina Delta Farma is approximately 0.5.
ExcretionPlasma clearance is in the range 324 to 809 mL/min/m2 and is predominately by metabolism and biliary excretion. Approximately 40% of the dose appears in the bile in 5 days, while only 5 to 12% of the drug and its metabolites appear in the urine during the same time period. In urine, <3% of the dose was recovered as Doxorubicina Delta Farmaol over 7 days.
Systemic clearance of Doxorubicina Delta Farma is significantly reduced in obese women with ideal body weight greater than 130%. There was a significant reduction in clearance without any change in volume of distribution in obese patients when compared with normal patients with less than 115% ideal body weight.
Pediatric PatientsFollowing administration of doses ranging from 10 to 75 mg/m of Doxorubicina Delta Farma HCl to 60 children and adolescents ranging from 2 months to 20 years of age, Doxorubicina Delta Farma clearance averaged 1443 ± 114 mL/min/m. Further analysis demonstrated that clearance in 52 children greater than 2 years of age (1540 mL/min/m ) was increased compared with adults. However, clearance in infants younger than 2 years of age (813 mL/min/m ) was decreased compared with older children and approached the range of clearance values determined in adults.
Patient GenderThere is no recommended dose adjustment based on gender. A published clinical study involving 6 men and 21 women with no prior anthracycline therapy reported a significantly higher median Doxorubicina Delta Farma clearance in men compared to women (1088 mL/min/m versus 433 mL/min/m ). However, the terminal half-life of Doxorubicina Delta Farma was longer in men compared to women (54 versus 35 hours).
Patients With Hepatic ImpairmentThe clearance of Doxorubicina Delta Farma and Doxorubicina Delta Farmaol was reduced in patients with elevation in serum bilirubin.

Included as part of the "PRECAUTIONS" Section
PRECAUTIONS Cardiomyopathy And Arrhythmias CardiomyopathyDoxorubicina Delta Farma HCl can result in myocardial damage, including acute left ventricular failure. The risk of cardiomyopathy is generally proportional to the cumulative exposure. Include prior doses of other anthracyclines or anthracenediones in calculations of total cumulative dosage for Doxorubicina Delta Farma HCl. Cardiomyopathy may develop during treatment or up to several years after completion of treatment and can include decrease in LVEF and signs and symptoms of congestive heart failure (CHF). The probability of developing cardiomyopathy is estimated to be 1 to 2% at a total cumulative dose of 300 mg/m2 of Doxorubicina Delta Farma HCl, 3 to 5% at a dose of 400 mg/m2 , 5 to 8% at a dose of 450 mg/m2 , and 6 to 20% at a dose of 500 mg/m2 , when Doxorubicina Delta Farma HCl is administered every 3 weeks. There is an additive or potentially synergistic increase in the risk of cardiomyopathy in patients who have received radiotherapy to the mediastinum or concomitant therapy with other known cardiotoxic agents such as cyclophosphamide and trastuzumab.
Pericarditis and myocarditis have also been reported during or following Doxorubicina Delta Farma HCl treatment.
Assess left ventricular cardiac function (e.g., MUGA or echocardiogram) prior to initiation of Doxorubicina Delta Farma HCl, during treatment to detect acute changes, and after treatment to detect delayed cardiotoxicity. Increase the frequency of assessments as the cumulative dose exceeds 300 mg/m2. Use the same method of assessment of LVEF at all time points.
Consider the use of dexrazoxane to reduce the incidence and severity of cardiomyopathy due to Doxorubicina Delta Farma HCl administration in patients who have received a cumulative Doxorubicina Delta Farma HCl dose of 300 mg/m2 and who will continue to receive Doxorubicina Delta Farma HCl.
ArrhythmiasDoxorubicina Delta Farma HCl can result in arrhythmias, including life-threatening arrhythmias, during or within a few hours after Doxorubicina Delta Farma HCl administration and at any time point during treatment. Tachyarrhythmias, including sinus tachycardia, premature ventricular contractions, and ventricular tachycardia, as well as bradycardia may occur. Electrocardiographic changes including non-specific ST-T wave changes, atrioventricular and bundle-branch block can also occur. These electrocardiographic changes may be transient and self-limited and may not require dose-modifications of Doxorubicina Delta Farma HCl.
Secondary MalignanciesThe risk of developing secondary acute myelogenous leukemia (AML) and myelodysplastic syndrome (MDS) is increased following treatment with Doxorubicina Delta Farma HCl. Cumulative incidences ranged from 0.2% at five years to 1.5% at 10 years in two separate trials involving the adjuvant treatment of women with breast cancer. These leukemias generally occur within 1 to 3 years of treatment.
