Overview
DESCRIPTION Carboplatin injection is supplied as a sterile, pyrogen-free, 10 mg/mL aqueous solution of carboplatin, USP. It is available in multiuse vials containing 50 mg/5 mL, 150 mg/15 mL, and 450 mg/45 mL or 600 mg/60 mL of carboplatin, USP. Inactive ingredients include water for injection, USP. The pH of the solution ranges from 5.0 to 7.0.
Mechanism of Action
CLINICAL PHARMACOLOGY Carboplatin, like cisplatin, produces predominantly interstrand DNA cross-links rather than DNA-protein cross-links. This effect is apparently cell-cycle nonspecific. The aquation of carboplatin, which is thought to produce the active species, occurs at a slower rate than in the case of cisplatin. Despite this difference, it appears that both carboplatin and cisplatin induce equal numbers of drug-DNA cross-links, causing equivalent lesions and biological effects. The differences in potencies for carboplatin and cisplatin appear to be directly related to the difference in aquation rates.
Indications
- INDICATIONS Initial Treatment of Advanced Ovarian Carcinoma Carboplatin injection is indicated for the initial treatment of advanced ovarian carcinoma in established combination with other approved chemotherapeutic agents. One established combination regimen consists of carboplatin and cyclophosphamide. Two randomized controlled studies conducted by the NCIC and SWOG with carboplatin versus cisplatin, both in combination with cyclophosphamide, have demonstrated equivalent overall survival between the two groups (see CLINICAL STUDIES ).
Common Doses
- 360 mg
- 300 mg
- 600 mg
- 60 mL
Dosage
DOSAGE AND ADMINISTRATION NOTE: Aluminium reacts with carboplatin causing precipitate formation and loss of potency, therefore, needles or intravenous sets containing aluminium parts that may come in contact with the drug must not be used for the preparation or administration of carboplatin injection. Single Agent Therapy Carboplatin injection, as a single agent, has been shown to be effective in patients with recurrent ovarian carcinoma at a dosage of 360 mg/m 2 IV on day 1 every 4 weeks (alternatively see Formula Dosing ).
Black Box Warning
Carboplatin injection should be administered under the supervision of a qualified physician experienced in the use of cancer chemotherapeutic agents. Appropriate management of therapy and complications is possible only when adequate treatment facilities are readily available. Bone marrow suppression is dose related and may be severe, resulting in infection and/or bleeding. Anemia may be cumulative and may require transfusion support. Vomiting is another frequent drug related side effect.
Contraindications
- CONTRAINDICATIONS Carboplatin injection is contraindicated in patients with a history of severe allergic reactions to cisplatin or other platinum-containing compounds. Carboplatin injection should not be employed in patients with severe bone marrow depression or significant bleeding.
