Pharmacologic treatment of bronchiectasis includes: antibiotics, cough suppressants and expectorants, and bronchodilators. Congenital bronchiectasis is less common and often occurs in patients with genetic, immunologic or anatomic defects. Secondary bronchiectasis can be caused by bacterial or viral infections, airway obstruction (malignant tumors, foreign bodies, exogenous compression, etc.), inhalation of toxic substances, etc. Treatment of bronchiectasis mainly includes infection control, with empirical antimicrobial drug therapy (e.g., cefotaxime, levofloxacin, etc.) in the acute phase, and subsequent antibiotic application guided by sputum culture and drug sensitivity results. For patients with obvious airflow limitation, bronchodilators, such as salbutamol, ipratropium bromide, etc., should be given; for those who cough up a large amount of sputum or sputum that is difficult to cough up, sputum chemotherapy (e.g., aminoglutethimide hydrochloride, bromhexine, etc.) can be given. If repeated hemoptysis occurs and the amount of hemoptysis is small, oral antiemetic drugs (Yunnan Baiyao, Cabazitrol, etc.) can be taken; if the amount of hemoptysis is large or the internal medicine treatment is ineffective, surgical treatment should be considered. It should be noted that the above treatments need to be carried out under the guidance of professional doctors, do not take medication by yourself to avoid delaying the condition. Patients with bronchiectasis are advised to seek timely medical treatment.