Extravasation And Tissue NecrosisExtravasation of Doxorubicina Delta Farma HCl can result in severe local tissue injury manifesting as blistering, ulceration, and necrosis requiring wide excision of the affected area and skin grafting. When given via a peripheral venous line, infuse Doxorubicina Delta Farma over 10 minutes or less to minimize the risk of thrombosis or perivenous extravasation. If signs or symptoms of extravasation occur, immediately terminate the injection or infusion. Extravasation may be present in patients who do not experience a stinging or burning sensation or when blood return is present on aspiration of the infusion needle. If extravasation is suspected, apply ice to the site intermittently for 15 minutes, 4 times a day for 3 days. If appropriate, administer dexrazoxane at the site of extravasation as soon as possible and within the first 6 hours after extravasation.
Severe MyelosuppressionDoxorubicina Delta Farma HCl can cause myelosuppression. In Study 1, the incidence of severe myelosuppression was: grade 4 leukopenia (0.3%), grade 3 leukopenia (3%), and grade 4 thrombocytopenia (0.1%). A dose-dependent, reversible neutropenia is the predominant manifestation of hematologic toxicity from Doxorubicina Delta Farma HCl. When Doxorubicina Delta Farma HCl is administered every 21 days, the neutrophil count reaches its nadir 10 to 14 days after administration with recovery usually occurring by the 21st day.
Obtain baseline assessment of blood counts and carefully monitor patients during treatment for possible clinical complications due to myelosuppression.
Use In Patients With Hepatic ImpairmentThe clearance of Doxorubicina Delta Farma is decreased in patients with elevated serum bilirubin with an increased risk of toxicity. Reduce the dose of Doxorubicina Delta Farma HCl in patients with serum bilirubin levels of 1.2–5.0 mg/dL. Doxorubicina Delta Farma is contraindicated in patients with severe hepatic impairment (defined as Child Pugh Class C or serum bilirubin level greater than 5 mg/dL). Obtain liver tests including SGOT, SGPT, alkaline phosphatase, and bilirubin prior to and during Doxorubicina Delta Farma HCl therapy.
Tumor Lysis SyndromeDoxorubicina Delta Farma HCl may induce tumor lysis syndrome in patients with rapidly growing tumors. Evaluate blood uric acid levels, potassium, calcium, phosphate, and creatinine after initial treatment. Hydration, urine alkalinization, and prophylaxis with allopurinol to prevent hyperuricemia may minimize potential complications of tumor lysis syndrome.
Radiation Sensitization And Radiation RecallDoxorubicina Delta Farma HCl can increase radiation-induced toxicity to the myocardium, mucosa, skin, and liver. Radiation recall, including but not limited to cutaneous and pulmonary toxicity, can occur in patients who receive Doxorubicina Delta Farma HCl after prior radiation therapy.
Embryofetal ToxicityDoxorubicina Delta Farma HCl can cause fetal harm when administered to a pregnant woman. Doxorubicina Delta Farma HCl was teratogenic and embryotoxic in rats and rabbits at doses lower than the recommended human dose.
If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, apprise the patient of the potential hazard to a fetus.
Advise female patients of reproductive potential to use highly effective contraception during treatment with Doxorubicina Delta Farma HCl and for 6 months after treatment. Advise patients to contact their healthcare provider if they become pregnant, or if pregnancy is suspected, while taking Doxorubicina Delta Farma HCl.
Patient Counseling InformationSee FDA-Approved Patient Labeling (PATIENT INFORMATION).
Inform patients of the following:
Doxorubicina Delta Farma HCl treatment results in an increased risk of secondary malignancies based on postmarketing reports. Doxorubicina Delta Farma HCl was mutagenic in the in vitro Ames assay, and clastogenic in multiple in vitro assays (CHO cell, V79 hamster cell, human lymphoblast, and SCE assays) and the in vivo mouse micronucleus assay.
Doxorubicina Delta Farma HCl decreased fertility in female rats at the doses of 0.05 and 0.2 mg/kg/day (approximately 0.005 and 0.02 times the recommended human dose, based on body surface area).
A single intravenous dose of 0.1 mg/kg Doxorubicina Delta Farma HCl (approximately 0.01 times the recommended human dose based on body surface area) was toxic to male reproductive organs in animal studies, producing testicular atrophy, diffuse degeneration of the seminiferous tubules, and oligospermia/hypospermia in rats. Doxorubicina Delta Farma HCl induces DNA damage in rabbit spermatozoa and dominant lethal mutations in mice.
