What is Cimzia (certolizumab pegol)?
Cimzia is used to treat a range of inflammatory autoimmune diseases in adults, including:
- Moderate to severe Crohn’s disease
- Moderate to severe rheumatoid arthritis
- Moderate to severe plaque psoriasis
- Active psoriatic arthritis (PsA)
- Active non-radiographic axial spondyloarthritis with inflammation
- Active ankylosing spondylitis
Cimzia works as a monoclonal antibody and, more specifically, as a TNF blocker, to treat inflammation. TNF alpha (tumor necrosis factor-alpha) is one of several antibodies produced by white blood cells and other parts of the immune system.
Once Cimzia is injected into your body, its active ingredient helps reduce inflammation. Your immune system releases a protein in your body to trigger inflammation called TNF-alpha (tumor necrosis factor-alpha). The active ingredient in Cimzia attaches to TNF-alpha and stops it from working. This limits the amount of inflammation your immune system can cause.
By reducing inflammation, Cimzia can provide relief from the symptoms of inflammatory diseases. It can also limit the damage caused by inflammatory diseases and can stop flare-ups from happening.
