Pembrolizumab (Keytruda)

Pembrolizumab (Keytruda) is an immunotherapy medication used to treat certain cancers. It works by helping the body's immune system recognize and attack cancer cells more effectively. Normally, some cancer cells evade immune detection by using proteins to turn off immune responses. Pembrolizumab blocks these proteins, particularly PD-1, enabling immune cells to identify and destroy cancer cells. It is administered through intravenous infusion and is used for various cancers like melanoma, lung cancer, and others. Its goal is to enhance the body's natural defense mechanisms to better fight cancer, often leading to improved outcomes.
