Bronchial asthma is frequent chronic respiratory disease and respresents a serious health problem throughout the world. During the past two decades many scientific advances have improved our understandings of asthma that we can treat and control effectively. A comprehensive conception of asthma management is directed on control of the disease. The classification by the level of asthma control is recommended as controlled, partly controlled and uncontrolled. Asthma treatment is organised into five steps selecting intensity of treatment (dosages and/or number of medications) required to achieve control. At all steps, a reliever medication should be provided for as-needed use. At steps 2-5, a variety of controller drugs are available - glucocorticosteroids, leucotrien modifiers and other therapeutics options.
