What is the role of diethyl fumarate in the treatment of multiple sclerosis?

• A. Potent immunosuppressant
• B. Selective immunosuppressant that delays progression
• C. Monoclonal antibody
• D. Antipsychotic agent

Answer: (B)

Diethyl fumarate is primarily used in the treatment of multiple sclerosis (MS) due to its unique mechanism of action that focuses on modulating the immune system. It acts as a selective immunosuppressant, which helps to reduce the frequency of relapses and progression of disability associated with MS. The compound exerts an anti-inflammatory effect and promotes a shift in immune response from pro-inflammatory to anti-inflammatory through pathways that involve nuclear factor (erythroid-derived 2)-like 2 (Nrf2) activation. By enhancing the body's antioxidative stress response and reducing inflammatory processes, diethyl fumarate contributes to stabilizing the disease and delaying its progression over time. This selective action differentiates it from broad-spectrum immunosuppressants, making it a targeted therapeutic option for patients with relapsing forms of MS. Its safety profile and tolerability contribute to its use in clinical practice as a long-term treatment approach.
