What is Fasenra?

Fasenra (benralizumab) belongs to a class of drugs known as monoclonal antibodies. It works by reducing the number of eosinophils cells. 

Eosinophilic cells are vital white blood cells that help fight off infections and parasites, however, research suggests that eosinophils may cause the inflammation and airway obstruction seen in eosinophilic asthma

By targeting and removing eosinophilic cells, Fasenra may help prevent airway blockages, asthma attacks, wheezing and shortness of breath, while improving lung function, and allowing for reduced daily steroid use.
