Adalimumab - Medicine Description

Adalimumab is a biologic medication used primarily to treat autoimmune conditions. It works by targeting a specific part of the immune system to help reduce inflammation and prevent damage to joints, skin, and other organs.

Drug Class:

• Drug Class: Tumor Necrosis Factor (TNF) Inhibitors
• Categories: Immunosuppressants, Monoclonal Antibodies, Anti-Rheumatic Agents

Active Ingredient Name:

• Active Ingredient: Adalimumab

Popular and Other Names:

• Humira (Brand Name)

Mode of Action:

Adalimumab is a TNF-alpha inhibitor that works by blocking tumor necrosis factor-alpha (TNF-α), a substance in the body that causes inflammation in autoimmune diseases like rheumatoid arthritis, Crohn's disease, and psoriasis. By inhibiting TNF-α, adalimumab helps reduce inflammation, prevent further tissue damage, and improve symptoms.
