A new injection for asthma and COPD attacks is 30% more effective than steroid tablets, reducing the need for further treatment. The study, published in The Lancet Respiratory Medicine, found benralizumab, a monoclonal antibody, to be more effective at the point of exacerbation compared to prednisolone. This could be a significant advancement in treating eosinophilic exacerbations, which make up a significant portion of asthma attacks and COPD flare-ups.
