Lipodox 50
Lipodox 50 Uses, Dosage, Side Effects, Food Interaction and all others data.
Lipodox 50 is a cytotoxic anthracycline antibiotic. The cytotoxic action results from its binding to DNA and inhibition of nucleic acid synthesis. Lipodox 50 has been shown to produce regression in a variety of disseminated malignancies.
Lipodox 50 is an antineoplastic in the anthracycline class. General properties of drugs in this class include: interaction with DNA in a variety of different ways including intercalation (squeezing between the base pairs), DNA strand breakage and inhibition with the enzyme topoisomerase II. Most of these compounds have been isolated from natural sources and antibiotics. However, they lack the specificity of the antimicrobial antibiotics and thus produce significant toxicity. The anthracyclines are among the most important antitumor drugs available. Lipodox 50 is widely used for the treatment of several solid tumors while daunorubicin and idarubicin are used exclusively for the treatment of leukemia. Lipodox 50 may also inhibit polymerase activity, affect regulation of gene expression, and produce free radical damage to DNA. Lipodox 50 possesses an antitumor effect against a wide spectrum of tumors, either grafted or spontaneous. The anthracyclines are cell cycle-nonspecific.

- Multiple Myeloma: In combination with bortezomib in patients who have not previously received bortezomib and have received at least one prior therapy.
Lipodox 50 is also used to associated treatment for these conditions: Acute Lymphoblastic Leukaemias (ALL), Acute Myeloblastic Leukemia, Advanced Endometrial Cancer, Advanced Soft Tissue Sarcoma, Bladder transitional cell carcinoma, Carcinoma, Bronchogenic, Gastric Carcinoma, Kaposi's Sarcoma AIDS Related, Lymphoma, Hodgkins, Malignant Lymphomas, Metastatic Breast Cancer, Multiple Myeloma (MM), Mycosis Fungoides (MF), Neuroblastomas, Ovarian Cancer Metastatic, Ovarian Carcinoma, Sarcoma, Bone, Sezary Syndrome, Soft Tissue Sarcoma (STS), Thyroid Carcinoma, Waldenström's Macroglobulinemia (WM), Wilms' tumor, Advanced Thymoma, Advanced uterine sarcoma
How Lipodox 50 works
Lipodox 50 has antimitotic and cytotoxic activity through a number of proposed mechanisms of action: Lipodox 50 forms complexes with DNA by intercalation between base pairs, and it inhibits topoisomerase II activity by stabilizing the DNA-topoisomerase II complex, preventing the religation portion of the ligation-religation reaction that topoisomerase II catalyzes.
Dosage
Lipodox 50 dosage
Administer Lipodox 50 at an initial rate of 1 mg/min to minimize the risk of infusion reactions. If no infusion related reactions occur, increase rate of infusion to complete administration over 1 hour. Do not administer as bolus injection or undiluted solution.
- Ovarian cancer: 50 mg/m2 IV every 4 weeks
- AIDS-related Kaposi’s Sarcoma: 20 mg/m2 IV every 3 weeks
- Multiple Myeloma: 30 mg/m2 IV on day 4 following bortezomib
Side Effects
Leucopenia, thrombocytopenia, nausea, vomiting, diarrhoea. Rarely facial flushing, rash, alopecia. Blurred vision, headache, seizures, paraesthesia, confusion, malaise, lethargy, skin pigmentation.
Toxicity
LD50=21800 ug/kg (rat, subcutaneous)
Precaution
Elderly, children, hepatic impairment. Monitor blood counts and ECG.
Interaction
Lipodox 50 interacts with a number of other drugs e.g. antibiotics (aminoglycosides), steroids, aminophylline and propranolol.
Food Interaction
- Avoid St. John's Wort. This herb induces CYP3A4 metabolism, which may reduce the serum concentration of doxorubicin.
- Exercise caution with grapefruit products. Grapefruit inhibits CYP3A4 metabolism, which may increase the serum concentration of doxorubicin.
Lipodox 50 Drug Interaction

Lipodox 50 Disease Interaction
Major: infections, cardiomyopathy, hepatic dysfunction, myelosuppression
Volume of Distribution
The distributive half-life is 5 minutes, which suggests that doxorubicin is rapidly taken up by tissue. Steady state volume of distribution = 809 to 1214 L/m2
Half Life
Terminal half life = 20 - 48 hours.
Clearance
- 324-809 mL/min/m2 [by metabolism and biliary excretion]
- 1088 mL/min/m2 [Men]
- 433 mL/min/m2 [Women]
- 1540 mL/min/m2 [children greater than 2 years of age receiving administration of 10 to 75 mg/m2 doses]
- 813 mL/min/m2 [infants younger than 2 years of age receiving administration of 10 to 75 mg/m2 doses]
Elimination Route
40% of the dose appears in bile in 5 days. 5-12% of the drug and its metabolites appears in urine during the same time period. <3% of the dose recovered in urine was doxorubicinol.
Pregnancy & Breastfeeding use
Category D: There is positive evidence of human foetal risk, but the benefits from use in pregnant women may be acceptable despite the risk (e.g., if the drug is needed in a life-threatening situation or for a serious disease for which safer drugs cannot be used or are ineffective).
Contraindication
Cardiac disease, neonates, pregnancy and lactation, prior irradiation to mediastinum. IM/SC admin. Severe myelosuppression due to previous treatment with antitumour agents or radiotherapy.
Special Warning
Hepatic Impairment-
serum-bilirubin: 12-30 mcg/ml: Half the normal dose;
serum-bilirubin: >30 mcg/ml: Quarter of the usual dose.
Acute Overdose
Acute overdosage may increase the toxic effects of mucositis, leukopenia and thrombocytopenia. Treatment includes hospitalisation of the severely myelosuppressed patient, antimicrobials, platelet transfusions and symptomatic treatment of mucositis. Use of haemopoietic growth factor (G-CSF, GM-CSF) may be considered. Cumulative dosage increases risk of cardiomyopathy and resultant congestive heart failure which may be managed with digitalis preparations, diuretics, and after load reducers such as ACE inhibitors.
Storage Condition
Powder for injection: Store at 15-30°C.
Solution for injection & liposomal formulations: Refrigerate at 2-8°C. Do not freeze.
