Abstract: In recent years, serious and numerous advances have been made in the treatment of bronchial asthma. These results are associated with the significant efficacy of inhaled corticosteroids in topical diagnosis and pathogenetic treatment of bronchial asthma. However, despite the results achieved, the fight against this disease is not satisfactory. In patients with severe bronchial asthma, inhaled corticosteroids are more effective when used in combination with β2-agonists. Almost every second asthma patient is concerned about nighttime attacks. More than half of the patients had limited physical activity, and one in three lost the ability to work. Most patients are forced to see a doctor because of the exacerbation and progression of the disease.
