Irinotesin

Irinotesin (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. Irinotesin 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 Irinotesin

Irinotesin is commonly used for the treatment of colon cancer (colon carcinoma), which may be advanced or metastatic. It can also be used to treat other cancers, such as small cell and non-small cell lung cancer, stomach cancer, ovarian cancer, and pancreatic cancer.

Mechanism of Action

Irinotesin works by interfering with the function of essential enzymes in the body, such as topoisomerase I. These enzymes are necessary for DNA synthesis and repair, and they are found in cancer cells at higher levels than in normal cells. By blocking this enzyme, Irinotesin prevents cancer cells from replicating and causes them to die off naturally.

What is the difference between Irinotesin and other chemotherapy drugs?

Irinotesin works by interfering with the enzyme topoisomerase, which is responsible for enabling a cancer cell to reproduce. Other chemotherapy drugs may work differently, by targeting different enzymes or pathways in the cancer cell.

What other treatments can be used in addition to Irinotesin?

Depending on the type of cancer being treated, your doctor may recommend additional treatments in addition to Irinotesin. For instance, radiation therapy, immunotherapy and targeted drug treatments may be used in combination with chemotherapy, or as a stand-alone treatment.
