Cardioxane500mg powder for solution for infusion

Dexrazoxane

DOSAGE AND ADMINISTRATION

Cardioxane is administered by short intravenous infusion (15 minutes), approximately 30 minutes before the administration of the anthracycline, with a dose equal to 10 times the doxorubicin equivalent and 10 times the epirubicin equivalent dose.

Therefore, it is recommended to administer Cardioxane at a dose of 500 mg/m2 when using the usual doxorubicin dosing regimen of 50 mg/m2, or at a dose of 600 mg/m2 when using the usual epirubicin dosing regimen of 60 mg/m2.

Pediatric Population

The safety and efficacy of this medicinal product in children from 0 to 18 years have not been established.

Cardioxane is contraindicated in children from 0 to 18 years who are scheduled to receive a cumulative dose less than 300 mg/m2 of doxorubicin or the cumulative equivalent dose of another anthracycline.

Renal Impairment

In patients with moderate to severe renal impairment (creatinine clearance <40ml>

Hepatic Impairment

The dose ratio should be maintained; i.e., if the dose of anthracycline is reduced, the dose of dexrazoxane should be reduced accordingly.

Elderly Patients (over 65 years)

The dose may be adjusted during treatment with Cardioxane according to the patient's health status (in case of heart, liver, or kidney problems).

In case of overdose, symptomatic treatment should be applied.

INSTRUCTIONS FOR USE

Recommendations for Safe Handling

Prescribers should consult national or recognized guidelines on the handling of cytotoxic agents when using Cardioxane. Reconstitution should only be carried out by trained personnel in a designated area for cytotoxics. Pregnant women should not handle the preparation.

It is recommended to use gloves and other protective clothing to avoid skin contact. Skin reactions have been described after contact with Cardioxane. In case Cardioxane comes into direct contact with the skin or mucous membranes, the affected area should be washed immediately with plenty of water.

Preparation for Intravenous Administration

Reconstitution of Cardioxane

For reconstitution, the contents of each vial should be dissolved in 25 ml of water for injectable preparations. The vial contents dissolve in a few minutes with gentle agitation. The resulting solution has a pH of approximately 1.6. This solution should be further diluted before administration to the patient.

Dilution of Cardioxane

To avoid the risk of thrombophlebitis at the injection site, Cardioxane should be diluted before infusion with one of the solutions mentioned in Table 1. The final volume should be proportional to the number of Cardioxane vials used and the amount of infusion solution for dilution, which can range from 25 ml to 100 ml per vial.

The following table (Table 1) summarizes the final volume and approximate pH of the reconstituted and diluted product from one vial and four vials of Cardioxane. The minimum and maximum volumes of infusion solution to be used per vial are indicated in Table 1.

Table 1. Reconstitution and Dilution of Cardioxane Vials

• The sodium lactate 11.2% should be diluted with a factor of 6 to achieve a concentration of 0.16M.

It is normally recommended, to increase the pH of the solution, to use larger dilution volumes (with a maximum of 100 ml of additional infusion liquid per 25 ml of reconstituted Cardioxane). Smaller volumes (with a minimum of 25 ml of additional infusion liquid per 25 ml of reconstituted Cardioxane) may be used if necessary, depending on the patient's hemodynamic status.

The reconstituted and diluted Cardioxane solution is for single use. Once the product has been diluted, it should be used immediately or within the next four hours, provided it is stored at a temperature between 2°C and 8°C and protected from light.

In cases where the solution and its container allow, parenteral drugs should be inspected visually for particulate matter or precipitate. Cardioxane usually appears as a colorless to yellow solution immediately after reconstitution, although some color variability may be observed over time, which does not indicate loss of activity as long as the product has been stored according to the recommendations. However, it is recommended to discard the product if it is not colorless or yellow immediately after reconstitution.

Incompatibilities

Cardioxane should not be mixed with other products except for the dilution solutions mentioned above.

Storage

Do not use Cardioxane after the expiry date stated on the container.

Before Opening

Do not store above 25°C. Store in the original packaging to protect from light.

After Reconstitution and Dilution

The diluted Cardioxane solution is physically and chemically stable for 4 hours at 25°C.

From a microbiological point of view, the freshly prepared infusion solution should be used immediately. Otherwise, the responsibility for the storage time and conditions of the product before administration lies with the user and, in any case, should not exceed 4 hours at a temperature between 2°C and 8°C (in the refrigerator), with protection from light.

Disposal

Disposal of the used medicinal product and materials that have come into contact with it should be carried out in accordance with local regulations. Care and caution should be taken when disposing of items used to reconstitute and dilute Cardioxane.
