Abstract

To date, pharmacologic treatments for asthma are predominantly nonspecific anti-inflammatory agents such as corticosteroid and bronchodilators including β2 agonists, which are effective in the majority of patients with asthma. However, therapeutic responses to these agents vary. Severe asthma is characterized by uncontrolled symptoms and recurrent exacerbation with excessive chronic airway inflammation despite adequate and even maximum treatment with these current medications. Although multiple factors can cause poor responses and underlying pathogenic differences are being revealed explaining the various therapeutic responses including steroid insensitivity, effective therapeutic modalities for severe asthma still remained as a major unmet need. Moreover, new members of pharmacological therapeutics and more effective drug-delivery devices (i.e., inhaled device) have been designed, but the proportion of severe asthmatic patients remains stable. Considering nowadays concept of severe asthma, heterogeneity, the improvement of the characterization of the patients is required to achieve appropriate therapeutic responses for severe asthma. It is expected that the determination of phenotype and endotype leads to more effective precision medicine. In this chapter, recent advances in pharmacologic treatment of severe asthma will be introduced including improved current medications, potent nonspecific anti-inflammatory agents, endotype-targeted treatments, specific treatment for comorbidities, and potential therapeutic candidates.
