What are the uses of this medicine?

Carboplatin (Paraplatin) is approved to be used alone or with other drugs to treat:

• [[Ovarian cancer] that is advanced. It is used with other chemotherapy as first-line treatment. It is used alone as palliative treatment for disease that has recurred (come back) after earlier chemotherapy.
• Carboplatin is also being studied in the treatment of other types of cancer.

How does this medicine work?

• Carboplatin (kar" boe pla' tin) is a cisplatin analog with a carboxy-cyclobutane moiety instead of the chloride atoms which makes it more stable and perhaps less toxic than cisplatin.
• Carboplatin and cisplatin act as alkylating agents causing cross linking between and within DNA strands, leading to inhibition of DNA, RNA and protein synthesis and the triggering of programmed cell death, mostly in rapidly dividing cells.
• Carboplatin was approved for use in cancer chemotherapy in the United States in 1989.
• It is currently indicated for advanced ovarian carcinoma, but is also used in other solid tumors including lung and head and neck cancer.
