Is Dupilumab the Same as Dupixent?
Yes, dupilumab and Dupixent refer to the same therapy in different ways. Specifically, dupilumab is the active drug, while Dupixent is the brand name used in clinical practice. Therefore, when doctors prescribe Dupixent, they are prescribing dupilumab.
Dupixent Dupilumab
Dupixent (dupilumab) belongs to a class of drugs called monoclonal antibodies. It directly targets immune pathways that drive inflammation. As a result, doctors commonly prescribe it for:
- Moderate-to-severe atopic dermatitis (eczema)
- Asthma, especially eosinophilic or steroid-dependent types
- Chronic rhinosinusitis with nasal polyps
- Eosinophilic esophagitis (EoE)
- Prurigo nodularis
In addition, many patients choose Dupixent because it reduces flare-ups and improves quality of life over time.
Dupixent Dupilumab FDA Approval
The FDA approved Dupixent in 2017 for eczema. Since then, regulators have expanded its approvals to include asthma, EoE, and other inflammatory diseases. Consequently, Dupixent now plays a major role in modern immunotherapy.
Dupixent Dupilumab Mechanism of Action
Dupilumab works by blocking interleukin-4 (IL-4) and interleukin-13 (IL-13). These proteins trigger inflammation in many chronic conditions. By inhibiting them, Dupixent reduces swelling, itching, and airway irritation. In other words, it calms the immune system without broadly suppressing it.Dupixent dupilumab injection
