Irinotecan PhaRes

Irinotecan PhaRes (brand name Camptosar®) is a type of chemotherapy medication used in the treatment of cancer. It is a derivative of camptothecin, a natural alkaloid found in the Cinnamoni species of plants. Irinotecan PhaRes works by interfering with the ability of certain cancer cells to divide and multiply. It is used in combination with other medications to treat several types of cancers, including colorectal, lung, and ovarian.

Uses for Irinotecan PhaRes
