Carboplatin is not protein bound; platinum from carboplatin is irreversibly protein bound. Vd is 16 L.


Aquated to produce the active species.


Initial t ½ is 1.1 to 2 h. Postdistribution t ½ is 2.6 to 5.9 h. Cl is 4.4 L/h. 71% is excreted in the urine in 24 h.

Special Populations

Renal Function Impairment

In those with Ccr less than 60 mL/min, the total body and renal Cl decreases as the Ccr decreases. Dosage reduction is recommended.

Indications and Usage


Initial treatment of advanced ovarian carcinoma in combination with other chemotherapy agents. Secondary treatment for palliative treatment of patients with ovarian carcinoma recurrent after prior chemotherapy.

Unlabeled Uses

Small cell and non-small cell lung, head, neck, and testicular cancer.


History of severe allergic reactions to cisplatin or other platinum compounds or mannitol; severe bone marrow depression; significant bleeding.

Dosage and Administration

Ovarian Carcinoma (Single-Agent Therapy)

IV 360 mg/m 2 on day 1 every  4 wk if neutrophil count is at least 2,000/mm 3 and platelet count is at least 100,000/mm 3 .

Ovarian Carcinoma (Combination Therapy with Cyclophosphamide)

IV Carboplatin 300 mg/m 2 plus cyclophosphamide 600 mg/m 2 , both on day 1 every 4 wk for 6 cycles. Do not repeat intermittent courses of the combination until the neutrophil count is at least 2,000/mm 3 and the platelet count is at least 100,000/mm 3 .

Calvert Formula Dosing

IV Carboplatin may be dosed to achieve a target AUC based on the patient's glomerular filtration rate (GFR) using the Calvert formula. The desired target AUC depends on the disease and the patient's treatment status. The Calvert formula calculates the carboplatin dose in mg as follows: Total dose (mg) = target AUC (mg/mL•min) × (GFR [mL/min] + 25).

Dosage Adjustments Based on Lowest Posttreatment Blood Counts

IV If platelets above 100,000/mm 3 and neutrophils above 2,000/mm 3 , then give 125% of adjusted dose from prior course. If platelets are 50,000 to 100,000/mm 3 and neutrophils are 500 to 2,000/mm 3 , no dosage adjustment is necessary. If platelets below 50,000/mm 3 and neutrophils below 500/mm 3 , then give 75% of adjusted dose from prior course. Doses above 125% of the starting dose are not recommended.

Renal Function Impairment (Dosage Adjustment)

IV Baseline Ccr is 41 to 59 mL/min, the recommended dose on day 1 is 250 mg/m 2 ; 16 to 40 mL/min is 200 mg/m 2 ; below 15 mL/min, data too limited to permit a recommendation for treatment.

General Advice

  • Diligently follow institutional and NIH procedures for handling, administration, and disposal of anticancer drugs. Wear appropriate protective equipment when preparing and administering carboplatin.
  • Do not use needles or IV administration sets containing aluminum parts that could come in contact with carboplatin during preparation or administration. Aluminum can react with carboplatin, causing precipitation and loss of potency.
  • Reconstitute powder for injection with sterile water for injection, dextrose 5% in water, or sodium chloride 0.9% injection. Add 5 mL of diluent to 50 mg vial, 15 mL of diluent to 150 mg vial, or 45 mL of diluent to 450 mg vial to produce solution with a final concentration of 10 mg/mL.
  • Reconstituted solution, or premixed aqueous solution, may be further diluted with dextrose 5% in water or sodium chloride 0.9% injection.
  • Do not administer if discoloration, particulate matter, or cloudiness is noted.
  • Administer prescribed dose by IV infusion over at least 15 minutes. Infusion may be lengthened to 24 h, or total dose given as 5 consecutive daily pulse doses, for patient who experiences significant emesis.
  • Administer antiemetic as prescribed before administering carboplatin.


Store aqueous solution and powder for injection at controlled room temperature (59° to 86°F). Protect from light. Reconstituted solution is stable for 8 h at controlled room temperature (77°F). Reconstituted solution does not contain a preservative and any unused solution must be discarded 8 h after reconstitution. Do not save any unused solution for future use. Carboplatin aqueous solution multidose vials are stable at room temperature (77°F) for up to 14 days following initial needle entry.

Drug Interactions


Concomitant use may increase risk of nephrotoxicity or ototoxicity.


Serum concentrations may be decreased, resulting in a loss of therapeutic effect.

Laboratory Test Interactions

Pain (23%); mucositis (1%).




May be cumulative and transfusions required.

Bone marrow suppression

Leukopenia, neutropenia, and thrombocytopenia are dose dependent and are the dose-limiting toxicities; they may result in infection or bleeding.


Vomiting is another frequent drug-related side-effect and usually ceases within 24 h of treatment. The incidence and intensity of emesis have been reduced by antiemetic premedication.


Anaphylactic-like reactions may occur within minutes of administration. Epinephrine, corticosteroids, and antihistamines may alleviate symptoms.



Ensure CBC with differential and platelet count are monitored frequently (at least weekly) during treatment and, when appropriate, until recovery is achieved. Ensure that carboplatin dose is adjusted based on lowest posttreatment platelet or neutrophil value following manufacturer's guidelines.


Ensure electrolytes are evaluated before starting therapy and periodically thereafter during prolonged treatment. Be prepared to treat abnormalities if clinically indicated.


Monitor patient for signs or symptoms of infection or bleeding. Inform health care provider immediately if noted and be prepared to treat appropriately (eg, IV antibiotics, colony stimulating factors, transfusions).


Category D .


Undetermined. Because of possibility of toxicity in breast-feeding infants, discontinue breast-feeding.


Safety and efficacy not established.

Renal Function

Patients with impaired kidney function (Ccr below 60 mL/min) are at increased risk of severe bone marrow suppression.

Peripheral neurotoxicity

Infrequent, but its incidence is increased in patients older than 65 yr of age and in patients previously treated with cisplatin.

Renal toxicity

Limited, but cotreatment with aminoglycosides has resulted in increased renal or audiologic toxicity. Exercise caution when patient receives both drugs.



Bone marrow suppression, hepatic toxicity.
