1. WHAT DOXORUBICIN 2 MG/ML IS AND WHAT IT IS USED FOR

Doxorubicin, the active ingredient in Doxorubicin 2 mg/ml, is a medicine that kills cancer cells. It is used to treat several types of cancer, e.g., breast cancer, lung cancer, leukaemia (cancer of the blood or bone marrow), tumours of the thyroid gland, bladder and ovaries, and paediatric malignancy. Doxorubicin 2 mg/ml is frequently used in combination with other anti-cancer treatments.

2. BEFORE YOU USE DOXORUBICIN 2 MG/ML
Do not use Doxorubicin 2 mg/ml
  • if you are hypersensitive (allergic) to doxorubicin or any of the other ingredients of Doxorubicin 2 mg/ml, or to other anthracyclines or anthracenediones (anti-cancer medicines)
  • if you are pregnant or breastfeeding

Intravenous medication must not be used if:
  • you have decreased bone marrow function or if severe oral mucositis (inflammation of the mouth) has occurred during previous cytotoxic therapy
  • you have a generalised infection
  • you have severe hepatic impairment (liver damage)
  • you have severe arrhythmia (irregular heart beat), cardiac impairment (problems with your heart function) or you have had a heart infarction (heart attack)
  • you have had prior treatment with anthracycline in excess of a certain cumulative level

Intravesical (placed directly into the bladder through a catheter) medication must not be used if:
  • you have a tumour that has penetrated the bladder wall
  • you have a urinary tract infection
  • you have a bladder infection
  • there are problems with catheterisation (insertion of a small plastic tube into the urethra)

Take special care with Doxorubicin 2 mg/ml:
  • if you have a bone marrow disease
  • if you have decreased bone marrow function
  • if you have had prior treatment with anthracycline
  • if you have had mediastinal irradiation (radiotherapy in the region between the lungs, where the heart and major blood vessels are located)
  • if you have hepatic impairment (liver damage) or blocked bile flow
  • if you have severe renal impairment (kidney damage)

Using other medicines

Please tell your doctor if you are taking or have recently taken any other medicines, including medicines obtained without a prescription. In particular, inform your doctor if you have used the following medicines:

  • other anthracyclines
  • other preparations with cardiac toxicity (damage to the heart muscles), such as 5-fluorouracil, cyclophosphamide and paclitaxel (anti-cancer medicines)
  • preparations that have an effect on cardiac function, such as calcium antagonists
  • other preparations with hepatic toxicity, such as 6-mercaptopurine (immunosuppressive medicines)
  • cyclosporine (immunosuppressive medicine)
  • verapamil (calcium channel blocker used for heart problems)

DOXORUBICIN 2 MG/ML CONCENTRATE FOR SOLUTION FOR INFUSION

Please read this information carefully before using Doxorubicin and refer to the Summary of Product Characteristics (SPC) for full details.

PRESENTATION

Vials of doxorubicin hydrochloride concentrate for solution for infusion 10mg/5ml, 20mg/10ml, 50mg/25ml, 100mg/50ml and 200mg/100ml. Excipients: Hydrochloric acid, Sodium chloride and Water for injections.

DOSAGE AND METHOD OF ADMINISTRATION

Treatment with Doxorubicin should be supervised by a doctor with extensive experience of cytostatics.

Intravenous administration: The concentrate is injected via the tubing of a freely-running intravenous infusion (Sodium chloride 0.9% intravenous infusion or Dextrose 5% intravenous infusion) over 2-15 minutes. This technique minimizes the risk of thrombophlebitis or perivenous extravasation which can lead to severe cellulitis and vesication. Several dosage regimens exist: The recommended dose is 60-75 mg/m² body surface i.v. as a single dose or in divided doses on 2-3 consecutive days administered with 21 day’s intervals. The lower dose should be given to patients with bone marrow depression. When Doxorubicin is administered in combination with other cytostatics, the dosage should be reduced to 30-60 mg/m². In patients, who cannot receive the full dose, an alternative dosage is 15-20 mg/m² body surface per week. In order to avoid cardiomyopathy, it is recommended that the cumulative total lifetime dose of doxorubicin (including related drugs such as daunorubicin) should not exceed 450-550mg/m² body surface area; 450 mg/m² should not be exceeded in cases of previous radiation of mediastinum, previous or concomitant treatment with potentially cardiotoxic agents. Reduced doses should be used in cases of decreased liver function (see SPC). Dosage in children may need to be reduced, please refer to treatment protocols.

Intravesical administration: Doxorubicin can be given by intravesical instillation for treatment of superficial cancer of the bladder and to prevent relapse after transurethral resection (T.U.R). The recommended dose for intravesical treatment of superficial cancer of the bladder is 30-50 mg in 25-50 ml of physiological saline per instillation. The solution should remain in the bladder for 1-2 hours. During this period the patient should be turned 90o every 15 minutes. To avoid undesired dilution with urine the patient should be informed not to drink anything for a period of 12 hours before the instillation. The instillation may be repeated with an interval of 1 week to 1 month.

Treatment control: Prior to start of the treatment it is recommended to measure the liver function and renal function. There is a need to measure/control blood values and uric acid levels. Analysis of LVEF should be performed in order to optimise the heart condition of the patient prior to the start of the treatment and after each accumulated dose of approximately 100 mg/m².

CONTRAINDICATIONS

Pregnancy, lactation or hypersensitivity to doxorubicin, other anthracyclines or anthracenediones.

Contraindications for intravenous administration: Myelosuppression or severe stomatitis subsequent to previous cytotoxic treatment, general infection, severe impaired liver function, severe arrhythmia, impaired heart function, previous cardiac infarct or previous treatment with anthracyclines with maximal cumulative doses.

Contraindications for intravesical administration: Invasive tumours that have penetrated the bladder (beyond T1), urinary tract infections, inflammation of the bladder or problems with catheterisation.

WARNINGS AND PRECAUTIONS FOR USE

There is a need to follow the treatment control above particularly in at risk patients. Dose reduction may be necessary. See SPC for details. Doxorubicin may potentiate the toxicity of other anticancer chemotherapies or amplify radiation toxicity. A stinging or burning sensation at the site of administration may signify extravasation necessitating discontinuation and restarting in a different blood vessel. Monitor the patient for several weeks. Surgical measures might be necessary. The patient should be informed that the urine might be reddish after administration.

INTERACTIONS

Doxorubicin cardiotoxicity is enhanced by previous or concurrent use of other anthracyclines, or other potentially cardiotoxic drugs or with products affecting cardiac function requiring monitoring of cardiac function. Doxorubicin hepatotoxicity may be enhanced by other hepatotoxic treatments. Doxorubicin used in combination with ciclosporin, cimetidine or phenobarbital might require dose-adjustment. Other interactions have been reported with cyclophosphamide, uric acid levels, digoxin and in recently polio vaccinated patients.

Doxorubicin potentiates the effect of radiation therapy and can, even if administered some considerable time after discontinuation of the radiation therapy.

PHARMACEUTICAL PARTICULARS

Incompatibilities with the following products have been reported: Heparin, aminophyllin, cephalotin, dexamethasone, fluorouracil and hydrocortisone. Doxorubicin should not be mixed with any other products without evidence of compatibility. Doxorubicin 2 mg/ml is compatible with sodium chloride 0.9% and dextrose 5%. Shelf life before opening: 18 months. Store in a refrigerator (2ºC - 8ºC). Keep vial in the outer carton in order to protect from light. Store in an upright position. Any unused portion of the vial should be discarded immediately. The user should follow strict guidelines for the safe handling and disposal of antineoplastic agents.
