Chronic broncho-obstructive pulmonary diseases – bronchial asthma (BA) and chronic obstructive pulmonary disease (COPD) – are a serious clinical problem and an economic burden for practical healthcare. The purpose of the scientific review is to track the evolution of views on the use of bronchodilators and inhaled corticosteroids (ICS) in these diseases and to analyze modern approaches to treatment based on domestic and international guidelines. COPD treatment is aimed at two pathogenetic components – inflammation of the bronchi and the formation of emphysema. The basis of basic therapy remains the use of long-acting bronchodilators of two classes. Treatment of asthma is directed primarily at chronic inflammation of the airways using long-acting bronchodilators. The basis of basic therapy for asthma is the use of inhaled glucocorticosteroids. Currently, the same combinations of bronchodilators and ICS are recommended for both asthma and COPD. One direction is based on the use of ICS with formoterol, a 12-hour drug with a fast onset, in which the drug can be used on demand. The second direction is based on the constant use of ICS/LABA only on a regular basis, but with the ability to use bronchodilators on demand. In this case, ICS with high affinity are more often used. An important component of treatment is adherence to medical prescriptions and the availability of different types of drugs for patients in real clinical practice. At present, conditions have been created in Russia for the implementation of both the treatment of patients with asthma and the treatment of patients with COPD with frequent exacerbations and eosinophilia based on import substitution with modern drugs.
