Bronchiectasis is particularly common clinically. The choice of medication for bronchiectasis needs to be determined based on the specific conditions of the patient. Generally, the aggravation of bronchiectasis is caused by recurrent infections, so controlling infections is fundamental in treatment. As for the application of antibiotics, the principle we follow is to select medications based on the different bacterial spectrums in different regions, with the most scientific method being the use of sensitive antibiotics identified through sputum bacterial culture and drug susceptibility tests. Additionally, we also use expectorants like ambroxol and bromhexine. If there is concurrent respiratory distress or a decline in lung function, inhalants such as budesonide-formoterol powder may also be used.
