Dupixent Vs Xolair (Dupilumab Vs Omalizumab)

Dupixent Vs Xolair

Dupixent Vs Xolair is a comparison of the two biologics (monoclonal antibodies) that might be prescribed for diverse illnesses like intense to mild allergies, atopic dermatitis, nasal polyps, chronic sinusitis, allergies, and eosinophilic asthma (Allergic asthma).

These antibodies are produced by way of a single twin of a cellular line having comparable antibodies. Such unique forms of antibodies are very targeted and powerful when treating diseases like asthma and atopic dermatitis.

These “mabs” or monoclonal antibodies are prepared in the laboratory by recombinant DNA technology and purified to the highest degree. Because they are very specific in targeting certain body pathways, they have minimal side effects.

What are Dupixent and Xolair?

Dupilumab, which comes under the name of Dupixent, is a human monoclonal antibody that blocks the signaling process of interleukin-thirteen and interleukin-four.

It actually binds to the receptor complex of IL-4Rα which is shared by both IL-4 and IL-13. Hence, it blocks the functioning of both IL-4 and IL-13.

By binding to the IL-4 receptor complex, it inhibits the functioning of important cells involved in the pathogenesis of asthma and allergic conditions.

Thus, it ends up reducing the production of IgE antibodies by up to 70 %. IgE antibodies are the major direct mediator that causes airway narrowing in asthma. It is also involved in allergic skin symptoms.

Omalizumab, sold by the brand name of Xolair, has a different mechanism of action than Dupixent.

It restricts the binding of IgE antibodies to the IgE receptors that are typically present on the surface of basophils and mast cells.

IgE-mediated activation of allergic cells (mast cells, basophils, and eosinophils) is inhibited by Xolair. This results in less release of the final mediators of inflammation. Hence, it is used in refractory allergic conditions that are mediated by IgE [Ref].

Dupixent Vs Xolair: Indications of Use?

Monoclonal antibodies like Dupixent (Ddupilumab) and Xolair (Omalizumab) are used to treat mild to severe asthma.

Dupixent is also used to treat patients with moderate to severe atopic dermatitis (Eczema) in patients who are unable to keep a hold on their illness with topical prescription medicines or for whom the treatment plans aren’t suitable.

In the treatment of Eczema, Dupixent can be used in addition to or instead of topical corticosteroids. Dupixent is also used to treat chronic rhinosinusitis with nasal polyposis and has recently got FDA approval for the treatment of eosinophilic esophagitis.
