Pegfilgrastim is a medication used in cancer treatment to stimulate the production of white blood cells in the body. It is a long-acting form of filgrastim, a drug that helps prevent infections in patients receiving chemotherapy. Pegfilgrastim is administered through injection and works by stimulating the bone marrow to produce more white blood cells, which can help prevent infections during cancer treatment. This research area focuses on the effectiveness and safety of pegfilgrastim in cancer patients, as well as exploring new uses or combinations of the medication in cancer therapy.
