Stepwise Approach Update to the Asthma Treatment

Asthma is a chronic inflammatory disorder of the airways in which many cells and cellular elements play a role. Chronic inflammation is associated with airway hyper-responsiveness, which leads to various airway symptoms. Approaches to asthma treatment have been changing because our knowledge about the pathogenesis and treatment of asthma is continually evolving. Until recently, the stepwise approach to the treatment of asthma was based on a patient' asthma severity. However, new international guidelines have recommended that treatment should be adjusted in a continuous cycle driven by the patient' asthma-control status. If asthma is not controlled on the current treatment regimen, treatment should be stepped up until control is achieved. When control is maintained for at least 3 months, treatment can be stepped down. Ongoing monitoring is essential to maintain control and to establish the lowest step and dose of treatment to minimize cost and maximize safety. However, the stepwise approach and recommended treatments are meant to assist, not replace, the clinical decision making necessary to determine the most appropriate treatment to meet the individual patient' needs and circumstances. This article is a review of the stepwise approach to the treatment of asthma recommended by the Global Initiative for Asthma 2009 and Expert Panel Report 3 of National Heart, Lung, and Blood Institute 2007.
