pembrolizumab
Pembrolizumab is a medication used in cancer treatment, specifically designed to help the immune system recognize and attack cancer cells. It is a type of immunotherapy known as a monoclonal antibody, which works by blocking a protein called PD-1 on the surface of immune cells. This action enhances the immune response against tumors.
Approved for various cancers, including melanoma and non-small cell lung cancer, pembrolizumab is administered through an intravenous infusion. Patients may experience side effects, such as fatigue or skin reactions, but it can be a vital option for those with certain types of cancer that do not respond to traditional treatments.
