The article is devoted to the improvement in therapy of bronchial asthma, namely to achievement and maintenance of the control of the disease using combined drugs containing inhaled steroids and long-acting β2-agonists. We used data of multi-center, randomised, double-blind, double-masking 1-year trial CONCEPT. We demonstrated advantages of therapy with fixed-dosed Seretid (fluticasone propionate / salmeterol) compared to flexible dosed Simbicort (budesonide / formoterol). As a result of this

The total length of therapy with systemic steroids at the Seretid group was 46 % less than that at the Simbicort group (301 and 559 days, respectively, р = 0.026).