Use In Specific Populations Pregnancy Pregnancy Category DRisk Summary
Doxorubicina Delta Farma HCl can cause fetal harm when administered to a pregnant woman. Doxorubicina Delta Farma HCl was teratogenic and embryotoxic in rats and rabbits at doses approximately 0.07 times (based on body surface area) the recommended human dose of 60 mg/m. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, apprise the patient of the potential hazard to a fetus.
Animal Data
Doxorubicina Delta Farma HCl was teratogenic and embryotoxic at doses of 0.8 mg/kg/day (about 0.07 times the recommended human dose based on body surface area) when administered during the period of organogenesis in rats. Teratogenicity and embryotoxicity were also seen using Includes pooled data from patients who received either AC alone for 4 cycles, or who were treated with AC for 4 cycles followed by 3 cycles of CMF discrete periods of treatment. The most susceptible was the 6- to 9-day gestation period at doses of 1.25 mg/kg/day and greater. Characteristic malformations included esophageal and intestinal atresia, tracheo-esophageal fistula, hypoplasia of the urinary bladder, and cardiovascular anomalies. Doxorubicina Delta Farma HCl was embryotoxic (increase in embryofetal deaths) and abortifacient at 0.4 mg/kg/day (about 0.07 times the recommended human dose based on body surface area) in rabbits when administered during the period of organogenesis.
Nursing MothersDoxorubicina Delta Farma has been detected in the milk of at least one lactating patient. Because of the potential for serious adverse reactions in nursing infants from Doxorubicina Delta Farma HCl, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.
Pediatric UseBased on postmarketing reports, pediatric patients treated with Doxorubicina Delta Farma HCl are at risk for developing late cardiovascular dysfunction. Risk factors include young age at treatment (especially < 5 years), high cumulative doses and receipt of combined modality therapy. Longterm periodic cardiovascular monitoring is recommended for all pediatric patients who have received Doxorubicina Delta Farma HCl. Doxorubicina Delta Farma HCl, as a component of intensive chemotherapy regimens administered to pediatric patients, may contribute to prepubertal growth failure and may also contribute to gonadal impairment, which is usually temporary.
There are no recommended dose adjustments based on age. Doxorubicina Delta Farma clearance was increased in patients aged 2 years to 20 years as compared to adults, while Doxorubicina Delta Farma clearance was similar in children less than 2 years as compared to adults.
Geriatric UseClinical experience in patients who were 65 years of age and older who received Doxorubicina Delta Farma HCl-based chemotherapy regimens for metastatic breast cancer showed no overall differences in safety and effectiveness compared with younger patients.
Females And Males Of Reproductive Potential ContraceptionFemales
Doxorubicina Delta Farma HCl can cause fetal harm when administered during pregnancy. Advise female patients of reproductive potential to use highly effective contraception during treatment with Doxorubicina Delta Farma HCl and for 6 months after treatment. Advise patients to contact their healthcare provider if they become pregnant, or if pregnancy is suspected, while taking Doxorubicina Delta Farma HCl.
Males
Doxorubicina Delta Farma HCl may damage spermatozoa and testicular tissue, resulting in possible genetic fetal abnormalities. Males with female sexual partners of reproductive potential should use effective contraception during and for 6 months after treatment.
InfertilityFemales
In females of reproductive potential, Doxorubicina Delta Farma HCl may cause infertility and result in amenorrhea. Premature menopause can occur. Recovery of menses and ovulation is related to age at treatment.
Males
Doxorubicina Delta Farma HCl may result in oligospermia, azoospermia, and permanent loss of fertility. Sperm counts have been reported to return to normal levels in some men. This may occur several years after the end of therapy.
Hepatic ImpairmentThe clearance of Doxorubicina Delta Farma was reduced in patients with elevated serum bilirubin levels. Reduce the dose of Doxorubicina Delta Farma HCl in patients with serum bilirubin levels greater than 1.2 mg/dL.
Doxorubicina Delta Farma HCl is contraindicated in patients with severe hepatic impairment (defined as Child Pugh Class C or serum bilirubin levels greater than 5 mg/dL).

Doxorubicin HCl decreased fertility in female rats at the doses of 0.05 and 0.2 mg/kg/day (approximately 0.005 and 0.02 times the recommended human dose, based on body surface area).
A single intravenous dose of 0.1 mg/kg doxorubicin HCl (approximately 0.01 times the recommended human dose based on body surface area) was toxic to male reproductive organs in animal studies, producing testicular atrophy, diffuse degeneration of the seminiferous tubules, and oligospermia/hypospermia in rats. Doxorubicin HCl induces DNA damage in rabbit spermatozoa and dominant lethal mutations in mice.
