Final answer:
Cisplatin, carboplatin, and oxaliplatin are antineoplastic drugs, a category of chemotherapy agents used to treat cancer, particularly tumors of the reproductive organs.
Step-by-step explanation:
The drugs cisplatin, carboplatin, and oxaliplatin are classified as antineoplastics, meaning they are used in the treatment of cancer. These compounds are part of a class known as platinum-based drugs, which inhibit cell division in cancer cells. Since their discovery, platinum compounds have been extensively used as chemotherapy agents, with cisplatin being one of the first and most influential. The clinical application of these drugs is substantial, as they are especially effective against tumors of the reproductive organs and have broadened the therapeutic options for various forms of cancer.
