Bronchial asthma is a heterogeneous disease characterized by chronic airway inflammation. Different phenotypes can be distinguished based on the underlying type of inflammatory reaction (i.e. TH2 vs. non-TH2 cells), which is particularly important for patients with severe therapy refractive asthma, as new therapeutic strategies are directly targeted against TH2-associated cytokines. Besides symptom control, successful asthma therapy also requires avoidance of exacerbations and fixed airflow limitation as well as the control of pharmacological side effects; therefore, early treatment with low-dose inhaled corticosteroid therapy (ICS) is required, if necessary in combination with a long-acting beta-2 agonist (LABA), preferably as fixed ICS/LABA combination. Before intensifying ICS therapy various factors, such as the inhalation technique have to be checked. Following increased dosage, controlled approaches to reduce ICS dosage again should not be forgotten in order to minimize drug side effects.