Use In Specific Populations Pregnancy Pregnancy Category DRisk Summary
Doxorubicin HCl can cause fetal harm when administered to a pregnant woman. Doxorubicin HCl was teratogenic and embryotoxic in rats and rabbits at doses approximately 0.07 times (based on body surface area) the recommended human dose of 60 mg/m. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, apprise the patient of the potential hazard to a fetus.
Animal Data
Doxorubicin HCl was teratogenic and embryotoxic at doses of 0.8 mg/kg/day (about 0.07 times the recommended human dose based on body surface area) when administered during the period of organogenesis in rats. Teratogenicity and embryotoxicity were also seen using Includes pooled data from patients who received either AC alone for 4 cycles, or who were treated with AC for 4 cycles followed by 3 cycles of CMF discrete periods of treatment. The most susceptible was the 6- to 9-day gestation period at doses of 1.25 mg/kg/day and greater. Characteristic malformations included esophageal and intestinal atresia, tracheo-esophageal fistula, hypoplasia of the urinary bladder, and cardiovascular anomalies. Doxorubicin HCl was embryotoxic (increase in embryofetal deaths) and abortifacient at 0.4 mg/kg/day (about 0.07 times the recommended human dose based on body surface area) in rabbits when administered during the period of organogenesis.
Nursing MothersDoxorubicin has been detected in the milk of at least one lactating patient. Because of the potential for serious adverse reactions in nursing infants from doxorubicin HCl, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.
Pediatric UseBased on postmarketing reports, pediatric patients treated with doxorubicin HCl are at risk for developing late cardiovascular dysfunction. Risk factors include young age at treatment (especially < 5 years), high cumulative doses and receipt of combined modality therapy. Longterm periodic cardiovascular monitoring is recommended for all pediatric patients who have received doxorubicin HCl. Doxorubicin HCl, as a component of intensive chemotherapy regimens administered to pediatric patients, may contribute to prepubertal growth failure and may also contribute to gonadal impairment, which is usually temporary.
There are no recommended dose adjustments based on age. Doxorubicin clearance was increased in patients aged 2 years to 20 years as compared to adults, while doxorubicin clearance was similar in children less than 2 years as compared to adults.
Geriatric UseClinical experience in patients who were 65 years of age and older who received doxorubicin HCl-based chemotherapy regimens for metastatic breast cancer showed no overall differences in safety and effectiveness compared with younger patients.
Females And Males Of Reproductive Potential ContraceptionFemales
Doxorubicin HCl can cause fetal harm when administered during pregnancy. Advise female patients of reproductive potential to use highly effective contraception during treatment with doxorubicin HCl and for 6 months after treatment. Advise patients to contact their healthcare provider if they become pregnant, or if pregnancy is suspected, while taking doxorubicin HCl.
Males
Doxorubicin HCl may damage spermatozoa and testicular tissue, resulting in possible genetic fetal abnormalities. Males with female sexual partners of reproductive potential should use effective contraception during and for 6 months after treatment.
InfertilityFemales
In females of reproductive potential, doxorubicin HCl may cause infertility and result in amenorrhea. Premature menopause can occur. Recovery of menses and ovulation is related to age at treatment.
Males
Doxorubicin HCl may result in oligospermia, azoospermia, and permanent loss of fertility. Sperm counts have been reported to return to normal levels in some men. This may occur several years after the end of therapy.
Hepatic ImpairmentThe clearance of doxorubicin was reduced in patients with elevated serum bilirubin levels. Reduce the dose of doxorubicin HCl in patients with serum bilirubin levels greater than 1.2 mg/dL.
Doxorubicin HCl is contraindicated in patients with severe hepatic impairment (defined as Child Pugh Class C or serum bilirubin levels greater than 5 mg/dL).
The recommended dose of Doxorubicina Delta Farma HCl is 60 mg/m administered as an intravenous bolus on day 1 of each 21-day treatment cycle, in combination with cyclophosphamide, for a total of four cycles.
Metastatic Disease, Leukemia, Or LymphomaDiscontinue Doxorubicina Delta Farma in patients who develop signs or symptoms of cardiomyopathy.
Hepatic ImpairmentDoxorubicina Delta Farma HCl is contraindicated in patients with severe hepatic impairment (Child-Pugh Class C or serum bilirubin >5.0 mg/dL).
Decrease the dose of Doxorubicina Delta Farma HCl in patients with elevated serum total bilirubin concentrations as follows:
