Dupixent Overview
Dupixent, also known by its generic name dupilumab, is a biologic medication that targets specific proteins involved in inflammation. It is used to treat a range of inflammatory conditions, primarily those affecting the skin and airways.
Mechanism of Action
Dupixent works by blocking the signaling of two key proteins: interleukin-4 (IL-4) and interleukin-13 (IL-13). These proteins play a crucial role in the development and progression of inflammatory responses, particularly in conditions like eczema, asthma, and nasal polyps. By inhibiting the signaling of IL-4 and IL-13, Dupixent helps to reduce inflammation, alleviate symptoms, and improve overall quality of life for patients.
