What condition does Ibritumomab Tiuxetan treat?

Ibritumomab Tiuxetan is used along with rituximab for the treatment of B-cell non-Hodgkin’s lymphoma. In this type of disease, the tumors develop from lymphocytes which are a type of white blood cell.

This medicine is a monoclonal antibody. A monoclonal antibody is a type of protein that has been designed to recognize and bind to a specific structure called an antigen. It is specifically found in certain cells in the body. The Food and Drug Administration (FDA) has already approved this prescription.

How does Ibritumomab Tiuxetan work?

Ibritumomab Tiuxetan has been designed to target an antigen. It is present on the surface of all B lymphocytes. When this drug is radiolabelled, the radioactive element yttrium 90 is attached to this drug. Once the radiolabelled drug is injected into the patient, the monoclonal antibody transmits the radioactivity to the aim CD20 antigen on the B cells. Once the antibody has bound to the antigen, the radiation can act locally. It also destroys the lymphoma B cells.
