Dupilumab Respiratory Pharmacology Guide
The complete learning guide for class, mechanism, indications, adverse effects, kinetics, exam traps, and NBRC-style respiratory pharmacology.
Dupilumab is a monoclonal antibody that blocks IL-4 receptor alpha signaling, reducing both IL-4 and IL-13 mediated inflammation. It is used for severe asthma, especially type 2 inflammatory disease, and is also widely used in atopic dermatitis and nasal polyps. Students should associate Dupilumab with IL-4 receptor blockade.
