Cisplatin is a chemotherapy drug that is commonly used to treat various types of cancer, including testicular, ovarian, bladder, and lung cancer. It works by damaging the DNA of cancer cells, preventing them from dividing and growing. Cisplatin is administered intravenously and is often used in combination with other chemotherapy drugs to increase its effectiveness. While cisplatin can be an effective treatment for cancer, it can also cause significant side effects, including nausea, vomiting, and kidney damage. Researchers are studying ways to improve the effectiveness of cisplatin and reduce its side effects through the development of new drug delivery methods and combination therapies.
