Drugs List
Therapeutic Indications
Uses
Prevention of cumulative cardiotoxicity caused by anthracycline treatment
Treatment of anthracycline extravasation
Treatment of anthracycline extravasation.
Prevention of chronic cumulative cardiotoxicity caused by anthracycline use in advanced and/or metastatic breast cancer patients who have received a prior cumulative dose of 300mg/metre squared of doxorubicin or a prior cumulative dose of 540mg/metre squared of epirubicin when further treatment is required.
Dosage
Whilst the doses stated below are those recommended by the manufacturer, local cancer network protocols for the relevant indication should be consulted.
Adults
Extravasation Treatment
Dexrazoxane should be given once daily for 3 consecutive days, the recommended dose is:
Day one: 1000mg/metre square.
Day two: 1000mg/metre square.
Day three: 500mg/metre square.
The first infusion should be initiated as soon as possible, within the first six hours after the accident.
Treatment day 2 and Day 3 should start at the same hour (or within 3 hours) as Day 1.
For patients with a body surface area of more than 2 metre square, a single dose should not exceed 2000mg.
Cardiotoxicity Prevention
To be administered as a short intravenous infusion (15 minutes) approximately 30 minutes before anthracycline administration at a dose equal to 10 times the doxorubicin-equivalent dose and 10 times the epirubicin-equivalent dose.
Therefore a dose of 500mg/metre square should be given if a dose of doxorubicin 50mg/metre square or 600mg/metre squared if a dose of epirubicin 60mg/metre square is given.
Children
Cardiotoxicity Prevention (unlicensed use)
Dexrazoxane may be considered in patients under 18 years who require high doses of anthracyclines and who are at greater risk of harmful effects on the heart. See EMA guidance.
Patients with Renal Impairment
Moderate to severe renal impairment (creatinine clearance less than 40ml/minute): reduce dose by 50%.
Patients with Hepatic Impairment
Extravasation: Not recommended.
Prevention of cardiotoxicity: Dosage ratio of anthracycline to dexrazoxane should be maintained. Therefore, if the anthracycline dose is reduced the dexrazoxane dose should be reduced accordingly.
Administration
To be administered by intravenous infusion.
Contraindications
Children under 18 years & cumulative dose <300mg doxorubicin or equivalent
Breastfeeding
Pregnancy
Precautions and Warnings
Children under 18 years
Elderly
Restricted sodium intake
Cardiac failure
Hepatic impairment
History of myocardial infarction
Myelosuppression
Renal impairment - creatinine clearance below 40ml/minute
Unstable angina
Valvular heart disease
Administration of live vaccines is not recommended
Reduce dose in patients with creatinine clearance of below 40ml/minute
Sodium content of formulation may be significant
Advise ability to drive/operate machinery may be affected by side effects
Not all available brands are licensed for all indications
Contains potassium; caution in low potassium diets
Cardioprotective - give 30 mins before anthracycline
Dilute and use as an infusion
Extravasation treatment should be initiated within 6 hours of accident
If extravasation occurs follow local policy & seek expert help immediately
Remove cooling procedures 15 minutes before extravasation treatment
Treatment to be administered by or under supervision of specialist
Monitor cardiac function
Monitor haematological parameters regularly throughout treatment
Monitor hepatic function in patients with hepatic impairment
Monitor patients for development of second primary malignancies
Monitor patients with renal impairment for toxic effects
Monitor plasma potassium in patients at risk of hyperkalaemia
Increased risk of venous thromboembolism
Potentially mutagenic
Not licensed for all indications in all age groups
Male & female: Contraception required during & for 6 months after treatment
When dexrazoxane is used as a preventative pre-treatment administered prior to epirubicin, the clearance of epirubicin may be increased. This has only been reported with high dose epirubicin (120mg to 135mg per square metre) and is of no relevance when dexrazoxane is administered following epirubicin as an emergency treatment of anthracycline extravasation. No dosage adjustments are recommended by the manufacturer however prescribers should refer to local protocols.
Pregnancy and Lactation
Pregnancy
Dexrazoxane is contraindicated in pregnancy.
There is limited data on the use of dexrazoxane in pregnancy. It is not known whether dexrazoxane crosses the human placenta. The molecular weight, lack of plasma protein binding and elimination half-life suggest it will cross the placenta.
Briggs (2015) concludes that as dexrazoxane is used to protect from anthracycline induced cardiomyopathy, treatment should not be withheld because of pregnancy. If an inadvertent pregnancy occurs, the woman should be advised of the possible risk for severe adverse effects on the pregnancy.
Animal studies on rats and rabbits have shown embryotoxic and teratogenic effects.
The effect of concurrent therapies must also be considered.
The use of all medication in pregnancy should be avoided whenever possible; particularly in the first trimester. Non-drug treatments should also be considered. When essential, a medication with the best safety record over time should be chosen, employing the lowest effective dose for the shortest possible time. Polypharmacy should be avoided. Teratogens taken in the pre-embryonic period, often quoted as lasting until 14 to 17 days post-conception, are believed to have an all-or-nothing effect. Where drugs have a short half-life, and when the date of conception is certain, this may allow women to be reassured where drug exposure has occurred within this time frame.

Lactation
Dexrazoxane is contraindicated during breastfeeding.
There is limited data on the use of dexrazoxane during breastfeeding. It is unknown if dexrazoxane or its metabolites are excreted in human milk. The molecular weight, lack of plasma protein binding and elimination half-life suggest that the drug will cross into the breast milk. Due to the potential for serious adverse reaction in the nursing infant the manufacturer advises mothers should discontinue breastfeeding during therapy.
Neonates, infants born prematurely, those with low birth weight, those with an unstable gastrointestinal function or who have serious illnesses may require special consideration. For any infant, if a drug is prescribed to the nursing mother, it should be at the lowest practical dose and for the shortest time. When drug administration is unavoidable and breastfeeding is to continue, minimisation of exposure of the infant to the drug may sometimes be achieved by timing the maternal doses to just after a feeding episode. Infants exposed to drugs via breast milk should be monitored for unusual signs or symptoms. Interactions between the drug received by the infant from the mother's milk and medication prescribed for the infant should also be considered, for example, when the drug given to the infant may prevent metabolism of the drug received via breast milk.
