2 DOSAGE AND ADMINISTRATION
2.1 Recommended Dose
Administer ZINECARD Injection via intravenous infusion over 15 minutes. DO NOT ADMINISTER VIA AN INTRAVENOUS PUSH.
The recommended dosage ratio of ZINECARD to doxorubicin is 10:1 (e.g., 500 mg/m2 ZINECARD to 50 mg/m2 doxorubicin). Do not administer doxorubicin before ZINECARD. Administer doxorubicin within 30 minutes after the completion of ZINECARD infusion.
2.2 Dose Modifications
Dosing in Patients with Renal Impairment
Reduce ZINECARD dosage in patients with moderate to severe renal impairment (creatinine clearance values less than 40 mL/min) by 50% (ZINECARD to doxorubicin ratio reduced to 5:1; such as 250 mg/m2 ZINECARD to 50 mg/m2 doxorubicin) [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)].
2.3 Preparation and Administration
Preparation and Handling of Infusion Solution
Reconstitute ZINECARD with Sterile Water for Injection, USP. Reconstitute with 25 mL for a ZINECARD 250 mg vial and 50 mL for a ZINECARD 500 mg vial to give a concentration of 10 mg/mL. Dilute the reconstituted solution further with Lactated Ringer's Injection, USP to a concentration of 1.3 to 3.0 mg/mL in intravenous infusion bags for intravenous infusion.
Following reconstitution with Sterile Water for Injection, USP, ZINECARD is stable for 30 minutes at room temperature or if storage is necessary, up to 3 hours from the time of reconstitution when stored under refrigeration, 2° to 8°C (36° to 46°F). The pH of the resultant solution is 1.0 to 3.0. DISCARD UNUSED SOLUTIONS. The diluted infusion solutions are stable for one hour at room temperature or if storage is necessary, up to 4 hours when stored under refrigeration, 2° to 8°C (36° to 46°F). The infusion solutions have a pH of 3.5 to 5.5. DISCARD UNUSED SOLUTIONS.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Solutions containing a precipitate should be discarded.
Use caution when handling and preparing the reconstituted solution. The use of gloves is recommended. If ZINECARD powder or solutions contact the skin or mucosae, wash exposed area immediately and thoroughly with soap and water. Follow special handling and disposal procedures.1
Do not mix ZINECARD with other drugs.
Administer the final diluted solution of ZINECARD by intravenous infusion over 15 minutes before the administration of doxorubicin. DO NOT ADMINISTER VIA AN INTRAVENOUS PUSH. Administer doxorubicin within 30 minutes after the completion of ZINECARD infusion.
