Cisplatin is administered by slow intravenous infusion. CISPLATIN SHOULD NOT BE GIVEN BY RAPID INTRAVENOUS INJECTION.
Note: Needles or intravenous sets containing aluminum parts that may come in contact with cisplatin should not be used for preparation or administration. Aluminum reacts with cisplatin, causing precipitate formation and a loss of potency.
Metastatic Testicular Tumors
The usual cisplatin dose for the treatment of testicular cancer in combination with other approved chemotherapeutic agents is 20 mg/m
2IV daily for 5 days per cycle.
Metastatic Ovarian Tumors
The usual cisplatin dose for the treatment of metastatic ovarian tumors in combination with cyclophosphamide is 75 to 100 mg/m
2IV per cycle once every 4 weeks (DAY 1).
The dose of cyclophosphamide when used in combination with cisplatin is 600 mg/m
2IV once every 4 weeks (DAY 1).
For directions for the administration of cyclophosphamide, refer to the cyclophosphamide package insert.
In combination therapy, cisplatin and cyclophosphamide are administered sequentially.
As a single agent, cisplatin should be administered at a dose of 100 mg/m
2IV per cycle once every 4 weeks.
Advanced Bladder Cancer
Cisplatin should be administered as a single agent at a dose of 50 to 70 mg/m
2IV per cycle once every 3 to 4 weeks depending on the extent of prior exposure to radiation therapy and/or prior chemotherapy. For heavily pretreated patients an initial dose of 50 mg/m
2per cycle repeated every 4 weeks is recommended.
All Patients
Pretreatment hydration with 1 to 2 liters of fluid infused for 8 to 12 hours prior to a cisplatin dose is recommended. The drug is then diluted in 2 liters of 5% Dextrose in 1/2 or 1/3 normal saline containing 37.5 g of mannitol, and infused over a 6- to 8-hour period. If diluted solution is not to be used within 6 hours, protect solution from light. Do not dilute cisplatin in just 5% Dextrose Injection. Adequate hydration and urinary output must be maintained during the following 24 hours.
A repeat course of cisplatin should not be given until the serum creatinine is below 1.5 mg/100 mL, and/or the BUN is below 25 mg/100 mL. A repeat course should not be given until circulating blood elements are at an acceptable level (platelets ≥ 100,000/mm
3, WBC ≥ 4,000/mm
3). Subsequent doses of cisplatin should not be given until an audiometric analysis indicates that auditory acuity is within normal limits.
Preparation of Intravenous Solutions
Preparation Precautions
Caution should be exercised in handling the aqueous solution. Procedures for proper handling and disposal of anticancer drugs should be utilized. Several guidelines on this subject have been published.
1-4To minimize the risk of dermal exposure, always wear impervious gloves when handling vials and IV sets containing cisplatin.
Skin reactions associated with accidental exposure to cisplatin may occur. The use of gloves is recommended. If cisplatin contacts the skin or mucosa, immediately and thoroughly wash the skin with soap and water and flush the mucosa with water. More information is available in the references listed below.
Instructions for Preparation
The aqueous solution should be used intravenously only and should be administered by IV infusion over a 6- to 8-hour period (see
DOSAGE AND ADMINISTRATION).
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
NOTE TO PHARMACIST:Exercise caution to prevent inadvertent cisplatin overdosage. Please call prescriber if dose is greater than 100 mg/m
2per cycle. Aluminum and flip-off seal of vial have been imprinted with the following statement:
CALL DR. IF DOSE > 100 MG/M
2/CYCLE.
