From: Attitudes and actions of asthma patients on regular maintenance therapy: the INSPIRE study
(a) Use of short-acting β2-agonist (SABA) rescue medication and (b) use of inhaled corticosteroid (ICS) maintenance medication during the different stages of an asthma worsening. All patients used ICS plus a separate long-acting β2-agonist (LABA), ICS alone, or a combination ICS/LABA product for regular maintenance therapy. Data are based on all patients who reported using each medication type at each particular stage.
