Patients with emphysema shortness of breath may use medications such as glucocorticoids, beta2-adrenergic agonists, and anticholinergics. These drugs are usually administered by inhalation and less frequently by mouth. 1. Glucocorticosteroids: Glucocorticosteroids have anti-inflammatory effects, reduce bronchial mucus secretion, and make wheezing smooth, thus playing a role in relieving shortness of breath in emphysema. Representative drugs are budesonide and so on. 2. β2-adrenergic receptor agonists: β2 agonists can dilate the bronchial tubes, so that the gas can pass through the airways smoothly, thus relieving the symptoms of emphysema shortness of breath. The representative drugs are salbutamol, salmeterol and so on. 3. Anticholinergic drugs: this kind of drugs can make acetylcholine not affect the airways, so that the airways can be relaxed and the gas can pass in and out smoothly, which has a very good effect on the symptoms of emphysema shortness of breath. Commonly used drugs are ipratropium bromide, tiotropium bromide and so on. It is recommended that patients pay attention to keep warm, do not smoke, can do breathing exercises such as blowing up balloons, lip-contraction breathing to improve lung function. It is prohibited for those who are allergic to the above drugs, and if any adverse reaction occurs, consult a doctor in time.
