Type | biotech | ||||||||||||||||||||||||||||||
Description | Rituxan is a genetically engineered chimeric murine/human monoclonal antibody directed against the CD20 antigen found on the surface of normal and malignant B lymphocytes. The antibody is an IgG1 kappa immunoglobulin containing murine light- and heavy-chain variable region sequences and human constant region sequences. Rituximab is composed of two heavy chains of 451 amino acids and two light chains of 213 amino acids | ||||||||||||||||||||||||||||||

Pharmacology | |||||||||||||||||||||||||||||||
Indication | For treatment of CD20-positive non-Hodgkins lymphoma, chronic lymphocytic leukemia, and rheumatoid arthritis. | ||||||||||||||||||||||||||||||
Mechanism of action | 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. | ||||||||||||||||||||||||||||||
Absorption | Not Available | ||||||||||||||||||||||||||||||
Protein binding | Not Available | ||||||||||||||||||||||||||||||
Biotransformation | Most likely removed by opsonization via the reticuloendothelial system when bound to B lymphocytes, or by human antimurine antibody production | ||||||||||||||||||||||||||||||
