Overview of Adalimumab 40mg Injection
Adalimumab, a fully human monoclonal antibody targeting tumor necrosis factor-alpha (TNF-α), is a biologic agent administered as a subcutaneous injection. It is widely used in the treatment of autoimmune and inflammatory diseases. The 40mg dosage, commonly branded as Humira Pen, is designed for biweekly or weekly use depending on the indication and patient response. Adalimumab is approved for various uses by regulatory authorities including the FDA (U.S.), EMA (EU), MHRA (UK), Health Canada, and the TGA (Australia).
Brand Names: Humira® (US, EU, Canada, UK, AU), Amgevita®, Hulio®, Hadlima®, Hyrimoz®, Idacio®, Abrilada®, Imraldi®
Mechanism of Action
Adalimumab exerts its effects by specifically binding to TNF-α, a pro-inflammatory cytokine involved in systemic inflammation. By neutralizing TNF-α, it reduces the inflammatory response in autoimmune diseases. This mechanism provides therapeutic benefits in conditions where TNF-α plays a pathogenic role, including joint damage in rheumatoid arthritis and mucosal inflammation in Crohn’s disease.
