Treating asthma in the age of biologics.

Many patients with severe asthma continue to have high symptom burden despite maximization of conventional therapy. As the understanding of asthma pathophysiology has evolved, however, more personalized therapy options have become available. Asthma biologics are a new class of medications that target the specific pathways that underlie a patient's disease and can reduce the frequency of asthma exacerbations and improve patient quality of life. Clinicians should refer potential candidates to a specialist for further evaluation.
