How does diffusion work for humira?

Humira (adalimumab) is a monoclonal antibody that works by binding to tumor necrosis factor-alpha (TNF-α), a pro-inflammatory cytokine involved in autoimmune diseases. In the body, diffusion refers to the passive movement of molecules from an area of higher concentration to an area of lower concentration. After administration, Humira diffuses through bodily fluids to reach inflamed tissues, where it binds to TNF-α, blocking its activity and reducing inflammation. This localized action helps alleviate symptoms of conditions like rheumatoid Arthritis and Crohn's disease.
