Asthma, a life-long disease, affects an estimated 17 million people in the United States. Patients with suboptimally controlled asthma consume a disproportionate share of asthma healthcare resources. Treatment strategies that minimize exacerbations and assist patients in gaining control of their asthma include the use of rescue medications such as beta agonists and medications to control the long-term effects of airway inflammation, such as inhaled and oral corticosteroids.
