What Is Rituxan and How Does It Work?
Rituximab, a widely used biologic therapy, plays a key role in treating autoimmune diseases. This monoclonal antibody targets CD20, a protein found on the surface of B-cells. By doing so, it helps modulate the immune system, making it effective for conditions like rheumatoid arthritis.
Overview of Rituxan
Rituximab is FDA-approved for several conditions, including rheumatoid arthritis and certain cancers. For patients with rheumatoid arthritis, it is often used in combination with methotrexate, especially when TNF antagonists fail. This combination helps reduce inflammation and slow disease progression.
Key uses of Rituximab include:
- Treating rheumatoid arthritis in combination with methotrexate.
- Managing non-Hodgkin’s lymphoma and chronic lymphocytic leukemia.
- Addressing other autoimmune conditions like granulomatosis with polyangiitis.
Mechanism of Action
Rituximab works by binding to CD20 on B-cells, leading to their depletion. This process helps reduce the overactive immune response seen in autoimmune diseases. In cancer treatment, it targets malignant B-cells, slowing tumor growth.
Key differences in its mechanism include:
- In autoimmune diseases, it modulates the immune system to reduce inflammation.
- In cancer, it directly targets and destroys cancerous B-cells.
Typical treatment involves intravenous infusions, usually administered in cycles. Patients are closely monitored to manage potential side effects and ensure the therapy’s effectiveness.
Common Side Effects of Rituxan
Patients receiving rituximab therapy often experience a range of side effects. These can vary from mild to severe, depending on the individual and the condition being treated. Understanding these side effects helps patients and healthcare providers manage them effectively.
