A healthcare provider may prescribe ibritumomab (Zevalin®) to treat certain types of non-Hodgkin's lymphoma, a cancer that begins in the lymphatic system. This drug contains ibritumomab tiutexan. Ibritumomab is a synthetic (manufactured) antibody. It is linked to tiutexan, a molecule that helps the antibody attach to a radioactive isotope known as Yttrium-90 (or simply Y-90). Because it attaches to this isotope, ibritumomab is considered a radioactive medication.
Ibritumomab binds to the surface of healthy and certain cancerous cells, signaling the immune system to destroy the cancer cells. In addition, because ibritumomab is linked to a radioactive element, it emits radiation that helps destroy both the cancer cell the medicine is attached to and surrounding cancer cells.
