COMPOSITION

Rituximab 500 MG

INDICATION

For treatment of CD20-positive non-Hodgkins lymphoma, chronic lymphocytic leukemia, and rheumatoid arthritis.

PHARMACODYNAMICS

Rituximab binds to the CD20 antigen, which is predominantly expressed on mature B cells and on >90% of B-cell non-Hodgkin's lympohomas. The antibody leads to selective killing of B-cells.

MECHANISM

The Fab regions of rituximab binds to the CD20 antigen on B lymphocytes, while the Fc domain recruits antibodies and complements to mediate cell lysis.

VOLUME DISTRIBUTION

3.1 L

METABOLISM

Most likely removed by opsonization via the reticuloendothelial system when bound to B lymphocytes, or by human antimurine antibody production

HALF LIFE

0.8 hours (mammalian reticulocytes, in vitro)

FOOD INTERACTIONS

Avoid Alcohol
