Mepolizumab Respiratory Pharmacology Guide
The complete learning guide for class, mechanism, indications, adverse effects, kinetics, exam traps, and NBRC-style respiratory pharmacology.
Mepolizumab is a monoclonal antibody that targets interleukin-5 and is used as add-on maintenance therapy for severe eosinophilic asthma. It reduces eosinophil-driven airway inflammation and exacerbation frequency. For NBRC-style questions, associate mepolizumab with IL-5 and eosinophilic asthma.
