Understanding Dupixent: A Brief Overview
Dupixent (dupilumab) is a monoclonal antibody used to treat various chronic inflammatory conditions such as atopic dermatitis, asthma, and chronic rhinosinusitis with nasal polyposis. It works by inhibiting the signaling of interleukin-4 and interleukin-13, which are key drivers of inflammation in these conditions.
