What Do We Know About Dupixent (Dupilumab)?

Dupixent is a biological medication that is used to treat different conditions like asthma, atopic dermatitis, and nasal polyps.

It is also given for the treatment of eosinophilic esophagitis. Nasal polyps can be the cause of sinusitis.

It is a monoclonal antibody that blocks interleukin-4 and interleukin-13 by binding to the alpha subunits of these ILs.

A Brief Overview of Biologics in Asthma Management

Use of Dupixent in Asthma

In asthma, the airways get narrow and bulge out with excess mucus production. This results in conditions like shortness of breath along with coughing and wheezing, and sensations of tightness in the chest region can be felt as well.

Dupilumab,  a biologic that is present under the name of Dupixent is available in the market. In clinical trials, it markedly improved the patients’ symptoms, reduced the frequency and severity of asthma exacerbations, and resulted in a reduction in the use of corticosteroids in patients with moderate to severe asthma [Ref].

Mechanism of action of Dupixent:

Interleukins are responsible for causing inflammation in our bodies. They signal the mast cells (also called mastocytes or labrocyte) to produce more and more Immunoglobulin E (IgE) antibodies causing inflammation.

When the process of inflammation begins, eosinophils mobilize themselves and come to the site of inflammation. Along with this systemic inflammation, local inflammation can occur in this region.

In this, the smooth muscle cells increase in numbers and the epithelial barrier is compromised. Airway smooth muscle cells are known to play a critical role in narrowing. Nitric oxide (NO) is released, causing increased production of mucus.

Dupixent blocks the signaling of interleukin 13 and 4 which results in decreased systemic inflammation and local inflammation that eventually leads to the symptoms of asthma being reduced.

Similarly, eczema is also a chronic disorder so it cannot be cured totally. Such patients have to take lifelong treatment to ameliorate the symptoms.

In the case of severe to moderate asthma, the symptoms decline after at least 148 weeks so, it is safe to use for such a long period of duration.

The side effects of the use of Dupixent are normally short-lived. There is little chance that Dupixent can cause long-term side effects, particularly in eye vision.
