Nebulized inhalation has a relatively good relief effect on patients with emphysema. Nebulized inhalation drugs can be chosen from budesonide suspension, terbutaline nebulizer, compound ipratropium bromide and so on. These drugs are widely used in clinical practice, and are more effective because the molecular particles are smaller and can act directly on the airways locally. However, the main cause of acute exacerbation of emphysema is infection, so it is necessary to use anti-infective drugs in combination, and the patient’s clinical symptoms cannot be relieved by nebulized inhalation alone.
