Bronchial asthma (asthma) is a chronic airway inflammation involving a variety of cells, especially mast cells, eosinophils and T lymphocytes; in susceptible individuals this inflammation can cause recurrent episodes of wheezing, shortness of breath, chest tightness and/or coughing, mostly at night or in the early morning; such symptoms are often accompanied by widespread and variable restriction of expiratory flow rate, but can These symptoms are often accompanied by widespread and variable limitation of expiratory flow rate, but can be partially resolved spontaneously or with treatment; they are also associated with increased airway responsiveness to a variety of irritants. Although the etiology and pathogenesis of bronchial asthma have not been fully elucidated, the current treatment methods, as long as the long-term treatment can be standardized, can enable the majority of patients to get ideal control of asthma symptoms, reduce recurrence or even no attacks, and live, work and study as normal people. In general, the goals of successful bronchial asthma treatment are as follows: First, to improve mobility and quality of life. Second, to control symptoms, including nocturnal symptoms, as much as possible. Third, to bring lung function close to optimal. Fourth, to prevent attacks and exacerbations. Fifth, to prevent death from bronchial asthma. Sixth, to avoid affecting other medical problems. Seventh, avoids the side effects of medications. Eighth, to improve self-awareness and ability to deal with acute exacerbations and reduce emergency or hospitalization. The significance of the above treatment goals is to emphasize that (i) treatment should be aggressively pursued to achieve complete symptom control. ②Protect and maintain as normal a lung function as possible. ③ Avoid or reduce adverse drug reactions. In order to achieve the above goals, the key is to have a reasonable treatment plan and to adhere to long-term treatment.
