Topotecan is an anti-cancer medication used to treat certain types of cancer. It is a topoisomerase inhibitor, which means it interferes with the activity of an enzyme called topoisomerase, which is necessary for the replication of DNA in rapidly growing cancer cells. It is usually used to treat ovarian cancer, small cell lung cancer and cervical cancer. Topotecan can be administered intravenously or intra-peritoneally and is usually prescribed as a course of treatment over several weeks or months. Side effects of topotecan may include nausea, vomiting, diarrhea, hair loss, mouth sores and fatigue.
Topotecan is a chemotherapy medication used to treat several types of cancer, including:
- Ovarian cancer: This refers to cancer that has spread from the ovaries to other parts of the body.
- Small cell lung cancer: This is a type of aggressive lung cancer that has recurred (come back) or spread to other parts of the body.
- Cervical cancer: In some cases, topotecan is used to treat cervical cancer that has come back after radiation therapy or has spread to other parts of the body.
Here's a breakdown of how Topotecan works:
- Drug class: Topoisomerase I inhibitor
- Mechanism of action: It works by interfering with an enzyme called topoisomerase I. This enzyme is essential for DNA replication in dividing cells. By blocking this enzyme, topotecan damages the DNA of cancer cells, preventing them from multiplying and ultimately leading to cell death.
Important to know:
- Topotecan is typically administered intravenously (through a vein) by a healthcare professional.
- It can cause side effects, so it's crucial to discuss these potential risks and benefits with your doctor before receiving treatment.
